Wilston Grange Precinct Study Transport Engineering Studies Wilston Grange Precinct Transport Study Technical Report April 2015 Prepared for Transport Network Operations Transport Planning & Strategy - Prepared by Transport Engineering Studies Group Transport Planning & Strategy - 81915445 Final Draft Page 1 Wilston Grange Precinct Study Transport Engineering Studies 6.5 Road Safety Audit As part of Council’s investigation of future needs for the study area, a Road Safety Audit (RSA) was undertaken to identify existing deficiencies within the road network which may potentially compromise user safety. Given the magnitude of the study area, the RSA was broken down into three sub areas, as illustrated in Figure 0.1. The audit scope was limited to the highlighted streets within each of the sub-area boundaries which were determined based on the streets role in the road network and historical crash data. Figure 0.1 : Road Safety Review Sub-Areas 81915445 Final Draft Page 2 Wilston Grange Precinct Study Transport Engineering Studies Transport Engineering commissioned Point 8 to conduct the RSA for Sub-Area 1, Arup to conduct the RSA for Sub-Area 2 and MWH to conduct the RSA for Sub-Area 3. 6.5.1 Road Safety Audit Methodology The audits were completed in accordance with the requirements of Austroads, Guide to Road Safety: Part 6 Road Safety Audit, 2009. The essential elements of a road safety audit are: A formal process and not an informal check; An independent process; Carried out by persons with appropriate experience and training; and Restricted to road safety issues. The methodology adopted generally follows the format and topics outlined in Austroads Checklist 6. Risk rating of safety issues is defined as per Austroads Part 6: Table 4.4 as being Intolerable, High, Medium and Low. In the Austroads Guide Intolerable implies that there should be some measure of risk management considered to potentially reduce its likelihood. A number of mitigation solutions made as a result of the RSAs could be relatively straightforward in an engineering sense but may require alternative solutions that have community acceptance. In this report the issues with the highest risk identified in the Road Safety Audit are referred to as a Very High risk. 6.5.2 Limitations of Road Safety Audit Whilst road safety audits are detailed in some respects, they represent a relatively brief assessment of a road network or of an associated feature and are not intended to extend or investigate every aspect which may potentially have some level of influence on road function and safety. It is not a check against the design standards and does not imply compliance with the standards nor does it guarantee safety. There were a number of issues raised in the RSAs that will require further detailed assessment to determine conformity with all relevant standards and what, if any, further action will be required going forward. For instance, the audit identified that roadway lighting is insufficient however the actual levels or quality was not verified in absolute terms. The aim of an audit is to highlight potential safety issues and have them formally considered by the asset owner (Council), in conjunction with all other asset considerations. Each safety issue raised was assed qualitatively to determine appropriate risk ranking for each issue. It should also be noted that the determination of risk ratings as per the categories listed in Error! Reference source not found. is not based on quantitative process and instead relies on professional judgement and experience of the audit team. Given that there were three different auditors involved in the road safety audit, the risk category associated with each identified issue for each sub-area is subjective and not necessarily consistent across sub-areas. The auditors have pointed out that no guarantee is made that every deficiency has been identified. Further, if all recommendations in the report were to be followed, this would not 81915445 Final Draft Page 3 Wilston Grange Precinct Study Transport Engineering Studies guarantee that the existing roads are safe, rather the adoption of the recommendations should improve the level of safety of the roads. A database using Excel has been developed for the study area which can be filtered by categories. These categories were developed as per Austroads guidelines and include: - Road Alignment & Cross Section; Signs & Lighting; Markings & Delineation; Crash Barriers & Clear Zones; Traffic Signals; Pedestrians & Cyclists; Bridges & Culverts; Pavement/Parking and Miscellaneous. This database will be provided separately in digital format. Findings for each sub area have been discussed separately below. 6.5.3 Road Safety Audit: Sub – Area 1 While audit findings were recorded for each street/intersection, there were a number of road safety issues that were identified by the auditors as repeatedly occurring precinct wide. These are summarised below: Vegetation overhanging or encroaching within the carriageway; Need for improved street lighting; Faded/worn pavement markings; Narrow footpaths or limited footpaths; Low hanging power lines which cross the carriageway; Missing Tactile Ground Surface Indicators on most kerb ramps; Inappropriate location of roadside furniture behind road kerb; and Need for improved signs. Audit findings, illustrated in Figure 0.2 and in Table 0.1, indicated that the safety issues generally occur along major carrying roads including Grange Road, Raymont Road, Days Road and Wilston Road. In addition to road sections, the intersections of Grange Road/Raymont Road, Grange Road/Days Road, Wilston Road/Daisy Street, Wilston Road Level Crossing and Wilston Road/Newmarket Road were identified as areas of concern. 81915445 Final Draft Page 4 Wilston Grange Precinct Study Transport Engineering Studies Figure 0.2 : Sub-Area 1: Audit Finding Locations 81915445 Final Draft Page 5

Royal Pde Southerden Ave Stevenson St Wickham St Wilston Rd Page 8 Wilston Grange Precinct Study Transport Engineering Studies The RSA identified a large number of issues, and for ease of reporting a detailed summary of issues with a risk rating of “Very High” or “High” follow. There were five specific issues with a risk rating Very High which is listed in Table 0.2. These were identified at intersections with high volume roads with limited sight distance with right turns currently permitted from the side road. Although execution of right turn bans is straightforward, this treatment affects convenience of access and may not be supported some sections of the community. Alternative solutions could be developed that retain access and improve safety, but would be more costly to achieve and still may not be supported by the community directly affected. Table 0.2 : Locations Identified with Very High Risk Location Issue/Risk Description Recommendation Murrell Street / Wilston Road Sight distance to the north from Murrell Street is limited by the level crossing infrastructure. Risk of conflict between turning and through traffic at the intersection. Consider banning the right turn into Wilston Road from Murrell Street. Consider signalisation of the two intersections as a dual signalised intersection. Days Road/Wilston Road Sight distance at Days Road/Wilston Road (travelling northbound) is limited and presents a difficult situation for the driver. It is difficult for drivers to see oncoming traffic before entering Days Road. Visibility is restricted in both directions by adjacent properties and on-street parking. Risk of conflicts between turning and through traffic at the intersection. Consider banning right turn movement at intersection. Consider establishing parking restrictions on Days Road west of the intersection to maximise sight distance. Grange Road/Howard Street Sight distance out of Howard Street is limited and there is a risk of conflict between turning and