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.

This manual suggests a process for TDM development and implementation, and offers guidance on the selection of effective TDM strategies. It provides an overview of the "big picture" of TDM planning, then guides you in identifying what strategies make sense for you, and in determining how much of those strategies you need to achieve a desired or required trip reduction.

This publication brings together an international group of researchers and presents work from different countries dealing with issues related to transport policy, attitudes and mode choice, car sharing and alternative modes of transport, and discusses the future of non-motorized modes of transport.
