摘　　要：城市轨道交通客流分配是进行轨道交通线网规划、评估和运营管理的关键技术之一。考虑有效路径之间重叠对路径选择概率的影响,在效用函数中加入路径尺度调整效用值,提出基于路径尺度的Logit客流分配方法。以北京地铁线网为例,构建乘客出行广义费用函数,搜索有效路径,清洗自动售检票系统(automatic fare collection,AFC)刷卡数据,通过MATLAB软件进行客流分配计算。结果表明:与既有模型相比,路径尺度Logit模型路径选择概率误差降低了24.32%,提高了客流分配精度。提出的路径尺度Logit模型具有较好的适用性、有效性,对于提升城市轨道交通线网科学规划水平、降低运营安全风险具有重要意义。Passenger flow assignment is one of the key technologies for planning,evaluating,operating and management of urban rail transit network.Considering the influence of the overlap between effective paths on the path selection probability,a path-scale Logit model was proposed by adding the path-scale adjustment utility value to the utility function.Taking Beijing Subway as an example,a generalized passenger travel cost function was constructed.After searching for effective paths and cleaning automatic fare collection(AFC)data,passenger flow distribution was calculated by MATLAB software.The results show that compared with the existing models,the path selection probability error of the path-scale Logit model is reduced by 24.32%,and the passenger flow assignment accuracy is improved.The path-scale Logit model has good applicability and validity,which is of great significance to improve the scientific planning level and reduce the operational safety risk of urban rail transit network.
