Random Equilibrium Assignment With The Integration Of Road Toll

With the acceleration of urbanism in our country, the city population increases rapidly and traffic grows simultaneously, thus the traffic demand expands greatly, which can not be met by the capacity increased by building new roads or upgrading exiting ones. So it is very necessary to manage demand when expanding the capacity. Congestion pricing as one of the tools of demand management is effective to alleviate the traffic congestion.As we know, demand management is essentially influencing people's traffic decision by taking some action, and the traffic decision not only involves road choice, mode choice, but also destination choice. There are many destinations in the urban traffic network, their attraction is rather different owing to their fame, people's habit etc, some is quite congested while others are opposite. A congestion pricing model based on SUE and multi-destination choice was developed to decide the reasonable pricing level to lower their attraction, thus the traffic flow can be allocated statuesquely and the traffic facility can be used effectively. The paper includes the following chapters:The first chapter puts forward the concerned problems and gives a general account of the content and its significance.The second chapter introduces the concept, classification, and the reason of congestion pricing. It also involves the theory structure of congestion pricing, pointing out the shortcomings of traditional congestion pricing theory.The third chapter introduces the basic theory of traffic flow assignment, including UE and SUE, discussing the conditions of SUE with multi-destination choice.The forth chapter establishes the bi-level model based on SUE and destination choice.The fifth chapter gives an example.The sixth chapter gives a conclusion and puts forward the further direction in this field.
