Many efforts to evaluate the effectiveness of a transportation demand management (TDM) project focus on either (a) the ability to get information to travelers to have them consider switching to more sustainable modes or (b) the impact of mode changing on travel and air quality. The former type of evaluation is sometimes called soft evaluation (awareness of services offered, inquiries for information, etc.), and the latter is called hard evaluation (trip, vehicle miles of travel, and emission reduction). A large-scale demonstration program funded by the European Commission, called mobility strategies for the next decades (MOST), developed a standardized monitoring and evaluation toolkit (MET) to aid those implementing "mobility management" projects in evaluating all types of impacts and project results. This was achieved by enumerating assessment levels that ranged from awareness to system impacts. The state of the practice in TDM evaluation is discussed; the MOST-MET is introduced; an example of its use with a specific TDM project evaluation is provided; and then the transferability of the MET and its assessment levels to other types of TDM evaluation (beyond pilot projects) is considered.
