Abstract:

Travellers’ route choice behaviour often has the characteristics of bounded rationality such as regret avoidance under the situation that travel time is uncertain. The intensity of regret caused by the result of choice is closely related to travel habits. In this paper, travellers’ regret avoidance psychology and travel habits are considered simultaneously in the traffic assignment problem. Travellers are classified according to the familiarities of routes between origin-destination pairs. Then, a multi-class stochastic user equilibrium model is established based on the regret theory considering route familiarity. The equivalent variational inequality (VI) is presented, and the solution existence is shown. The result of numerical examples shows that the proportion of users with familiar routes and the difference of their familiarities to each route will significantly affect the equilibrium traffic flow. The new model proposed in this paper can provide theoretical support for travel behaviour analysis, network traffic flow analysis, and traffic control strategy formulation from the perspective of behavioural psychology.
