摘　　要：在分析交通枢纽内行人交通特性的基础上,探讨了基于社会力原理的NOMAD模型的分层结构、输入条件以及模型构建思路,指出其非常适于进行交通枢纽内行人行为微观仿真以及行人设施评价.根据交通调查数据对NOMAD行人仿真模型的参数进行了标定,利用标定后的NOMAD模型对复兴门换乘枢纽建立仿真模型,分析了该枢纽的性能特点,获得了与换乘系统相关的量化参数,通过仿真数据与观测数据的对比分析可知,利用NOMAD模型能很好地模拟所研究的换乘枢纽内行人换乘行为特性,模型模拟结果与实际观测数据之间的相对误差均在10%以内,验证了NOMAD模型应用于交通枢纽行人仿真的有效性.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.
