Optimization Of Train Operation Plan For Intercity Dedicated Passenger Line Based On Passenger Flow Dynamic Allocation

Intercity dedicated passenger line services short distance passenger transportation among adjacent cities or in city groups, which is an important means of transportation in closely linked and coordinated development among major cities and major towns. Its advantages are large capacity, mass transit and high-speed. It will play a key role in passenger flow circulate for the provincial capital cities, large cities and major towns. Residents in high income level regions need fast, punctual, comfortable transportation, and intercity trains can provide them with high quality transportation services.With the development and improvement of the intercity dedicated passenger line network, the transportation organization of existing railway is no longer adapted to the new railway network operation. In order to increase the passenger flow sharing rate, and improve the quality of passenger transportation service, the train operation plan of intercity dedicated passenger line is optimized to reduce the passenger travel cost. The passenger flow dynamic allocation is a dynamic way to select a different grade train according to the train stop plan, the departure time, arrival time and the interval running time. According to the objective equation and constraint equation, the optimal train operation plan is obtained. The main contents of this thesis are as follows:(1) This thesis summarizes the prediction method of trend passenger flow, transfer passenger flow and induce passenger flow. On the basis of summarizing and using the research results of the mutual influence between the passenger train plan and passenger flow both China and abroad, and Chinese characters of intercity passenger flow, the thesis discusses the relationship of cyclic feedback between the passenger flow and the train operation plan.(2) Firstly, the dynamic allocation model of the intercity dedicated passenger line passenger flow is constructed. Based on the dynamic allocation model, the passenger train operation plan optimization model is constructed, and the objective of the model is the minimal sum of passenger interval running time and waiting time, and the constraint is the minimal departure time difference and the maximum passing capacity.(3) This thesis surveys and analyzes the present situation of the passenger transportation passageway, traffic transportation structure, passenger flow condition along the Guangqing intercity dedicated passenger line. According to the characteristics of passenger flow section, formulated the stop plan of the intercity passenger trains as nonstop, only stop on one main station and stop on every stations three categories. This thesis uses ideal point method and MATLAB programming to solve the optimization model of Guangqing intercity passenger train. The results show that Guangqing intercity line should operate 8 nonstop trains,21 trains stop on one main station and 16 trains stop on every stations.
