Simulation of Nanjing Metro Line 1 Using Metro Simulator

Based on Nanjing Metro Line 1 (NJML1), this paper presents a metro simulator (MSim). Firstly, NJML1 is analyzed and divided into four subsystems: traction power supply system, track, train, and train controller. The modeling method for each subsystem is presented. Based on the proposed models and Visual Basic 6.0, MSim is developed, which has two operation modes: single-train mode and multi-train mode. Single-train mode is used to check train performances and generate train time schedules. Multi-train mode aims to check and optimize system performances of metro lines. At last, the NJML1 is taken as an example to verify the effectiveness of MSim.