through traffic at the intersection. Crash history includes incidents at the intersection involving right turning vehicles. Consider banning movements. right turn Grange Road/Dennis Street Sight distance out of Dennis Street is limited and there is a risk of conflict between turning and through traffic at the intersection. Crash history includes incidents at the intersection involving right turning vehicles. Consider banning movements. right turn Grange Road/Myrtle Street Sight distance out of Myrtle Street is limited and there is a risk of conflict between turning and through traffic at the intersection. Crash history includes past incidents at the intersection involving right turning vehicles. Consider banning movements. right turn Source : Wilston Grange Precinct Area 1 Road Safety Report - Point 8 81915445Final Draft Page 9 Wilston Grange Precinct Study Transport Engineering Studies Table 0.3 lists the High risk ratings from the RSA and whether the issue and associated recommendation has a history of recorded crashes and highlighted by the community as an issue. Table 0.3 : Key Road Network Related Audit Concerns : Sub-Area 1 Location RSA Category Issue/Risk Description RSA Risk RSA Recommendation Alderley Avenue Road Alignment and Cross Section The vertical crest creates sight distance issues for properties with direct access driveways. Potential for vehicle conflicts. High Further investigation is necessary. Alderley Avenue/Park Avenue Road Alignment and Cross Section Sight distance at Park Avenue is limited by a combination of screening on the overpass and pedestrian bridge. Screening prevents view of pedestrians and cyclists on bridge. Risk of conflict between left turning (into Park Avenue) vehicles pedestrians/cyclists. High Consider reducing screen height at Park Avenue end. Consider installation of advanced warning signs prior to overpass. Campbell Terrace Road Alignment and Cross Section Sight distance to the east at the Raymont Road intersection is limited. Risk of conflict between turning and through traffic at the intersection. High Consider right turn restrictions at this intersection. Chelford Street/Raymont Road Road Alignment and Cross Section Sight distance at Chelford Street/Raymont Road is limited in both directions. While no crashes have been observed at this location, Raymont Road has high traffic volumes at relatively high speed (relative to Chelford). Risk of conflicts between turning and through traffic at the intersection. High Consider right turn restrictions from Chelford Road into Raymont Road. Consider advanced side street warning signage on Raymont Road. Chermside Street Parking On-street parking is permitted within close proximity to Raymont Road access point/median island. Occupation of these parking bays restricts carriageway width. Risk of rear end incidents with through traffic on Raymont Road due to vehicles slowing at the narrow throat. Potential for conflict between turning vehicles and parked vehicles. High Consider extending the existing parking restriction a further 10m north with signage and linemarking. Chermside Street Miscellaneous Observed traffic volumes appear high for the order of the road. It is possible that Chermside Street is used as a rat run route around the Grange Road/Raymont Road intersection signals. This is an issue as the sight distance at Blandford Street/Grange Road is limited and raises the risk for additional incidents at the intersection associated with risks identified above. High Consider implementing LATM treatments to deter rat running traffic in Chermside Street. Chermside Street/Raymont Road Road Alignment and Cross Section Sight distance to the west is limited at Raymont Road/Chermside Street and further restricted by the presence of a bus stop (on Raymont Road). Risk of conflicts between turning and through traffic at the intersection. High Consider relocation of the bus stop. Clowes Lane Road Alignment and Cross Section Sight distance at Saleyards Lane intersection is limited due to adjacent property lines. Risk of conflict between turning and through traffic at the intersection. High Consider establishment of one way directional control heading eastbound on Clowes Lane. Colston Road/Days Road Road Alignment and Cross Section The petrol station egress is extremely close to the Days Road intersection. Right turning vehicles may have difficulty exiting the driveway due to the high volume of vehicles from Days Road and limited sight distance to the south due to a crest on Colston Road. There is risk of vehicle conflicts. High Consider banning right turns from petrol station egress. David Street Road Alignment and Cross Section Sight distance looking to the north on the western leg of David Street is limited due to a vertical crest. Risk of conflicts between turning and through traffic at the intersection. High Consider right turn restrictions at this intersection. Days Rd / Grange Rd Markings and Delineation Pavement arrows on the eastern leg of the Days Road intersection are worn and may cause confusion about turning designations at the intersection. All line marking at the intersection is starting to wear and fade. High Consider repainting intersection line marking with thermoplastic line marking to increase visibility and longevity. 4 Days Rd / Grange Rd Markings and Delineation Geometry for dual right turns northbound is narrow for two vehicles simultaneously High Investigate improvements 4 81915445 Final Draft options for to intersection Crash History Community Issue 1 1 1 Page 10 Wilston Grange Precinct Study Location RSA Category Transport Engineering Studies Issue/Risk Description RSA Risk turning, particularly large vehicles (there is a bus route that uses this movement). Vehicles in the outside lane were observed crossing guide lines and into adjacent lane. There is a risk of side swipe collisions for northbound vehicles turning right from Days Road. RSA Recommendation Crash History geometry or phasing options to maintain existing capacity with only single right turn lane. Days Rd / Grange Rd Miscellaneous During peak periods, congestion of the northbound left turn from Days Road into Grange Road may result in through movements on Days Road (eastbound) travelling in the westbound lane opposing traffic (due to driver impatience). The high volume of turning movements at service station access which may not expect an eastbound vehicle in the westbound lane. High Investigate improvements to increase northbound capacity from Days Road into Grange Road. Consider physical restrictions on Days Road between Colston and Grange. 4 Days Road Road Alignment and Cross Section Sight distance from all side streets is limited throughout Days Road. Risk of conflicts between turning and through traffic at the intersection. High Refer to detailed recommendations for each side street. Consider signage strategy between Colston Road and Sidney Street to advise motorists to be aware of turning traffic from side streets with limited sight distance. 3 Days Road Road Alignment and Cross Section The horizontal curves and vertical crests have a limited design speed. There is risk of vehicle crashes, pedestrian crashes and vehicles leaving the carriageway due to inappropriate speeds for the road environment. High Consider LATM treatments, reduced speed limits, upgrade of infrastructure to allow for prevailing vehicle speeds. 3 Days Road Pedestrians The footpaths on both sides of the road are very narrow and are occasionally obstructed by power poles. Wheelie bins were observed to impede the path for pedestrians and force them to walk within the road carriageway. High Consider alternative refuse collection arrangements. Consider increasing warning signs for pedestrians. Consider reducing posted speed of road due to high volume of pedestrians during peak hour. Consider options to increase footpath width in isolated locations. 