Path Choice Model Based on Fuzzy Priority Relation

Abstract

Fuzzy phenomena emerge frequently in the process of travel decision-makings. Based on fuzzy priority relation between paths, a new path choice model was provided under assumption of fuzzy user equilibrium. Firstly, after the path with minimal perceived impedance was obtained with mean area method, a choice set of paths was produced by dominance check. Based on the fuzzy priority relation array, priority values of the choice paths were computed, and the choice possibilities of all paths can be obtained. The model can be regarded as a generalization of classical Logit model. On condition that perceived impedance of path is difficult to be described with fuzzy variable, the choice possibility of the path can be obtained by comparing priority relation between a pair of paths with the model.
