Optimization Of Railway Passenger Transfer Scheme Based On Passenger Travel Characteristics

In recent years,my country’s railway network facilities have been continuously improved,and the railway passenger transport business has continued to develop.The high-density railway passenger transport network and high-frequency passenger trains provide convenient conditions for passengers to travel.At the same time,passengers have put forward higher requirements for the transportation services of the railway sector.They expect to obtain safe,economical,fast and convenient transportation services.In the travel process of passengers,transfer phenomenon is inevitable.As passengers do not understand the railway passenger transport network and the connection of trains,it is difficult to plan the route by themselves,or the planned plan is unreasonable.Different passengers have different sensitivity to influencing factors such as cost,time,convenience,etc.,and there will be differences in the connection and transfer plans that are most suitable for them.Therefore,it is difficult for passengers to find the most suitable connection and transfer plan.In order to provide passengers with a connection and transfer plan in line with their own travel characteristics,This paper constructs a continuous transfer network describing the travel process of passengers,establishes a continuous transfer optimization model including a weight function,and conducts research on the optimization problem of railway passenger continuous transfer schemes.(1)Analyze the importance of passenger travel characteristics and optimization of the connection and transfer plan.Divide different passenger groups and analyze the factors that affect passenger travel choices.Define the problem of optimizing the continuous transfer plan,and explain the important role of optimizing the continuous transfer plan from three aspects:improving the service quality of the railway department,providing complete route planning for passengers,and promoting the development of interline transportation.(2)Construct a continuous transfer network that describes the travel process of passengers.Based on the actual line and train operation plan,a continuous transfer network has been constructed.The three influencing factors of cost,time,and convenience are quantified as network parameters,and the transfer convenience is measured by the transfer fatigue recovery time.(3)Establish a continuous transfer optimization model including a weight function.Taking into account the different sensitivity of different passengers to travel costs,travel time,transfer convenience and other travel factors,establish a continuous transfer plan optimization model.Calculate the weight of the three factors in the optimization model of different passengers’ connection and transfer schemes using the principle of analytic hierarchy process,and apply the ant colony algorithm to solve the problem.Finally,a case analysis is carried out,and a connection and transfer plan suitable for different passengers between two pairs of ODs is given,which verifies the rationality of the model and the effectiveness of the algorithm.It shows that the optimized railway passenger transfer plan is beneficial to make up for the shortcomings of the current "continuous transfer" function of 12306.
