Research On Urban Road Congestion Pricing Based On The Overall Road Network Effects

With the development of economic, urbanization process accelerated and the growth of travel demand and ownership of motor vehicle, urban road congestion has been restricting the development of the city. The limited resources of the city and layout have limited the size of the road construction. The urban road congestion pricing is an urban transport demand management measure. Scientifically solution to congestion pricing is the issue of one of the effective potential methods.Based on the conclusion of congestion pricing theory both at home and abroad and foreign cities of research results in practice the effectiveness of congestion pricing, the paper researches on urban road congestion pricing based on the overall road network effects. Discriminate and define urban road congestion, elaborate the causes of congestion and the negative impact to society as a whole; In the view of economic, analyzes the road congestion pricing noting that the ultimate goal, the four the course goals of road congestion pricing and the basic form of the five charges. Elaborate the affecting factors of the implementation of road congestion pricing and put forward the timing of the implementation and the principles. Research the marginal external costs of congestion based on the overall road network and give the quantitative calculations. In accordance with a variety of quality of service level in the real road network structure, on the one hand, need to meet the transport demands of different types, on the other hand, network traffic should operate efficiently. According to it, set up the path marginal cost pricing model in order to achieve the maximization of resource sharing. Give the services pricing in two forms: the use pricing and hold pricing, differences and connections between service pricing and the congestion pricing . Research congestion pricing in the light of the services pricing, proposing M-bids. It is important to analyze the effect of road network. The paper puts forwards three calculation methods of congestion pricing based on the effects of network, carries out the comparative analysis of different levels for the methods and suggests that congestion pricing should take full account of network effects for the dynamic and intelligent pricing and avoiding the network congestion spillover to seriously consider the proposed pricing and that the implementation whether is reasonable pricing. The research methodology and the corresponding conclusions the paper presents can provide the important theoretical basis for the congestion pricing.