3 Days Road Pedestrians A high number of pedestrians have been observed crossing Days Road at varying points. Limited pedestrian crossing facilities exist between Southerden Avenue And Colston Road which encourages crossing at random locations. High Consider implementing a pedestrian crossing facility between Southerden Avenue and Colston Road i.e. zebra crossing. 3 Road Alignment and Cross Section Sight distance at Mina Parade is limited. Risk of conflict between turning and through traffic at the intersection. The road intersects with South Street and Mina Parade with unconventional geometry which creates confusion and priority needs to be more clearly defined needs to be better defined. Risk of conflict between vehicles at Gracemere Street and South Street. High Consider implementing intersection treatment which clearly defines priorities. Consider implementing a “half-roundabout) at the intersection of South and Gracemere with Mina Parade. 1 Grange Road Miscellaneous The free flow speed of traffic was perceived to be higher than appropriate for the road environment, geometry and lane widths. High speeds increase the likelihood of crashes due to larger stopping distances and sight distances. The risk of injury severity is increased due to the higher perceived speed environment. High Consider whether a speed limit review is warranted. 9 Grange Road/Blandford Street Road Alignment and Cross Section The sight distance at Grange Road intersection is limited. Crashes have been observed at this location. Risk of conflicts between turning and through traffic at the intersection. High Consider further restrictions on turning movements at this intersection, and advanced warning on Grange Road to advise the presence of Blandford Street intersection and acute angle of intersection geometry. Grange Road/Blandford Street Road Alignment and Cross Section Sight distance to Blandford Street (northbound direction) is limited due to vertical crest. Risk of conflict between turning and through traffic at the intersection. High Further investigation required. Grange Road The left turn into Blandford Street is acute, High Consider advance warning signage Gracemere (South of Road) 81915445 Street Days Final Draft Community Issue Page 11 Wilston Grange Precinct Study Transport Engineering Studies Location RSA Category Issue/Risk Description Road/Blandford Street Alignment and Cross Section requiring northbound vehicles to slow down to considerably low speed relative to through traffic. Risk of rear end crashes. Grange Road/Myrtle Street Road Alignment and Cross Section Right turns into Bega and Myrtle Streets (heading northbound) are a risk due to limited sight distances from vertical curvature. Risk of conflicts between turning and through traffic at the intersection. High Consider banning right turn movement from Grange Road. 4 Grange Road/Raymont Road Intersection Traffic Signals The filtered right turn arrangement causes cars to prop at a high volume intersection. Vertical crest south of signals limits sight distance to the south which will increase the average time required to identify a safe gap in traffic to turn right. Risk of rear ending or conflict between turning vehicles and through traffic. High Consider providing controlled right turn lanterns and phasing. 6 Grange Road/Raymont Road Intersection Road Alignment and Cross Section The vertical crest prior to signals limits sight distance to the back of queues northbound. Risk of rear end incidents. Note: Advanced signal flashing LED sign is already installed south of the intersection to reduce this risk. High Consider providing additional lanterns that are mounted higher than conventional standard and visible over the crest. 6 Mina Parade Road Alignment and Cross Section The crest between Alderson Street and Gracemere Street restricts sight distance. Additionally, parking is allowed in this section of Mina Parade and restricts carriageway width to comfortably accommodate two-way traffic. Risk of head on collisions. High Consider installation of crest advanced warning signage. Consider restricting parking between Alderson and Gracemere Streets. 1 Mina Parade Pavement The pavement and verge conditions in the south eastern corner of the pedestrian bridge present a tripping hazard for pedestrians and a fall hazard for cyclist. Risk of injury to pedestrians and cyclists. High Consider repairing of pavement or provide additional fencing to direct cyclists to exit bridge at centre rather than the left hand side (note the cycle route requires cyclists to make a priority left turn at this intersection). 1 Mina Parade Cyclists Signage and bollards at both end of the pedestrian bridge is an obstacle for cyclists. There is a risk of injury to a cyclist attempting to turn left at speed at either end of the bridge. High Given this is a designated cyclist route, a high priority should be given to safety of cyclists in this section. Consider a detailed design investigation to provide a safe environment for pedestrians and cyclists. 1 Montpelier Street Road Alignment and Cross Section The steep grade (estimated at greater than 10%) approaching Wilston Road leads to vehicle speeds significantly higher than 50km/h. The carriageway is very wide and driver perception may be that high speeds are appropriate. Potential for vehicles to fail in braking for stop control at Wilston Road. Risk of vehicle conflicts. High Consider LATM treatments. Consider stop pavement markings at intersection with Wilston Road. Consider a painted edgeline to reduce lanewidth approaching Wilston Road. Consider “dragonteeth” linemarkings to slow traffic prior to intersection. 2 Montpelier Street/Wilston Road Road Alignment and Cross Section Sight distance at Wilston Road is limited in both directions. Risk of conflicts between turning and through traffic at the intersection. High Consider peak hour right turn restrictions. An alternative route north via Colston Road is considerably safer. 1 Moran Street/South Pine Road Road Alignment and Cross Section Vehicles turning right out of Moran Street onto South Pine Road must cross three lanes. Risk of conflicts between turning and through traffic at the intersection. High Consider banning right turns out of Moran Street during peak hour. Newmarket Road Markings and Delineation RRPMs are missing from Wilston Road to Enoggera Road. Potential for vehicles to travel off alignment. High Consider installation of RRPMs with priority being given to centreline markers. 5 Newmarket Road Cyclists The bicycle route on Lind Street leads into a narrow pedestrian footpath on Newmarket Road. Risk of pedestrian/cycle collisions. High Consider installation of warning signs for approaching cyclists and pedestrians. 5 Newmarket Road Signs The advertisement that is immediately visible upon turning right from Enoggera Road into Newmarket Road appears to be over sized and too bright for its location. There is a risk of incident through driver distraction. High Investigate appropriateness of sign location, size and lighting. 