Abstract:

Travelers often dynamically select their routes since their route choice behaviors are influenced by many uncertain factors in practical travel process. We establish a prospect theory based dynamic route choice model from bounded rationality and change on the way in route choice. We further present a dynamic route choice model more applicable to people thinking habit. It allows a traveler to dynamically adjust the route based on road situation. We also verify its correctness and applicability through practical instances. Results show that a traveler can change route on the way when he meets a congested road section. He will choose a risky route if his psychological expected time cannot be satisfied.

Key words: prospect theory, reference point, bounded rationality, dynamic route choice, change on the way
