The Simulation Platform Of Express-Local Train In Urban Rail Transit

Train timetable schedules are efficient and stable of the basic requirements for train operation in Urban-Rail-Transit. Schedules are usually based on station data which takes a lot of time and effort by the researchers to draw. In the rapid development of Urban-Rail-Transit, the traditional transportation organizational mode has been unable to satisfy. Many cities in China began to do research about a new transportation organization mode which called express-local train organizational mode. Express-local train organizational mode must traverse station to find the suitable station as the over-taking station. Then the trains simulated running process according to the train timetable schedule.This paper described express-local train running environment and platform from the angle of system function, designed the main interface of express-local train running platform. The main interface described dynamic information of signaling equipment and express-local train. This paper designed the signal equipment status, studied on train running simulation algorithm in accordance with the timetable, key researched express-local train. This paper described the detailed design of train positioning algorithm, interlock algorithm and over-taking algorithm.This paper elaborated’express-local train’running environment and platform from the angle of the software. Achieved the graphical interface for the software and completed train simulated running process based on train timetable schedule. In order to simplify operation, programmed automatic test tools and to explained the statistical data of code process.In this paper, the project was based on the TTE (time-table-editor). TTE generated the train diagram of traditional mode and Express-local train organizational mode. The train was running according to the train diagram. Before the researchers planning the design and construction of the lines, the software simulation was expected to provide a preliminary validation of the theoretical study and to test the express-local train diagram. In this paper, the actual data Chengdu No.18 line as a data source, with some reference value.
