The Study Of Scheduling Optimization Of Bus Based On Rail Transit

:With the rapid development of economy,urbanization and mobilization,the demand of traffic is hardly increased.How to meet traffic demand has become a major challenge urban have to face.Public transportation is more efficiency,and its average energy consumption level is lower.Public transportation become a good choice to Solve traffic congestion.In order to increase the total benefit and meet the diverse needs of passengers.This need for every transportation mode cooperat with eachother efficiently.Firstly,based on the the characteristics of Rail transit and bus transit, analyse the connotation and principle of the transfer coordination between the rail transit and bus transit. And then put forward to the optimization methodology of bus schedule.Secondly,the thesis divided the passengers into three categories:passengers transfer from rail transit to bus transit,passengers transfer from bus transit to rail transit and non-transfer passengers. schedule optimization model of coordinationed rail transit and bus transit is established with the objective function of minimizing the total waiting time of three kind of passengers mentioned before.This model give full consideration to passengers who can't get on the bus and have to wait the next one. Considering the characteristics of the model and the optimization theory,the thesis change the nonlinear model into linear model first and then solve the linear model for the best solution. C language and LINGO are used to complete the algorithm to solve this model.Finally, the thesis analyzed the model and algorithm through experimental method based on basic data from 507th and BMT in Tianjin,and verified the model andalgorithm'general application.
