Abstract:

With the sustainable growth of urban vehicles’ ownership, it makes the road congestion become an increasingly serious problem. And it is an effective means to solve the urban road congestion by increasing the utilization rate of current road resources through congestion charging. Based on the theory of timespace consumption, the optimal pricing model of multitime road network was established to achieve the maximum social welfare as the destination function and the corresponding algorithm was given in this paper. To the peak period, three different amounts of congestion charges were applied to get the influence on travelers’ travel time. Finally, the algorithm case was analyzed to prove that when the timespace resources are fixed, congestion pricing has a significant effect on regulating the traffic volume distribution during normal periods and peak periods, and reducing the total traffic volume, thus relieving the traffic congestion in urban roads.

Key words: congestion pricing, traffic congestion, time-space resource, social welfare
