【Abstract】 After the characteristics analysis of pedestrian in transportation hub,the social-force based NOMAD model is found to be very suitable for micro-simulation of pedestrian behavior and evaluation of pedestrian facilities.In addition,the hierarchical structure,input conditions and model building ideas of the NOMAD model is proposed.Furthermore,some important parameters are calibrated based on traffic survey data,then the Fuxingmen transfer station is simulated by the model.Based on the simulation results,characteristics of this station are analyzed and some quantization parameters that associate with the transfer system are obtained.By comparing simulation data and observational data,NOMAD model is found to be well adopted to the simulation of pedestrian transfer behavioral characteristics in the transfer hub.The relative error between simulation and observational data is less than 10%.It verifies the validity of applying NOMAD model for pedestrian simulation in transportation hub.更多还原
