Research On A Game Process Of Urban Trsport Mode Under Carsharing

The application of car sharing mode can relieve the two problems of traffic system in nowadays.One is traffic congestion and the other is air pollution. Car sharing has been introduced in some of China’s big and medium-sized cities as other countries are doing this actively. Beacause the features of travelling by car sharing make low fitness of the existing model, this document does meaningful research based on game theory and analysis of car sharing. In this rearch, the influence of trip mode which is consisted of public transportation and private cars when car sharing is applied is studied further.For the rearch of car sharing and public tarnsportaion mode, our document created a new public transportaion mode that contains car sharing based game theory. Firstly, the number of people who could choose any way to travel was determined under the balance of requirement.Secondly, three strategies of single cycle game and their profits are analyzed according to the thought of competitive game, so are the six strategies of multicycle game and the profits. Then profits calculation methods of cooperative game was analyzed. At last, profits calculation methods of half cooperation and half competition game in the urban passenger transportation market is discussed.This document does research on influencing process of car sharing and private cars based on evolutionary game theory. A game model of car sharing and private cars was created by considering travel behavior choice of people, participation in the management of government and the cost of people because of inconvenience when the car sharing was chosen too much. By parameter analysis of replicator dynamics, a method that could make a benign development of the transportation system was proposed.The model feasibility was verified by data simulation. In the case of car sharing and public tarnsportaion were introduced, the number of travel under the balance of requirement and profits of the way to travel under the cooperative competition game were calculated. Then the problem of which way to travel under what kind of strategy could get the biggest profit was discussed. In the case of car sharing and private car game model, evolutiomary stability graphs of different evolutionary stable state were shown. This document provides theoretical basis for development of car sharing and relevant policy.
