Processes and Problems: Developing A
Road Safety Strategy for Lincolnshire
• Casualties on the rural road network are
declining at slower rate than on urban roads
• First steps in the strategy development involved
group discussions to form a list of possible road
safety issues in the County
• List was based on previous experience,
anecdotal evidence and knowledge of the
collisions history in Lincolnshire

•
Key points and problems to overcome:
–
Interrogation of the collision database illustrated
that some issues were not as prevalent are we
first thought:
• The A15 had been trunk road until 2002. At
that time it had a sustained history of collisions
involving vehicles leaving the carriageway
• Collision data from the latest 5 year period
showed this was no longer the case

•
Key points and problems to overcome:
– 74% of Killed or Seriously Injured (KSI)
collisions, in Lincolnshire, occur on the
rural road network (speed limit is greater
than 40mph)
– Even distribution of these collisions across
the County

•
Key points and problems to overcome:
– The RDP in Lincolnshire is not
geographically restricted
– The capital / revenue split required by
the DfT created concern among the
board and partners

Enhanced Verge Maintenance – Why?
• LCC responsible for Verge Maintenance
regime - limits number of cuts each year
• 1.0m cut in verge
• Maintenance of hedges is responsibility
of adjacent land owner
• Vegetation has built up
• LCC and the LRSP receive complaints
from public

Enhanced Verge Maintenance – What?
•
•
•
•
•
Treat two routes: A15 and B1188, both Road
Safety Red Routes (RSRR) which means they
have a higher than average KSI casualty rate)
One additional cut per year
Whole of verge to be cut as opposed to 1.0m
Special attention paid to visibility splays at
junctions, traffic signs and bends
Monitor the effect on collisions and vehicular
speeds

Enhanced Verge Maintenance – Outcome?
• Difficult to ascertain effects of verge
maintenance on contributory factors in
RTCs
•
Speed readings taken before and after the
first cut at three sites along both treated
routes

Enhanced Verge Maintenance – Outcome?
•
On B1188, there are slight increases in 85th
percentile readings

Enhanced Verge Maintenance – Cost?
• For the first cut, including traffic
management, whole verge cuts and any
overhanging trees / hedges:
• Approximately £10,000
• Approximately 25km
• Unsure as to likely financial implications in
relation to cost of an additional cut per
year
