To establish a framework for the online planning system METRIX, the Sustainability Unit of the New South Wales Department of Planning commissioned the Transport and Population Data Centre (TPDC) to develop a Sydney VKT regression model. The aim was firstly to identify the factors that impact on car usage, and secondly, to develop a quantitative model to predict the vehicle kilometres travelled (VKT) likely to be generated given a set of socio-economic, locational and urban form characteristics. The model will be used to inform land use planning by predicting VKT resulting from proposed developments enabling their assessment against the metro strategy objective of reducing growth in VKT. In addition, the model can be applied to gauge the impacts of various development scenarios at a broader sub-regional level. This paper describes the development of the Sydney VKT regression model. It begins with a brief review of literature for results and procedures of related studies. The following section presents the model and explains what it means. Section 4 describes the development process. Subsequent sections discuss the limitations, the validation procedure and scope for further work.
