DISAGGREGATE BEHAVIORAL MODELS OF TRAVEL DECISIONS OTHER THAN MODE CHOICE: A REVIEW AND CONTRIBUTION TO SPATIAL CHOICE THEORY

In recent years, considerable effort has been spent on the disaggregate, behavioral modeling of travel dicisions. Much work has centered on intraurban mode-choice decisions and on home-based person trips for work purposes. Disaggregation has been accomplished by a focus on the travel behavior of individuals or of subgroups of the urban population; subgroups are defined by either socioeconomic characteristics or class of residential location. Preliminary attempts to incorporate more realistic assumptions about human behavior in traditional models have led to probabilistic approaches and to the a priori specification of perceived time, comfort, safety, convenience, and other variables as factors influencing mode choice. Attention is now being paid to the measurement of the disaggregate, behavioral modeling of intraurban travel by: (1) collating and reviewing literature to assist with decisions other than mode-choice applications in the trip generation, trip distribution, and route assignment phases of current transportation planning; (2) focusing attention on the importance and salient features of spatial choice models in these contexts, particularly destination choice models for shopping, recreational, and social trips; and (3) outlining research problems and strategies.
