Study On Simulation Of Pedestrian In Urban Rail Transit Station Based On Social Force Model

with Chinese rapid development of Urban Rail Transit, more and more passenger choose Urban Rail Transit for trip, and there are many new problem in Urban Rail Transit Station, so new requirements are made for pedestrian simulation research on Urban Rail Transit Station.The Social Force Model based on Molecular Dynamics is by far the most recognized model of pedestrian dynamics.First of all, This paper introduces the theoretical basis of Social Force Model and calibrates basal date of Social Force Model with walking behavior of passenger in Urban Rail Transit Station, which includes pedestrian types, pedestrian model size, the speed of pedestrians expected for simulation of channel, up and down stairs and platform, the speed of pedestrians crossed for simulation of gate and escalators; secondly, The paper selects and calibrates some important parameters with actual research, verifies the correctness of the previous calibration parameters by comparing pedestrian flow lines and throughput; at last, different transit facilities are simulated by Social Force Model with the previous calibration parameters, so we know throughput's characteristic of different transit facilities, Then simulate the Beijing Chongwen Gate rail transit Station, analyzed the conflict area, evaluate the effect of simulated, optimize a number of rebuild measures, and validate the correctness of the previous rebuild measures by simulation.
