Research on Travelers' Route Choice Behavior of Travelers Based on Fuzzy Reasoning and Prospect Theory

Travelers' route choice behavior is usually based on analysis of objective information and is explained by expected utility theory. However, less researcher consider information effect on travelers' psychological feelings. In this paper, objective information affecting route choice is firstly analyzed and prospect theory is applied to do psychological mapping of the objective information of route choice contributing factors so as to forming subjective information. Then, the relationship model between the subjective information and evaluation levels is proposed. A BP fuzzy neural network method is designed to simulate relationship model and solve it. Route choice possibility evaluation value is obtained by fuzzy aggregation and defuzzification processing of evaluation levels, which reflects probability of traveler's route choice. Finally, a real network is used to test the validation of this model.
