Abstract

With the development of social economy, the problems of urban traffic has become increasingly prominent. It is necessary to pay attention to the traffic planning. Traffic assignment is an important content of traffic planning. The route choice of the traveler is the focus of traffic assignment. In the study of route selection, the most commonly used method is Logit route choice. However, in the macro-level road network, Logit route choice method has the problems of exhaustive path and complicated calculation process. The road network in the urban center belongs to the meso-level road network and the traffic characteristics are more consistent. It is of significance to investigate the traffic assignment in the urban center by using Logit route choice method. In this paper, based on the framework of the optimal path evaluation index system, the method of Analytic Hierarchy Process (AHP) is proposed to improve the calculation method of path flow in traditional Logit route choice. First, according to the influence of the road hierarchy on the route choice, the road impedance function with the road hierarchy consideration is established. Then, the method of calculating the flow distribution rate in traditional Logit route choice is improved by using the road resistance function of city center area previously established, and the traffic assignment method of the urban central area is constructed by combining the successive equilibrium algorithms in the multi-path allocation method. Finally, the case analysis of Zone F traffic flow distribution is carried out, and the more reasonable distribution result is found out. The results provide a scientific basis for the management and planning of the traffic department.
