摘　　要：随着城市轨道交通线网规模不断扩大,乘客的出行路径选择日益多样,城市轨道交通运营也由单一主体向多运营主体发展。这些变化都对清分收益和客流精准性提出更高的要求。文章以武汉市轨道交通线网为研究对象,通过对既有清分模型进行适用性分析,并结合乘客出行行为调查数据,深入探讨换乘便利性、路径迂回因素以及环形线路如何影响乘客路径的选择。研究提出一种迂回路径的识别方法,优化清分模型中有效路径筛选规则,并通过构造换乘便利性函数、迂回因子函数优化路径效用计算方法。最后通过起讫点(OD)算例进行模型适用性对比分析,结果表明优化模型具有更高的精准性。As the urban rail transit network continues to expand,passengers'choices for travel routes are becoming increasingly diverse,and rail transit operations are evolving from single operators to multiple operators.These changes are imposing higher requirements on fare collection revenue and passenger flow accuracy.This article takes the Wuhan rail transit network as the research subject,and through the applicability analysis of the existing clearing and sharing model,and combined with passenger travel behavior survey data,it carries out an in-depth discussion on how transfer convenience,detour factors,and circular routes affect passengers'route choices.The research proposes a method for identifying circuitous paths,optimizes the effective path screening rules in the clearing and sharing model,and optimizes the path utility calculation method by formulating a transfer convenience function and circuitousness factor function.Finally,a comparative analysis of the applicability of the model is conducted through an origin-destination(OD)calculation example,and the results show that the optimized model has a higher accuracy.
