摘　　要：路网容量是制约火车站发展的重要因素,为确保城市道路网络的有效利用,火车站客流规模应与路网容量协调发展。基于路网容量约束下,预测火车站到发客流、周边用地诱发客流及换乘客流。该预测模型以3类客流规模总和最大为目标函数,以城市道路各路段容量为约束条件,分析火车站枢纽衔接交通方式分担率,将火车站枢纽客流按照用户均衡方法加载到城市道路网络中进行迭代检验。以兰州西站作为实例,验证算法的可行性并给出合适的预测客流规模。As an important factor, urban road network limits railway station hub＇s scale. To ensure the efficient op- eration of road network, the scale of hub passenger flow should be properly adapted to the road network capacity. This paper forecasts the maximum scale of railway station hub passenger flow under constraint of urban road network capacity. The forecast model＇s objective function is to maximize the sum of all passenger flows and under the limit of road network capacities on all links, and further to determine the share ratio of all access modes of railway station hub. Then, the OD traffic is assigned to road network with user equilibrium method. Finally, a case of Lanzhou Western Railway Station is used to verify the effectiveness of model and algorithm and to suggest the proper scale of passenger flow.
