Research On The Integration Of Intercity Railway Train Operation Plan And Working Diagram Compilation

With the increasingly close communication between cities and the gradual improvement of rail transit infrastructure,the traditional intercity railway passenger transport plan compiled by stages is difficult to effectively guide the transportation organization because of its low passenger flow matching and transport capacity resource utilization efficiency.Based on intercity passenger flow dynamics,period of time for the inter-city railway train passenger transport planning integration,can effectively reduce the transport plan of each content in turn set,basic information disconnect,thoughtless constraints,can give full play to the rail transit capacity,reasonable allocation of transport resources,strengthen the passenger travel service quality,reduce the intercity train operations train cost,promote the competitiveness of the intercity trains in the same market in rail transit.The inter-city railway train operation plan and running compiled integration is to solve traditional passenger transport planning in stages,the content of operation plan and running as two separate optimization,to a certain extent,cause each component in the passenger transport plan disjointed,appear the optimized operation scheme in running chart drawing is difficult to implement technical conditions,the optimized running cannot meet the demand of passenger flow,and so on.The main work and achievements of this paper are as follows:1.The introduction part of the inter-city railway train passenger transportation plan,the key analysis in this paper,the operation plan and train running two core content establishment contents,goals,establishment constraint condition,etc.,to take advantage of the technology roadmap generalizes the compilation process,and analysis in this paper,the inter-city train plan running integrated optimization model of necessity and building ideas,build integrated optimization model of total preparation process is put forward.2.Analyzing the operation of collinear intercity trains and cross line of high-speed train and ticketing model difference,build the traffic model,divided into each period based on the characteristics of passenger travel,clustering analysis was carried out on the different period of passenger flow,analysis of traffic and transportation planning interaction and feedback relationships,passenger transport plan passenger flow matching evaluation method,build intercity passenger flow and transportation plan feedback adjustment system.3.Analyze the present situation of intercity transportation planning research and running intercity train plan establishment necessity and key technologies,the introduction of traffic group concept,train carrying in each period the OD passenger flow between groups of state changes reflect the travel needs of passengers,stop using period of difficulty value,quantitative across the line of high-speed train running compiled in the inter-city railway train,the passenger flow and train operation section have been adjusted,then the minimum passenger travel cost and the operation cost as the goal,the construction of the inter-city railway train integrated optimization model of passenger transportation plan.4.Analysis of the inter-city railway stop mode through train and station stopped train special passenger flow characteristics and consider capacity facilities configuration,passenger travel demand,using the method of traditional phased passenger transport planning scheme optimization model of stop,determine the direct train and station in each period the inter-city railway train stop train pairs,using the time stop difficulty values and train special stop mode set to reduce the algorithm search scope,will be stop scheme according to the traditional phased passenger transport planning method to form,compared with integrated optimization model of train diagrams,confirmed that the science and rationality of the model.
