The Research On Influence Of Traffic Distribution By Guiding Information And Route Choice Behavior

The traffic guiding is an effective way to solve the traffic congestion, whose goal is realizing the balanced assignment of traffic flow in the road network through providing guiding information and adjusting traveler's route. The traffic guiding is the suggestion,the traveler may obey the guiding,also may refuse to accept the guiding,different obeying rate will certainly to cause the different route choice behavior, thus causes the different distribution of the traffic flow. Therefore, the guiding information and the traveler's route choice behavior are the two key aspects to affect the distribution of the traffic flow.The purpose of the research is discussing the influence of traffic distribution by the guiding information and the traveler's route choice behavior, providing the theory basis for governor to formulate the guiding strategy, enhance the quality of guiding information and optimize the assignment of traffic flows.The basic principles of the traffic guiding were analyzed, the stackelberg gambling model between the governor and the traveler was established, the traveler route choice decision-making model under the guiding information was established as well. Moreover, the influence models of traffic distribution by the guiding information and the traveler's route choice behavior were established, the models'solution algorithm were designed, and the simulation experiments were designed, the matlab procedure was used to carry on the simulation, the conclusions were drew initially as followings:(1) The guiding information has the remarkable function for balancing traffic distribution. Moreover the function obviously increases along with the traveler's confidence to the guiding information increasing.(2) It is unapt to regard the route's travel time at the equilibrium state as guiding information, the guiding information must be real-time adjusted and be optimized unceasingly in forecast the traveler's response.(3) The guiding information by continual readjustment is quite stable(4) According to governor's goal, any guiding principle is used specifically. While the guiding information is issued by the principle of the system optimization, the system optimization can be realized basically, but some travelers'benefit was sacrificed. While the guiding information is issued by the principle of the user equilibrium, if the travels'response were not considered when issueing guiding information, the user equilibrium can not be realized, if the travelers'response were considered when issueing guiding information, the user equilibrium can be realized basically, furthermore, if the travelers trust the guiding information completely, the coordination of the system optimization and the user equilibrium can be realized.