5 Progress Parade Road Alignment and Cross Section The road shoulder immediately in front of the preschool entrance acts as an unofficial passenger drop off zone. It is in a location High Consider establishing a no standing zone and creating a passenger drop off zone in a 81915445 RSA Risk Final Draft RSA Recommendation Crash History Community Issue for side street on Grange Road. Consider intersection treatment at Blandford Street. Page 12 Wilston Grange Precinct Study Location RSA Category Transport Engineering Studies Issue/Risk Description RSA Risk that restricts through traffic to pass propped vehicles safely. Through traffic may enter the opposing lane and is at risk of head on collision. RSA Recommendation Crash History suitable location. Progress Parade/Andrew Street Road Alignment and Cross Section Access to Andrew Street is at an extremely high angle that does limit sight distance to the west when exiting. This high angle also makes it very difficult for vehicles to turn left, or U-turn in this case, without encroaching opposing lanes. Sight distance to the east is limited due to the horizontal curvature of Progress Parade. There is a high risk for side swiping and head on incidents. High Consider banning left turns out of Andrew Street. Consider providing a convex driveway mirror to allow exiting vehicles to identify approaching traffic. Raymont Road/Billington Street Road Alignment and Cross Section Sight distance to the east at the Billington Street intersection is limited. On-street parking contributes to this limitation. Risk of conflict between turning and through traffic at the intersection. High Consider restriction of right turn movements from Billington Street. Raymont Road/Blandford Street Crash Barriers and Clear Zones The steel ARMCO barrier at Blandford Street needs a standard end treatment and does not appear to serve any purpose. Increased risk of injury severity due to spear hazard. High Consider removing barrier. Raymont Road/Plymouth Street Crash Barriers and Clear Zones The steel ARMCO barrier at Plymouth Street needs a standard end treatment and shows evidence of striking. Increased risk of injury severity due to spear hazard. High Consider replacing barrier with one of a suitable standard or retrofitting of a new end treatment. Raymont Road/Royal Parade Road Alignment and Cross Section Sight distance at both legs of Royal Street is limited due to vegetation within the verge. Risk of conflicts between turning and through traffic at the intersection. High Consider vegetation clearing to improve sight distance at the intersection. 2 Raymont Road/Royal Parade Markings and Delineation The westbound carriageway width at the intersection of Raymont Road/Royal Parade is too narrow for traffic to safely pass turning traffic at speeds (which are high due to the downgrade section of road). There is risk of vehicle conflicts between Raymont Road through traffic and vehicles propped at Royal Parade. A near miss incident was observed during the site inspection. High Consider reconfiguration of line marking at the intersection to incorporate a wider line marked median to visually reduce the carriageway width to deter drivers from attempting to pass right turning vehicles at speed. Alternatively, consider whether a right turn lane can be provided in the carriageway width available. 2 Raymont Road/Royal Parade Lighting Street lighting at the Royal Parade pedestrian refuge limits visibility of crossing pedestrians at night time. Increased risk of injury to pedestrians. High Consider investigation of lighting conditions and potential improvements. 2 Raymont Road/Welbeck Street Road Alignment and Cross Section Sight distance looking west from Welbeck Street intersection is limited due to vertical crest. Risk of conflicts between turning and through traffic at the intersection. High Consider an advanced side street warning sign on Raymont Road. Raymont Road/Welbeck Street Road Alignment and Cross Section Sight distance westbound towards Welbeck Street is limited due to vertical crest. The presence of on-street parking and driveways on the descending side of the crest is restricted. Risk of conflict between through traffic and vehicles entering/exiting the carriageway. Risk of pedestrian collisions and cyclist "dooring" incidents. Crashes have been recorded at this location. High Consider implementing parking restrictions and erecting "concealed driveways" warning signage prior to the crest. Raymont Road/Welbeck Street Signs Westbound grade, after vertical crest at Welbeck Street, encourages high speeds downgrade. Risk of vehicles travelling at speeds inappropriate for the road environment. High Consider repeating speed signs and line marking treatments or speed control devices that reduce perceived carriageway width. Robe Road Road Alignment and Cross Section Sight distance at the Days Road intersection is limited in both directions. Risk of conflicts between turning and through traffic at the intersection. High Consider banning right turn from southern leg of intersection and trimming vegetation around intersection. 1 Southerden Avenue/Days Road Road Alignment and Cross Section Sight distance at Days Road is limited. Risk of conflict between turning and through traffic at the intersection. High Consider restriction of right turns at this intersection. 1 Ward Street Signs No advisory speed sign present before sharp High Consider Street/Days 81915445 Final Draft Community Issue installation of curve Page 13 Wilston Grange Precinct Study Location RSA Category Transport Engineering Studies Issue/Risk Description RSA Risk right turn into Erneton Street. Wheel scuff marks on the median island suggest that vehicles travel through the corner at speeds higher than appropriate for the geometry. RSA Recommendation Crash History advisory signage prior to Erneton Street. Consider parking restrictions on Erneton Street near Ward Street. Waterford/Wakefield Street Crash Barriers and Clear Zones The barrier end treatments used within the Wakefield Street median are a potential spear hazard and need to be upgraded. Risk of increased injury severity due to spear hazard. High Consider replacement treatments. Wickham Street Signs The T intersection advanced warning sign on approach to Ward Street needs to be amended to suit the existing road arrangements. The existing arrangements prioritise a sharp turn into the northern leg of Ward Street. The southern leg of Ward Street gives way. There is a risk of rear end incidents as drivers may be expecting to come to a full stop after the vertical crest at North Street. High Consider replacement of T intersection warning sign with curve advisory warning sign. Traffic Signals The right turn from Newmarket Road into Wilston Road is a filtered right turn through tight geometry. This is a high risk for rear end incidents as well as a risk of through-right turn crashes due to the high volume of traffic on Newmarket Road. High Consider changing phasing arrangements to allow for a right turn phase or reconfiguration of the intersection for a protected right turn. 16 Wilston Road Markings and Delineation The old pedestrian crossing near Newmarket train station is reappearing and is clearly visible at all times. There is potential for pedestrians assuming that the crossing is active and thus a risk of pedestrian/vehicle collision. High Consider removal of redundant pedestrian crossing by water blasting. 2 Wilston Road Parking No standing signs are designated for 7am to 6pm. Cars parked on Wilston Road outside these hours will restrict carriageway width and only allow one direction of traffic through causing potential for head on incidents. High Consider establishing no standing arrangements at all times of day. 2 Wilston Road Pedestrians Wheelie bins were observed on the narrow footpath (approximately 1m wide) and obstructing pedestrian movements which are high due to the road being a main thoroughfare for train station passengers. Pedestrians at risk of vehicle collision when forced to walk off the path onto the road. High Consider alternative refuse collection arrangements. Consider increasing warning signs for pedestrians. Consider reducing posted speed of road due to high volume of pedestrians during peak hour. 2 Wilston Road Crash Barriers and Clear Zones The median barrier between Newmarket Road and Erneton Street does appear to be at an appropriate height to prevent vehicles from falling into the opposing lane. Increased risk of injury severity. High Investigate barrier specifications. 