During the daily operation of the metro system, unexpected events such as obstruction of doors or medical emergencies will make trains dwell at the platform for a longer time than original timetable, resulting in passengers accumulating, platform crowding and subsequent trains operation being affected. To reduce the impact of interference and to make affected trains resume normal operation as soon as possible, this paper outlines a metro traffic regulation model which reduces the total delay of affected trains and the number of passengers stranded on platforms. Based on Particle Swarm Optimization (PSO) algorithm, a particle Speed-Up and Speed-Down (SUSD) strategy, the crossover and mutation operation of a Genetic Algorithm (GA) are introduced to develop a novel Hybrid Intelligent Algorithm (HIA). In a case study conducted based on real operational data, we have succeed in reducing the stranded passengers by 30% and the total delay by 23% compared with a commonly used fixed regulation method.
