Research Of Regional Rail Transit Express Train Plan

With the rapid development of economy, the travel distances of surburban towns and satellite cities residents are gradually becoming longer and longer. Regional rail transit offers travelling service for those residents by its big capacity, less pollution and high speed. Express train is directly related to regional rail transit service quality and passenger travel efficiency. So research of express train operation plan makes a significant difference to the development of regional rail transit.The thesis respectively studies on the operation plans of single train operation route and full-length & short-run route, builds express train strategy program optimazation models based on the analysis of the necessity and feasibility of express train and makes several example tests. The main work and conclusions as follows:(1) This thesis analyzes the necessity and feasibility of express train according to the characteristic and functions of regional rail transit, makes comparation among local train, section cross-site train and express train, concludes that express train is necessary when the length of the route is long, and summarizes the passenger conditions, route conditions and passing conditions;(2) Analyzes the express train strategy program of single train operation route, aimed at maximizing the saving time of all passengers builds express train strategy program optimization model of single train operation route, analyzes the solving process, and takes Wenzhou Regional Rail Transit Line S1 for example, studies on the stop schedule plan, departure frequency and passing stations, and analyzes the effects of the express train strategy program, figures out the stop schedule plan and passing stations, concludes that departure frequency of express train should be 2 pairs per hour, departure frequency of local train should be 16 pairs per hour, the maximum of saving time is 2155844s, the travel efficiency is improved, which means the strategy program meets the passenger demand and has enough idle capacity;(3) Analyzes the express train strategy program of full-length & short-run route, aimed at maximizing the saving time of all passengers builds express train strategy program optimization model of single train operation route, analyzes the solving process, and takes Wenzhou Regional Rail Transit Line S2 for example, studies on the stop schedule plan, departure frequency and passing stations, and analyzes the effects of the express train strategy program, figures out the stop schedule plan and passing stations, concludes that departure frequency of express train should be 4 pairs per hour, departure frequency of local train of full-length route should be 12 pairs per hour, and the departure frequency of local train of full-length route should be 8 pairs per hour, the maximum of saving time is 3943767s, the travel efficiency is improved, which means the strategy program meets the passenger demand and has enough idle capacity.