2 Wilston Road/Daisy Street Road Alignment and Cross Section Left turn access to and from Wilston Road has limited line marking to indicate priorities and is confusing. Presence of the median island seems to suggest that access is not allowed. Potential for rear end incidents for vehicles accessing Daisy Street from Wilson Road. High Consider extending median prevent vehicle movements to and from Wilston Road. Consider upgrading the intersection in the long term to either eliminate west and north legs or provide a signalised intersection. Wilston Road/Daisy Street Signs Chevron alignment markers (CAMs) located on the median strip are ambiguous and can be viewed as directing vehicles in the incorrect direction (eastbound direction). The bilateral marker used in the median is incorrect for its intended purpose. High Consider redesign of geometric arrangements and signage to improve clarity of permitted movements for all approaches. Wilston Road/Mina Parade Road Alignment and Cross Section Limited sight distance looking to the north at Mina/Wilston. There is an increased risk of angle crashes associated with drivers being unable to see southbound traffic on Wilston Road. This may be improved by relocating the median island on Mina Parade further south to increase sight distance for drivers. High Consider relocating median south. Consider recommendation below regarding signals. 3 Wilston Road/Mina Parade Miscellaneous A high number of right turning vehicles were observed during peak hours from Mina Parade to Wilston Road. Due to the high volume of traffic on Wilston Road and the limited sight distance looking north and south, High Consider a dual signalised intersection which coordinates the Murrell/Wilston Road and Mina Parade/Wilston Road/ Abuklea Road intersections. 3 Wilston Rd Newmarket Rd 81915445 / Final Draft Community Issue of height end and Page 14 Wilston Grange Precinct Study Location RSA Category Transport Engineering Studies Issue/Risk Description RSA Risk RSA Recommendation Crash History Community Issue as well as the four leg intersection, drivers on Mina Parade are likely to attempt to turn with shorter gaps in traffic than would be considered safe for an unsignalised intersection. There is increased risk of angle crashes due to the volume of traffic and restricted sight distances at the intersection. Wilston Road/Murrell Street Road Alignment and Cross Section Sight distance to the north at the Murrell/Wilston Road intersection is limited. Risk of conflict between turning and through traffic at the intersection. High Consider restriction of right turns from Murrell Street (i.e. altogether or during peak periods only). Yarradale Street Road Alignment and Cross Section Sight distance at Progress Parade Days Road is limited. The intersection is a four way off-set intersection with Days Road the priority road. There is a high likelihood of Yarradale Street being used as a north south connection to Wilston Road. Risk of conflicts between turning and through traffic at the intersection. High Consider restriction of right turns at this intersection. 81915445 Final Draft 3 Page 15 Wilston Grange Precinct Study Transport Engineering Studies 6.5.3 Road Safety Audit: Sub – Area 2 While audit findings were recorded for each street/intersection, there were a number of road safety issues that were identified by the auditors as repeatedly occurring precinct wide. These are summarised below: Vegetation overhanging or encroaching within the carriageway; Faded/worn pavement markings; Narrow footpaths or limited of footpaths; Low hanging power lines which cross the carriageway; Inappropriate location of roadside furniture behind road kerb; and Pedestrian network requires improvement. Audit findings, illustrated in Figure 0.3 and summarised in Table 0.4 indicates that the safety issues generally occur along major carrying roads including Days Road, Maygar Street, Thistle Street, Bradshaw Street, Fuller Road and Gilbert Road. In addition to road sections, the intersections of Days Road/Kedron Brook Road, Maygar Street/Brook Street, Archer Street/Montrose Street, Khartoum Street/Thistle Street and Stafford Road/Alva Terrace were identified as areas of concern.

Page 19 Wilston Grange Precinct Study Transport Engineering Studies A similar approach to that adapted for Sub-Area 1, identifying key issues of concern, has been adopted for this area also. There were three specific issues with a risk rating Very High which is listed in Table 0.5. Table 0.5 : Locations Identified with Very High Risk Location Issue/Risk Description Recommendation No stop treatment at intersection of Flower Rd and Maygar Street. There is a risk vehicles will fail to stop and give right of way resulting in a vehicle collision. Maygar Street/ Flower Road Also due to the steep gradient along Flower Road on the approach to the intersection, there is a risk drivers will misinterpret the intersection location and having to apply brakes heavily to stop in time. Failing to stop in time can result in the vehicle travelling onto Maygar Street and colliding with other vehicles. Provide stop line and signage. Also consider providing speed reduction facilities prior to intersection to force drivers to slow down. Maygar Street/ Brook Street Although left turn only sign provided at Brook Street intersecting with Maygar Street, the island arrangement allows sufficient space for vehicles to travel straight. There is a risk drivers will miss the left turn sign and illegally travel straight to other side of road which can result in collision with other vehicles. Observed vehicles travelling straight through across the road. Rearrange island layout to further restrict the through movement. Signalisation of this intersection may be warranted to improve overall safety of all users. Stafford Road/ Richmond Street The pedestrian green walk indicator is not functioning on the south-west corner of the Stafford Road/ Richmond Street intersection. This presents a potential for pedestrians to delay crossing Richmond Street while they determine whether it is safe for them to cross. This could result in a pedestrian commencing crossing when the left turn movement into Richmond Street becomes green causing a pedestrian vehicle collision. Signal repaired. Table 0.6 lists the High risk ratings from the RSA and whether the issue and associated recommendation has a history of recorded crashes and highlighted by the community as an issue. 81915445 Final Draft Page 20 Wilston Grange Precinct Study Transport Engineering Studies Table 0.6 : Key Road Network Related Audit Concerns : Sub-Area 2 LOCATION Beaconsfield Terrace Bedford Street Bradshaw Street Bradshaw Street Bradshaw Street Brook Street Brook Street Chapel Street Days Rd/Maygar Str/Gilbert Rd/Constitution Rd Days Road 81915445 RSA CATEGORY DESCRIPTION RSA RISK RSA RECOMMENDATION Crash barriers and clear zones Railing with a height of approximately 1m is installed along the centre of Beaconsfield Terrace. There is no crash barrier installed at either end of the railings. This creates an impaling risk if a vehicle were to collide with the railing. High Consider removing the fence railing or installing a crash barrier treatment. Crash barriers and clear zones A railing with a height of approximately 1m is installed along the centre of Bedford Street. There is no crash barrier installed at either end of the railing. This creates an impaling risk if a vehicle were to collide with the railing. High Consider removing the fence railing or installing a crash barrier treatment. Crash barriers and clear zones No barrier end treatment provided for approach to bridge. There is a risk vehicles can have a head on collision with the end of the railing and travel over the abutment and bridge. High Consider installation of barrier treatment on bridge approach. 