ABSTRACT
This chapter provides a brief overview of past research on travel demand management (TDM) evaluation. It addresses issues surrounding the selection of performance measures for use in TDM evaluation. The chapter outlines monitoring techniques that may be helpful to TDM program managers in developing evaluation procedures appropriate to their needs. It identifies issues associated with the use of TDM evaluation results in decision making. TDM performance measures cover a wide range of experience. Performance measures may vary in terms of geographic exposure, goal orientation, data requirements, and methodological considerations. Congestion management programs come in a variety of forms. Most traffic congestion begins at Street intersections and freeway interchanges. As congestion worsens, traffic delays can extend backwards to include entire travel corridore or even traffic networks. Economie development is only indirectly related to TDM programs in most cases. Where growth is rapid, traffic congestion is more usually the motivating force than its underlying causes.
