Simulator design for communication based train control system

The primary function of train control system prevents train collisions by keeping the safe interval with the preceding train. The train control system is consisted of wayside and onboard equipment. The wayside train control system generates control information necessary for train operation, and the onboard train control system controls operational conditions of vehicle and train speeds through information transmitted from the wayside. To improve practical usability in the business area, the safety analysis and evaluation of train control system are needed. In this paper, we design train control simulator for communication based train control system to evaluate the design of train control and operation. The paper presents the simulation configuration, and designed modules and those operations.
