Research on modeling and simulation of vehicle-on-board Automatic Train Protection subsystem of Communication Based Train Control system

Communication Based Train Control (CBTC) system is the most advanced train control system in the world nowadays. How to model and simulate the system to find the design defects in the research and development has became one of the key issues of CBTC research. This paper describes a method of developing the hierarchy system model and refined modular model of Vehicle-on-board Automatic Train Protection (V-ATP) subsystem of CBTC system using Colored Petri Net (CPN). The aim is to provide a simulation environment for the research and development of V-ATP subsystem.
