To study the process of personnel evacuation at light railway stations, make the personnel evacuation plan and optimize the architectural design, the simulation model and program of personnel evacuation are improved. The stair is treated as a separate space unit and a residual value is used to gather the advantages of grid model and the continuity of occupant’s movement. Through questionnaire surveys and field observations at elevated light railway stations in Chongqing, the passengers’ personal parameters and the response characteristics to fire are obtained. The tested movement speed of people agrees to the empirical data. The process of personnel evacuation and the location of each person at any time are demonstrated dynamically by using the computer-programming Zone Grid Evacuation Simulation Software (ZGESS) on the platform of MATLAB. Meanwhile, the total evacuation time is calculated by the program, and it is the same with the data of observation approximately.
