Study On Key Problem Of Operation Plan For Sunset-departure And Sunrise-arrival Trains On High-speed Railway

Sunset-departure and Sunrise-arrival Trains on High-speed Railway(Abb.SDSAT-HSR)is a unique brand of high-speed rail transportation in China.Due to its unique transport features and good market reputation,it is now highly regarded.But the Contradiction between train travel and open the maintenance time window(Abb.MTW)of high speed railway has seriously affected the travel of the SDSAT-HSR.As the high-speed line becomes a network,passenger flows increased.It is the inevitable choice and market demand of the development of SDSAT-HSR to reach the networked and the normalization of the train travel.How to adapt to the development of the market,innovating SDSAT-HSR,Optimizing the compile of passenger train plan,coordinating the train travel and maintenance time window,all these are the important issues facing the future development of high-speed railway in the future.The paper started with solving practical problems and was guided by the practice of theory.It took full reference of the operational practice and existing research results and adopted qualitative and quantitative combination,statistical analysis,graphical analysis and mathematical modeling,etc.It studied the problem about SDSAT-HSR and the compile of passenger train plan by using transportation organization,optimization theory,system science,etc.Based on the analysis of the demand characteristics of the passenger flow,the paper puts forward the network and the daily requirement of high-speed railway.As a foothold,on the basis of the analysis of existing operation mode,it put forward periodization SDSAT-HSR.This paper studied the key problems such as the line condition,reasonable distance of the train,and the optimal coordination of the passenger train plan and maintenance time window.The main research of the paper is as follows:(1)There are still many technical problems to be solve continuously about operation mode of Sunset-departure and Sunrise-arrival Trains on High-speed Railway,they are put forward combining actual situation of High-speed railway in China.(2)The SDSAT-HSR operation and MTW setting in nowadays,both here and abroad,are analyzed.The result of operation mode,reasonable driving distance,speed,time domain and maintenance time window settings of SDSAT-HSR are analyzed to summarize the shortcomings of existing research results.Problems and routes of the paper are put forward.(3)Analyze the situation of passenger characteristics,travel rules,passenger sources and their perception of time and price combining the existing data and survey results,passenger characteristics and daily passenger transport demand of SDSAT-HSRcan be got.(4)Competitive relationship among different kinds of train and air flight is analyzed from the aspect of passenger travel options.Passenger flow forecast results of SDSAT-HSRcan be got on the basic of passenger transfer intention calculating.The forecast results shows the network characteristics of Sunset-departure and Sunrise-arrival Trains OD on High-speed Railway.(5)According to the characteristics of China’s high-speed railway integrated maintenance time window and the actual operation of Sunset-departure and Sunrise-arrival Trains on High-Speed,it summarized the current model and type of Sunset-departure and Sunrise-arrival Trains on High-Speed.Combined with the requirement of daily and networking,On the basis of comparing and analyzing existing models,it put forward "Periodization" pattern of Sunset-departure and Sunrise-arrival Trains on High-Speed,and defined the concepts and characteristics of the pattern.(6)The paper analyzed the factors that affect the waiting time and the waiting station selection under "Periodization" pattern and made general Suggestions for the waiting time and the waiting station selection.It has studied the relationship between maintenance time window and the running time of trains,and put forward six types of waiting plans.It summarized the characteristics of different waiting plans,analyzed the ability under the waiting pattern,and gave the suggestions for the design of the waiting pattern.(7)Aimed at "Periodization" pattern,based on the definition and the actual operation situation of Sunset-departure and Sunrise-arrival Trains on High-Speed,it analyzed the speed coefficient and the reasonable departure time domain.Combined with the daily check distance,reasonable time domain,night rest and travel will,and maintenance requirement,it determined reasonable distance of Sunset-departure and Sunrise-arrival Trains on High-Speed,and put forward the the competitive selection model and the solution idea.(8)Divided the network into sections and hubs,based on the Periodization waiting pattern,it built coordination optimization model based on hub and section respectively,taking the Beijing-Guangzhou high-speed railway and Wuhan hubs as an example,it verified the validity of the model and algorithm.The paper used LINGO program to solve the problem.Combined with the graphical method,it came to the conclusion that MTW plan for seven days cycle under the waiting pattern was both better than the current "4+3" model of the Beijing-Guangzhou high-speed railway in two aspects of maintenance and train operation.Combined with the operation time of China High-speed railway,the contradiction between sunset-departure and sun-rise arrival High-speed rail trains’ operation and maintenance had been solved by the “Cyclical and waiting” mode.Meanwhile the new thinking about the sunset-departure and sun-rise arrival High-speed rail trains’ operation plan had been proposed.The Technical support and theoretical reference of the daily operation of the sunset-departure and sun-rise arrival trains on China High-speed railway had been provide through this paper.
