Austroads commissioned a study to establish a nationally consistent approach to evaluating the effectiveness of travel demand management (TDM) measures with a particular emphasis on non-pricing measures. The study aimed to provide a basis for more informed choices between non-infrastructure and infrastructure solutions, a better understanding of how and when to use TDM measures and to enable TDM investment decisions to be considered and integrated with other investment choices. This paper draws on the research undertaken for Austroads to outline a framework for the evaluation of TDM measures. As will be explained, there is a distinction between appraisal and evaluation, and since the former has received much less attention in the context of TDM, that is the emphasis of this paper.
