Research On Optimization Of Train Operation Scheme Of Danda Intercity Passenger Dedicated Line

Inter-city passenger dedicated line is a universal form of passenger transportation,which undertakes the task of passenger transportation among major cities and central cities along the line.Reasonable planning of the operation mode of inter-city passenger dedicated lines can effectively enhance services of the passenger and improve the competitive edge of dedicated passenger routes between cities.Train operation plan plays an important role in the railway passenger transportation organization.It reflects whether the existing railway infrastructure and technical equipment can be reasonably used,and directly affects the train operation,comprehensive connection,train types,train pairs,direction and so on.、In order to discuss the interaction between passenger travel and travel modes,this paper first analyzes the research status of intercity railway operation schemes at home and abroad,and then analyzes the influencing factors and compilation principles of railway operation schemes according to the current actual situation.Through analyse of the present passenger flow statistics in Danda City,it is analyzed from six aspects: the overall passenger flow law,the monthly sending volume and the weekly fluctuation law.Through analyzing the passenger flow characteristics of inter-city passenger dedicated lines,the passenger flow forecast is made from three aspects: trend passenger flow,transfer passenger flow and induced passenger flow.After analyzing the interaction between train operation mode and passenger travel mode,this paper puts forward a dynamic passenger allocation model based on train operation mode,which takes the maximization of railway revenue and the minimization of total passenger expenditure as constraints and uses genetic algorithm to solve it.Through solving the operation scheme of Dan-Da intercity railway,the operation scheme of this line and the corresponding optimized passenger flow matrix are obtained,and the simulation comparison proves the effectiveness of this method.