1 Signs and lighting Sight to bike crossing refuge island advisory sign on Bradshaw Street blocked by overgrown trees. There is a risk drivers will not be aware of the refuge island ahead which could result with a collision with a cyclist and or pedestrian. High Consider tree maintenance to remove overhanging tree branches to improve sight to signage or alternatively relocate signage to be located before the tree 1 Crash barriers and clear zones Bridge approach barrier treatment on Bradshaw Street is only protecting the tree behind and not protecting the bridge railing end. There is a risk that the barrier will deflect the vehicle during a collision into the end of the railing. Observed barrier not bolted to vertical support and loose. High Provide appropriate bridge approach barrier treatment 1 Road alignment and cross-section The very sharp crest on Brook Street has limited warning with the road environment conducive to reasonable high speeds over the crest. There is a risk of crashes occurring due to limited sight distance available to driveways or on road obstacles beyond the crest. High Consider installing advisory speed reduction signage. Consider installing traffic calming measures to force drivers to slow significantly through this section. Pavement, Parking Vehicles parked along Brook Street near the intersection of Spear Street greatly reduce the sight distance for vehicles travelling along Brook Street to see vehicles travelling out from Spear Street. There is an increased risk of vehicle to vehicle collisions. High Consider providing yellow line marking to provide no parking zone in vicinity of intersection to provide clear sight distance from Brook Street to Spear Street. Pavement, Parking Vehicles parked along Chapel Street block the sight distance available over the crest for vehicles to safely pass the parked vehicle. There is a risk of a head on collision with oncoming vehicles. High Provide yellow line to delineate no parking zone to increase sight distance Pedestrians and cyclists The zebra crossing at Days Rd / Maygar St roundabout is close to the intersection which caters for relatively high flow of traffic movements. There is a risk of drivers failing to see pedestrians on the crossing until late due to being distracted by negotiating the busy roundabout, resulting in a pedestrian being struck at the crossing. There is a secondary risk of rear end collisions on the roundabouts as drivers brake suddenly to give way to pedestrians on the crossing. High Consider relocating the crossing to be further away from the roundabout and increase visual awareness of the crossing. Crash barriers and clear zones There are numerous trees directly behind kerb on Days Road on the westbound approach to Grange Road intersection. There is a risk of the trees being impacted by traffic on Days Road, particularly by tall vehicles. High Consider tree maintenance to remove overhanging trees/branches over the road Final Draft Crash History Community Issue 1 1 3 Page 21 Wilston Grange Precinct Study LOCATION Fuller Street Gilbert Road Gilbert Road Gilbert Road/ Maygar Street Gordon Street/ Cowper Street Kate Street Khartoum Street/ Thistle Street Lamington Avenue 81915445 Transport Engineering Studies RSA CATEGORY DESCRIPTION RSA RISK RSA RECOMMENDATION Road alignment and cross-section Driveway access along Fuller Road located 10m from Lutwyche Road exiting the petrol station allows vehicles to turn right to travel onto Lutwyche Road. There is a risk vehicles from Lutwyche Road turning into Fuller Street will collide with those vehicles exiting the petrol station. Observed vehicles exiting petrol station and turning right. High Consider closure of driveway from petrol station. 1 Pedestrians and cyclists Inconsistent use of barrier and fencing treatment along Gilbert Road along bridge over Kedron Brook Bikeway. There is a risk that pedestrians can trip and fall over these barriers which can result in serious injury. High Consider replacing barrier with full height fence or barrier to reduce risk of pedestrians falling over edge. 1 Crash barriers and clear zones Bridge approach end treatment located on the approach to the bridge over Kedron Brook Bikeway along Gilbert Road is not flared at the correct angle. There is a risk vehicles can collide with the end and travel over the abutment. High Consider providing a new alignment of barrier to be compliant for bridge approaches. 1 Road alignment and cross-section The shop on the corner of Gilbert Road and Maygar Street has a driveway very close to the roundabout departure leg, with limited visibility. Traffic using the driveway is also required to reverse out into the roundabout to exit the driveway. There is a risk of crash occurring as drivers exit the driveway. High Consider removing this driveway and limit property access to the existing Gilbert Road driveway. Intersections It is difficult at night to see the give way signs and lines on the southbound approach to the Gordon Street/Cowper Street intersection. The pavement markings are hidden by a slight dip in the road and the give way warning and give way signs are obscured. Drivers may fail to perceive the intersection and priority until it is too late to effectively give way, leading to a crash with an adjacent vehicle. High Trim vegetation that is obscuring the give way sign. Consider installing splitter islands at the intersection to increase driver awareness of the intersection. Pavement, Parking Vehicles are allowed to park around tight curve located along Kate Street travelling around to Shamrock Street. A parked vehicle in this location will reduce the lane width and there is a risk that drivers will travel beyond their lane around the tight curve with limited sight distance and collide with oncoming traffic in the opposite direction. High Consider adding yellow solid lane marking to delineate no parking zone around tight curve. Crash barriers and clear zones The power pole located on the corner of Khartoum Street and Thistle Street is very close to the road edge. There is a risk for vehicles to collide with the pole whilst travelling around the tight curve. High Consider relocating the road furniture to increase the setback distance from the kerb; or shoulder lane lines/kerb buildouts to create a separation between the kerb & travel lane; or provide reflective sheeting/markers on poles to increase drivers awareness of pole locations; or installing advisory signage prior; or additional lighting. Pavement, Parking On Lamington Ave at the approach to Bradshaw Street, parking is allowed near the intersection. There is risk vehicles will collide with pedestrians who divert around parked cars to cross the road. Visibility to pedestrian is also restricted by parked vehicles. Vehicles also park across the access ramps. High Consider adding yellow line marking to delineate no parking zone. Final Draft Crash History Community Issue Page 22 Wilston Grange Precinct Study LOCATION Lutwyche Road/ Fuller Street Maygar Street Maygar Street Maygar Street Maygar Street Maygar Street Maygar Street Maygar Street/ Bank Street Maygar Street/ Whish Street 81915445 Transport Engineering Studies RSA CATEGORY DESCRIPTION RSA RISK RSA RECOMMENDATION Signs and lighting There is no signage in the centre median at the intersection of Fuller Street and Lutwyche Road to advise drives of left turn only onto Lutwyche Road. There is a risk drivers are unaware that right turn is banned and try to cross over the road which can result in a head on collision with the traffic on Lutwyche Road. High Consider installation of left turn only sign in centre median to help highlight turning restriction. 