Joint modeling of constrained path enumeration and path choice behavior: a semi-compensatory approach

In this paper a behavioral and modeling framework are proposed for representing route choice from a path set that satisfies travelers’ spatiotemporal constraints. Within the proposed framework, travelers’ master sets are constructed by path generation, consideration sets are delimited according to spatiotemporal constraints, and travelers’ route choices are represented from consideration sets. The paper shows how a semi-compensatory model represents the constrained path enumeration with joint hazard-based and ordered probit models as well as the path choice with a path size correction logit. The results presented in this paper show that spatiotemporal constraints are related to travelers’ socioeconomic characteristics and that path choice is related to minimizing time and avoiding congestion.
