9.0 Strategic Model Development
Strategic modelling for the study area was undertaken using the Brisbane Strategic
Transport Model (BSTM) Multi Modal v1.2 (modified PIP) for weekday morning, weekday
evening conditions in 2013 (base case) and 2031 (Do Minimum) scenarios.
The model was revised and updated to reflect network changes that have occurred since the
original 2011 version of the model was developed, and to improve the level of detail in the
study area. This included disaggregation of a number of zones.
Detailed SATURN Simulation Models were developed for the study area and surrounds to
investigate road network performance in further detail. Morning and afternoon peak hour
models for base and future years were developed. These models provide a useful tool for
investigating the effects of congestion on the major road network and the implications that
this might have on the study area. The models were also used to identify intersections that
reach capacity and amendments that need to be made to intersection geometry to cater for
predicted future demands.
Cordoned trip demand matrices were produced from the revised strategic model for use in
developing the calibrated base and future year peak hour SATURN Models. The BSTM was
primarily used for determining travel growth targets, and the external travel demand inputs
for the local area SATURN simulation Model. The BSTM was also used to determine the
potential wider changes in route choice associated with any network changes in the study
area.
The following sections outline in further detail the process used and assumptions made for
developing the road network models. Demographics used in the BSTM were also revised to
reflect current conditions and future planning intent. The model development process is
summarised further in Table 0.1.

9.1 Future Option Development
All the future option networks were developed based on the calibrated 2013 models with
planned future transport infrastructure projects added. Table 0.2 lists the future projects
schemes that have been included in the future models in different years.
9.2 Future Infrastructure Projects
Table 0.2 lists the planned future transport infrastructure projects in the vicinity of the study
area. The future models of 2031 contained all the listed schemes below. This has been
further illustrated in Error! Reference source not found..
