Crowded Road Pricing Issues

For several decades growth of traffic volumes has outstripped investments in road infrastructure. The result has been a relentless increase in traffic congestion. Severe road congestion not only can take much inconvenience to people' s life, and also restrict the development of economics, deteriorate the environment and etc. So how to solve the road congestion problem is a big challenge that the transportation authority has to face. And more and more people realize that it could not solve the problem only through expanding capacity by building new roads or upgrading existing ones. Congestion pricing as one of the tools of demand management is effective to alleviate the traffic congestion.This dissertation is focusing on the research of congestion pricing, establishing the bi-level programming model involving mode choice and route stochastic choice. The chapters are as follows:The first chapter puts forward the concerned problems and gives a general account of the content and the significance.The second chapter introduces the concept, classifies the congestion pricing in two different ways and analyzes the reason of congestion pricing.The third chapter introduces the theory structure of congestion pricing, points out the shortcomings of the traditional congestion pricing theory.The forth chapter introduces the basic theory of transportation flow assignment as the foundation of the bi-level model, which is established in the chapter five.The fifth chapter establishes the bi-level model involving mode choice and route stochastic choice, which is used to find a good price strategy.The sixth chapter concludes the whole dissertation and points out the further research directions in this field.
