Effectiveness of Transportation Control Measures: Overview of the State of the Practice

Report No: 96-TAR3

Published in 1996

About the report:

Transportation control measures, or TCMs, are transportation measures or strategies intended both to reduce vehicle miles of travel (VMT) and to make those traveled more efficient. Although the term TCM has its origins in air quality and emissions reductions, TCMs encompass many of the elements or strategies in transportation systems management (TSM) and transportation demand management (TDM). In practice, overlap among the three concepts is considerable, and the terms TCM, TSM, and TDM are often used interchangeably. The purpose of this report was to provide an overview of the state of the practice regarding the effectiveness of TCMs. Two main areas were investigated: the known effectiveness of TCMs based on case study information, and methodologies available to evaluate their effectiveness. The scope was limited to a literature review, personal contact with state and national professionals involved with TCMs, and a summary and compilation of key existing documentation.
