Research On Optimization Of Train Operation Planning Considering Passenger Traveling Efficiency

In recent years,the high-speed railway network has been developing and expanding,and for people,it becomes more frequently to travel with high speed train.Improving the service level of railway passenger transport enterprise and improving the efficiency of the traveler travel efficiency has become a new direction for the continuous development of enterprises with the high-speed train favored by people.Passenger travel efficiency is determined by travel distance and travel time.The travel distance cannot be changed.The only way to improve travel efficiency is to reduce the travel time.This study pays attention on reducing the train origination time and the waiting time caused by passenger travel preference time.A questionnaire was handed out to study the passengers' preference on travel time.In order to ensure the importance of nodes among railway network,analytic hierarchy process(AHP)was used to calculate the importance of nodes and analyze calculation results on node hierarchical level.Based on the goal of benefit maximization for both passengers and the enterprise,the train operating planning was built and also genetic algorithm(GA)was used to calculate the model.The main research questions of the current study are:(1)According to the definition of passenger travel efficiency and based on the each part of the time that the passengers used for travelling,a questionnaire was designed…After analyzing the questionnaire,the proportion of each preferential time was collected andthe passenger convenience curve was given to reflect the passenger travel convenience of each time period.(2)Based on the definition and the factors that influence of the train running scheme,In order to determine the starting point of the train operation section,the city where the station is located is used as a node to evaluate its importance.Then a node importance evaluation index system is put forward and the degree of node importance in the road network is calculated by using the analytic hierarchy process.For the aspect of train running,the methods for determining the two road networks are discussed separately.Then the advantages and disadvantages of the two passenger transport modes are compared and analyzed,and the content of the cross-line passenger direct transport mode is considered.(3)The researcher combined the passengers' time consumption and expenses of travelling as general travelling cost to analyze enterprise cost of railway operation.Set the minimum of passengers' general travelling cost and railway operation's enterprise cost as purpose to build optimization model of train running scheme,and then use GA to resolve the model.(4)Taking the Wuhan-Guangzhou high-speed railway line as an example to verify the model and algorithm established and by using the same way to calculate the importance of nodes and then determine the train operation section.The OD passenger flow data is divided into passenger flow at each time zone according to passenger convenience curve by using models and calculations to resolve the train running scheme.