8 Pavement, Parking Bus zone along Maygar Street is insufficient length. There is a risk where vehicles are parked just before the bus zone, the bus doesn’t have sufficient space to turn into the bay leaving the rear end of the bus projecting into the through traffic lane. This can result in a vehicle colliding with the bus due to the limited space available. Observed bus pull in and rear end of bus extending into the traffic lane High Consider increasing the length of the bus zone to enable buses to stop fully within the bay 3 Pavement, Parking Parked vehicles along Maygar Street near Brook Street restrict sight distance available for vehicles leaving driveways. There is a risk vehicles will reverse into oncoming traffic resulting in a collision. High Provide yellow line to delineate no parking zone along Maygar Street to improve sight distance 3 Pavement, Parking Parking is currently allowed at the apex of tight corners on Maygar Street. This limits the lane width available at the tight horizontal curves and appears to make the curves more severe. There is an increased risk of crash due to the presence of parked cars at the tight corners. High Consider restricting on street parking at the inside of tight curves along Maygar Street to increase visibility and overall safety. 3 Pedestrians and cyclists There are limited pedestrian connections to cross Maygar Street to access the bus stops and shops from the opposite side of the road. The road carries high traffic numbers and sight distance for pedestrians is limited by the geometry. There is a risk of a pedestrian being struck while attempting to cross the road (particularly difficult between Reid Street and Brook street). High Consider solutions for improving the safety of pedestrian access near bus stops, particularly between Reid St and Brook St. 3 Road alignment and cross-section The length of Maygar Street (from Constitution Road to Lutwyche Road) comprises tight horizontal and vertical geometry. This significantly reduces sight distances available for entering traffic from driveways and side roads. The observed speeds through this section were significantly higher than the posted 40km/hr advisory speed. There is an increased risk of crashes occurring through this section due to the geometry, combined with high traffic numbers. High Consider reviewing speed and sight distance and identify solutions to improve safety with regard to the function of Maygar St in the road hierarchy. 3 Markings and delineation The centre line markings on Maygar Street, particularly through the curves, are worn and difficult to see at night. Drivers may stray onto the wrong side of the road, causing the potential for head-on collisions. High Re-new the centreline markings and consider the installation of additional RRPMs to increase delineation of the road 3 Intersections The sight distance to eastbound traffic on Maygar Street from the Bank Street intersection is very limited by the horizontal and vertical geometry. There is an increased risk of crash occurring as entering traffic fails to effectively give way to through traffic. High Consider turning restrictions at the Bank Street intersection to allow left in – left out only. Crash barriers and clear zones There is a power pole at the bend of Maygar Street / Whish Street intersection which is directly behind kerb on the inside of a tight bend. There is an increased risk of impact to the pole, which is located in a vulnerable position. High Consider treatments to slow drivers through this section and highlight the road geometry. Treatments could consist of a combination of signage, line marking and median build out treatments.

Signalisation of this intersection may be warranted to improve overall safety for pedestrians. 1 Pedestrians and cyclists Very difficult to see oncoming vehicles for pedestrians trying to cross the road to access the bus stop on the other side at Maygar Street and Brook Street intersection. There is a risk pedestrians will not be able to see oncoming vehicles while crossing and potentially be struck by a vehicle. High Consider installation of refuge island at a suitable mid-block location. Signalisation of this intersection may be warranted to improve overall safety for pedestrians. 1 Road alignment and cross-section Due to the crest prior to Brook Street along Maygar Street, there is a risk drivers will not be able to sight a stopped vehicle wanting to turn right into Brook Street resulting in a rear end collision due to limited stopping time for the speed environment. High Consider providing a line marked right turn pocket 1 Pavement, Parking Currently parking is not restricted in the marked shoulder next to the embankment along Maygar Street near Brook Street. There is a risk vehicles will park in the location and cause pedestrians to walk along the road creating a potential conflict with passing vehicles. High Consider providing pathway next to shoulder to allow access to parked vehicles or alternatively provide no parking zone along shoulder. 1 Pedestrians and cyclists The crossing point of the shared user path across Sellheim Street is often obscured by parked vehicles. Pedestrians or cyclists may fail to effectively give way to opposing vehicles. High Consider increasing the length of restricted parking on each side of the crossing point; consider installing kerb build-outs. 1 Signs and lighting Overhanging tree branches blocking sight to guide posts and directional signage around the tight curve along Shamrock Street travelling towards Kate Street. There is a risk that drivers will not be aware of the tight curve until the last minute and travel straight resulting in the vehicle travelling into the park and then over the embankment. High Consider undertaking tree maintenance to remove overhanging branches and installing of CAMs in lieu of directional signage and guide posts to provide increased awareness to drivers Pedestrians and cyclists Pedestrian sight distance at the intersection of Stafford Road and Alva Street is limited by roadside furniture and terrain. This increases the risk of a vehiclepedestrian collision hazard. High Consider providing a pedestrian crossing on Alva Street, away from the intersection to encourage pedestrians to cross at a safer location. Intersections At the intersection of Stafford Road and Brockman Street, there is no protected right turn into Brockman Street. Stafford Road carries a relatively high volume of traffic in an urban speed environment There is an increased risk of rear-end vehicle collisions with vehicles stopped to turn tight from the through lane. High Consider prohibiting the right turn into Brockman Street and separate via a raised central median, alternatively provide a protected turn pocket as part of any upgrade works. Pavement, Parking There is reverse parking along Stafford Road at the corner of Stafford Road and Gamelin Crescent. Stafford Road carries high traffic flows in an urban speed environment. There is a risk of rear-end collisions with vehicles stopping and reversing into parking bays. High Consider revising the southern verge to incorporate these bays into a combined off-street parking arrangement to reduce the risk to drivers accessing parking. RSA CATEGORY DESCRIPTION Pedestrians and cyclists There are limited positions for pedestrians to safely cross Maygar Street near Brook Street. There is a risk pedestrians will cross at a location with limited visibility and increase their risk of being struck by a vehicle. Final Draft Crash History Community Issue 1 Page 24 Wilston Grange Precinct Study LOCATION Stafford Road/ Gordon Street Stafford Road/ Lennon Street Stafford Road/ Lutana Street Stafford Road/ Richmond Street Thistle Street Thistle Street Thistle Street Thistle Street 81915445 Transport Engineering Studies RSA RISK RSA RECOMMENDATION High Consider installation of a pedestrian fence along the median strip with signage directing pedestrians to use signalised intersections to the east/west; or alternatively, install a pedestrian crossing point to provide increased protection and mid crossing storage for pedestrians. High Consider adjusting the signal phasing to protect the right turn into Lennon Street. Alternatively provide a protected turn pocket as part of any upgrade works. Intersections At the intersection of Stafford Road and Lutana Street, there is no protected right turn into Lutana Street. Stafford Road carries a relatively high volume of traffic in an urban speed environment. There is an increased risk of rear-end vehicle collisions with vehicles stopped to turn tight from the through lane. High Consider prohibiting the right turn into Lutana Street and separate via a raised central median, alternatively provide a protected turn pocket as part of any upgrade works. Signs and lighting At the Stafford Road/ Richmond Street intersection a driveway is located on the north side of the intersection. Traffic leaving this driveway is not able to observe traffic phases for movements along Stafford, causing a risk of vehicles leaving the driveway at an unsafe time resulting in potential collision. High Consider installing additional signal heads visible to the driveway. 