The Department of Transport and Main Roads (DTMR) are currently investigating developing the capability within DTMR to implement an integrated land use transport model, with the ability to test different land use scenarios in response to key infrastructure projects, such as Cross River Rail. This proposed framework and subsequent model would give DTMR the ability to influence land use planning from both a state and local government perspective to better utilise and account for changes in the future transport network capacity. This model would also greatly improve the relationship and linkages between transport and land use planning.

Transport infrastructure investment decisions are made with the help of transport model outputs. However, contemporary transport models focus extensively on day-to-day decisions at various levels of aggregation, and generally use macroeconomic projections of population, residential location and activity locations as exogenous. That is, the relations between population projections, long-term decisions (e.g., residential location, workplace location, car ownership) and mobility decisions (e.g., mode and route choices) are generally ignored in their endogenous nature. In particular, the behavioural dimensions of the decision-making processes by populations are not currently fully accounted for.

For example, highly congested urban networks likely influence household residential location choice, and household composition growth probably affects both residential location, workforce participation and mobility decisions. Model outputs are affected by the shortcoming of ignoring the endogenous nature of these relations and are likely unrealistic in their predictions. These have consequences in the allocation of resources, planning environments and funding priorities. In addition, given future mobility solutions that are likely to change the concept of commute, it becomes even more relevant to consider more integrated dynamic models.

This project will be conducted over a three-year time frame and will comprise of three interlinked stages:

Stage 1 will be concerned with the compilation of a knowledge base capturing international best practice that will inform Stage 2.

Stage 2 will develop an integrated land use and transport modelling framework.

Stage 3 will be to implement and operationalise a prototype model in an SEQ context.

The overarching aim of this research will be to assemble a new modelling framework with the capacity to analyse and model population-land use and transport interactions. The case study context for this project is the South East Queensland region.
