An Empirical Investigation of the Underlying Behavioral Processes of Trip Chaining

摘要: Trip chaining is a phenomenon that has significant impact on urban transportation and activity systems. This paper argues an appropriate representation of the underlying behavioral processes in models trip crucial to capability reliability models. To examine processes, data complete scheduling were collected with computerized survey instrument, REACT!. The horizons sojourn activities analyzed contingency tables. results this analysis indicate some decision elements entailed opportunistically formed within constraints set by previously planned activities. While engaged earlier activities, individuals might see opportunities carrying out certain at different locations occurring later day. decisions as whether take these or not would depend their evaluation feasibility (e.g., travel time required reach activities). However, also illustrates chains indeed executed planned, suggesting optimality potential routine behavior. Based empirical evidence, transactional opportunistic planning constrained environment viewed model for
