摘　　要：分析了传统公交网络配流中忽视公交行驶时间与路段流量的微关联性及公交车的容量限制等方面存在的弊端,提出了用拥挤函数概念描述出行阻抗与流量的关系。结合公交出行时间链对公交网络阻抗进行了系统化研究,建立了基于站点的多路径 容量限制的概率分配模型,并提出了在配流过程中的具体方法和步骤,同时将配流方法与GIS技术相结合进行公交网络配流分析。应用结果表明该方法预测结果与实测值基本吻合,具有较高的准确性和可靠性。Based on analyzing the diminutive relationship of bus running time and link flow, and the limited capacity for bus, the concept of congestion function was proposed to describe the relation of trip resistance and flow, transit network resistance was investigated combined with transit time chain. Then the multi-route probit-based loading model was established, and the algorithm was put forward to achieve a more precise result, the network assignment method was combined with GIS technology. Applied results show that the computation values almost accord with the measure values.
