Analysis of survey of 800 commuters in the District of Columbia area.

A report is offered on a study of the relative effectiveness of alternative inducements to ridesharing in the Phoenix and Tucson metropolitan areas. The objectives are to provide evidence on the efficacy of a broad range of incentives and to establish a clearly defined methodology for such assessment. The study was conducted in three phases.

Travel Demand Management (TDM) describes a wide range of actions that are geared toward improving the efficiency of travel demand. There is much controversy and speculation as to the strength, role, and validity of TDM solutions. This uncertainty has probably led to misunderstandings of the role and potential of TDM, and therefore, a lower yield from TDM approaches than appears to be possible. This report is the main product of a study that was sponsored by the Federal Highway Administration to try to set the facts straight and provide the most comprehensive, accurate, and useable guidance on TDM. The report provides a set of materials, statistics, guides and tools that should be of significant value in not only increasing the basic understanding of what TDM is, but on how to design and evaluate programs which will deliver the optimal that these strategies can offer.
