3D Simulation for Train Motion of Bangkok Transit System

Today, rail transportation is internationally recognized as the lowest cost per unit of transport, low energy consumption, and less damage to the environment. So far, Thailand is in process to expanding and improvement the modern rail transportation from Bangkok to other city. For this reason, the train system simulation is important for helping to investigate the effects of design and improvement or determine the correctness and efficiency of the design before the system is actually built or reconstructed. Therefore, this paper proposed the 3D simulation model for simulating train motion. we proposed examples use case for Bangkok Transit System (Silom line) in train speed profile simulation. The experimental result shows that the speed between stations is divided 4 part accelerating cruising coasting and braking. The experimental result shows that the speed profile by the 3D simulation model follows the typical stages of a train speed profile. This 3D simulation also can be used for the our open-source full train simulation in future.
