Research on subway trains´ energy conservation running based on PSO

Railway transit service is now the major transportation means in urban public transit system, fixed section running time is the main merit. Meanwhile, metro takes the most part of energy consumption in urban public transit system. How to improve the energy utilization rate is the technical problem to hinder the development of it. Combined with the actual vehicle line sections of Nanjing Metro Line 2, make use of PSO to optimize vehicle´s operation model with timing-energy conservation strategy, compare with the result of GA, the results demonstrate that PSO meet the request of timed energy conservation optimization.