4 Road alignment and cross-section There is limited sight distance from the driveway along Thistle Street approx. 15m from Gordon street due to the proximity of the crest. There is a risk vehicles travelling along Thistle Street will be unable to sight a vehicle reversing out of the driveway which can result in a rear end collision. High Consider provide an advisory sign advising drivers of concealed driveways ahead along Thistle Street. 1 Signs and lighting There is limited sight distance to the refuge island warning sign for vehicles travelling along Thistle Street towards Gordon Street. There is a risk drivers will miss the sign and having to break heavily once over the crest and possibly colliding with a pedestrian crossing the road. High Consider undertaking tree maintenance to remove offending branches to improve sight distance sign or relocate sign to be located prior to trees. 1 Road alignment and cross-section No cul-de-sac treatment provided to help vehicles negotiate a U-turn. There is a risk vehicles will not be able to do a proper Uturn and be forced to do a 3 point turn. There is also a risk that while vehicles are doing the 3 point turn, a vehicle from Lutwyche Road will turn into Thistle Street resulting in a vehicle collision. High Consider installation of guidance islands for U-Turn to help vehicles navigate around at a safe angle. 1 Road alignment and cross-section There is very limited sight distance available to the driveway located at the end of Thistle Street towards Lutwyche Road for vehicles turning into Thistle Street from Lutwyche Road. There is a risk of a vehicle collision with vehicles pulling out of the driveway. High Consider providing an advisory sign prior to the turn advising drivers of a concealed driveway ahead and removal of planting and shrubs to increase the sight distance available. 1 RSA CATEGORY DESCRIPTION Pedestrians and cyclists There is no easily accessible crossing point within the immediate vicinity of the Stafford Road/ Gordon Street intersection with signalised crossings provided approximately 350m to the east and 250m to the west. A bus stop is located on the north side of Stafford Road and a local store is located on the south side. It is likely pedestrians will attempt cross Stafford Road at this location, which carries relatively high traffic volumes and has a very narrow median. There is an increased risk of pedestrian/vehicle collision. Intersections At the intersection of Stafford Road and Lennon Street, there is no protected right turn into Lennon Street. Stafford Road carries a relatively high volume of traffic in an urban speed environment There is an increased risk of rear-end vehicle collisions occurring with vehicles stopped to turn right from the through lane. Final Draft Crash History Community Issue 3 Page 25 Wilston Grange Precinct Study LOCATION Thistle Street/Huntly Street Tindal Street Victoria Terrace 81915445 Transport Engineering Studies RSA CATEGORY DESCRIPTION RSA RISK RSA RECOMMENDATION Intersections Limited sight distance to vehicles stopping to turn right into Huntly Street from Thistle Street. There is a risk drivers will not be able to see a stopped vehicle whilst travelling over the crest located at the intersection of Montrose Street and Thistle Street. This can result in a rear end collision between vehicles. High Consider banning right turn into Huntly Street and provide no right turn sign. Pavement, Parking Vehicles are allowed to park around tight curve located along Tindal Street travelling around to Kate Street. A parked vehicle in this location will reduce the lane width and there is a risk that drivers will travel beyond their lane around the tight curve with limited sight distance and collide with oncoming traffic in the opposite direction. High Consider adding yellow solid lane marking to delineate no parking zone around tight curve. Crash barriers and clear zones A railing with a height of approximately 1m is installed along the centre of Victoria Terrace. There is no crash barrier installed at either end of the railing. This creates an impaling risk if a vehicle were to collide with the railing. The keep left sign is also located behind the railing and back from the nose of the median, creating a risk of drivers not observing the sign. High Consider removing the fence railing or installing a crash barrier treatment; and move the keep left sign in front of roadside furniture.

Table 0.8 lists locations identified in the RSA where the identified as High. 81915445 Final Draft Page 32 Wilston Grange Precinct Study Transport Engineering Studies Table 0.8 : Key Road Network Related Audit Concerns: Sub-Area 3 Location General Parker Street Green / Cox / Newmarket Lamont Rd / Newmarket Rd Lamont Rd / Newmarket Rd Lamont Rd / Newmarket Rd Victoria / Rosemount / Newmarket 81915445 RSA Category Description Pedestrians & Cyclists Kedron Brook cycleway joins Parker St at both ends of Parker St. The transition between the narrow bike path and on-road conditions for cyclists is not smooth with limited warning generating potential conflicts between cyclists/drivers/pedestrians. Traffic Signals Strong right-turn demand from Newmarket Rd to Green Tce has the potential (and have realised through crash records) for rear-end accidents as there are no dedicated right turn bays and current signal setup shows right-turn red arrow on through green. Road Alignment & Cross Section Vehicles turning right into Lamont Rd from Newmarket Rd must stop in the right hand lane. Drivers travelling on Newmarket Rd stay in the right lane due to parked vehicles on the kerbside lane. This has the potential for rear-end crashes, as indicated in crash records Crash Barriers and Clear Zones Sightline from Lamont Rd into Newmarket Rd disrupted by railway overpass non-transparent anti-throw barrier for approaching vehicles. At stop bar, visibility is favoured by Lamont Rd's location on top of crest on Newmarket Rd. Crash Barriers and Clear Zones Power poles close to kerb creating visibility and potential serious crash issues. Road Alignment & Cross Section Parked cars on kerbside lane of Newmarket Rd limits sightlines and visibility for vehicles turning into Newmarket Rd. Final Draft RSA Risk RSA Recommendation High Consider the widening of the Kedron Brook cycleway path from Enoggera Rd to Parker St. Further consider the provision of sufficient warning and visibility space between motorists and cyclists. Crash Community history Issue - High Consider the revision of the existing signal phasing to allow for strong right-turn movement from Newmarket Rd to Green Tce. 14 High Consider a protected right turn pocket as part of any upgrade works. 10 High Review and consider the installation of sufficiently intersection street lighting and consider the installation of a 'T-Intersection Ahead' sign on Lamont Rd approach. 10 High Consider relocating the road furniture to increase the setback distance from the kerb; or crash barrier guard rail. 10 High Consider left in/left out arrangement or right turn pockets on Newmarket Rd as part of any future upgrade works and parking evaluation. 4 Page 33
