Abstract:

Based on the fact that the area-based congestion pricing may well restrict cars from running into urban centers and park and ride ( P&R) can encourage passengers to choose public transportation without affecting the convenience of driving,this paper establishes a network equilibrium model combining these two schemes which can effectively relieve the traffic congestion in big cities. Then,this model is used to analyze the mixed travel behaviors of cars and buses. Moreover,a modified Gini coefficient is proposed to evaluate the social and spatial equity with the help of the combination measures. Finally,some tests are conducted in the city of Guangzhou,China. The results show that,by using the proposed combination model, the total user benefit is less than that obtained by means of single area-based congestion pricing,while the social and spatial equity is much better,and that,as compared with single P&R,the adoption of the proposed combination model can increase the total user benefit without significant
influence on the social and spatial equity.
