摘要

Traditional modeling and simulation in research and practice have already moved to encompass a wide variety of dimensions of trip makers' everyday life. Key aspects of this move include behavioral dynamics of life cycle stage transitions, repetition and cycles in time allocation and travel over weeklong periods, day-to-day variation in activity participation and travel, considerable attention to duration of activities and travel as well as departure time choice, and tour and trip chain considerations and associated decision making. As a result, many policies can now be analyzed through use of a new generation of models. A new need, however, arises for models that incorporate how people perceive space and time and how the use of imperfect information impacts travel choices. New models are also needed to (a) assess the affects of new technologies, (b) evaluate information systems for travelers, (c) assess processing and financing scenarios, and (d) analyze combinations of transportation management strategies. All mis means an increasingly pressing need for new models mat surpass current options. Existing data collection efforts are no longer sufficient to estimate these models, which require more and different data.
