Parallel Simulation of High-speed Trains Using Ray-based Cloud Computing

Train operation simulation of high-speed railways is an important part to ensure safety and efficiency. With the development of high-speed railways, there exist a lot of train operation data to be processed, and the calculation speed requirements for simulation prediction are increasing. To meet the requirements of big data processing and real-time simulation of high-speed railways, the idea of parallel computing is introduced into train operation simulation and cloud computing is employed to improve the speed of train operation simulation. The parallel simulation algorithm of high-speed trains is established based on the moving-block system through the Ray distributed computing framework. The calculation time of parallel simulation is significantly less than that of serial simulation. It can reduce the train operation simulation and prediction time, facilitate timely adjustment of train operation plans, and ensure safe train operation.
