Research On Train Operation Plan Of Public Transport Intercity Railway

In recent years,with the rapid development of China economy and the acceleration of urbanization,the development of urban agglomeration and economic cooperation and technical exchange is becoming more and more rapid.The formation and development of urban agglomeration and urban economic cooperation and technical exchange bring about the continuous growth of intercity passenger transport demand.Intercity railway has the characteristics of regional,short distance and public transportation,and undertakes the passenger flow service of commuting,trade,communication and other passenger flow services between the main central cities and the urban agglomeration with the big city as the center,which has become an important mode of transportation within the current urban agglomeration.Therefore,the characteristics and travel rules of intercity railway passenger flow are analyzed,and the train operation plan on intercity railway line is optimized and adjusted.In order to meet the travel demand of intercity railway passengers,to improve the operating income of intercity railway and attract passenger flow.The specific research work in this paper is as follows:First of all,this paper analyzes the operation situation and research status of intercity railway public transport,after comparing and studying many references,summarizes the experience of previous research,and carries on the theoretical research to the intercity railway train transit operation plan,mainly includes the content of the intercity railway train operation plan,the formulation principle,the influence factor and the intercity railway transit train operation condition and so on.Then the passenger flow analysis of the train operation plan of intercity railway train is carried out.It mainly analyzes the characteristics and classification of passenger flow in intercity railway,the timing law of passenger flow and the method of dividing passenger flow period.Based on the analysis of the time series of intercity railway passenger flow from three aspects:weekly passenger flow,holiday passenger flow and daily passenger flow,the K-means clustering algorithm is used to divide the high and low peaks of intercity railway passenger flow.Furthermore,a mathematical model for the optimization of intercity railway train operation plan is put forward.The multiobjective programming model with the maximum benefit of railway transportation department and the least general expenditure of passengers is constructed under the constraints of departure frequency,stop times and interval passing capacity.Finally,the theoretical research is applied to the real example.Taking the passenger flow data and line parameters data of Changjiu Intercity Railway as research data for example analysis in this thesis.Using SPSS software to cluster the high and low peaks of the passenger flow period of Changjiu Intercity Railway,using the MATLAB software to write the program,the actual passenger flow data and line parameters are substituted into the optimization model tosolve the optimization model of the intercity railway train operation plan,and make further adjustments to the optimized intercity railway train operation plan.
