The Research Of Freeway Network Traffic Regulation Based On Expense Function

With the development of society and economy an efficient and scientific traffic network is needed to act as a strong supporter. With the rapid development of economy, the construction of road network, especially the freeway network is extremely urgent. Traffic network is perfect or not have respect to the development of economy and the standard of living. It is the channels of the resource allocation, the link of the balanced development between areas, the connection of the spiritual culture. Our country is in the period to construct affluent society, the development of road network have respect to the development of economy in the future, the perfect construction of highway network is imperative.The purpose of this paper is to solve the problem of the large traffic flow of the freeway network, and the unequal distribute of the traffic flow, tolling system plays an important role in the regulation of the traffic flow to realize the high potency network.According to the idea and the substance of the design theory for mechanism, expounded from the angle of user and the system. Analysis the user's the choice when they face the time, distance and the money. The paper emphasis the tolling system influence the distribution of traffic flow, by using the economic method and controlling the price. Make the tolling system into full play. And thus traffic distribution can be made and freeway resources can be fully used. The paper also looks forward to the traffic regulation.The paper take the traffic situation of Shandong province for example, analyzing the character of traffic flow and network of Shandong province, established the model of the highway network in Shandong province, and confirmed the parameters according to the investigated data. Prove the function of expense has influence on the traffic flow, solve the problem of unequal distribute of the traffic flow, and the freeway network can be fully used.
