Objective and subjective constraints that trip makers face are analyzed by using a trip-by-trip multivariate unbalanced panel analysis. These constraints emerge from trip makers’ stated reasons and dispositions for why a given mode was not used for their trips. A finite set of behavioral dimensions (situations), which are general, system, and service constraints, lack of information about the modes, negative disposition toward a mode, and time, comfort, and cost considerations were derived from open-ended questions on the respondents’ stated reasons. The presence of these situations, for each trip a person made in a day, is explained in terms of social and economic characteristics of the trip maker, place of residence, household resources, and trip characteristics. As expected, stated reasons for not using a specific mode vary with respect to the mode chosen, and they change within a day in a nonlinear manner depending on a person’s schedule. Illustrated is another facet of unobserved heterogeneity represented in the radically different individual perceptions, which have been recognized as important components in dynamic behavior simulation studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
