Abstract

This paper proposes a risk-averse user equilibrium (RAUE) model for route choice problem where drivers consider both the travel time and the number of turns/intersections when making their route choices. In this paper, the number of turns/intersections is considered as the route choice factor for drivers to avoid risks and/or accidents for their travel in road networks. Two case studies are used to illustrate the effects on traffic assignment results if drivers consider either the travel time only or both the travel time and the number of turns/intersections for their route choice. The parameters of the RAUE model are calibrated with the use of observed link flow data in Hong Kong study network. The proposed model is also applied to a case study in Beijing and the results are compared with the results of the conventional user equilibrium model. It was found that the proposed model is a generalization of the user equilibrium model, with the conventional user equilibrium model when drivers only consider travel times, being a special case.
