摘　　要：通过建立公交运行效率评价模型,确定轨道交通沿线待优化线路,为两网融合奠定理论基础。首先通过定性定量法筛选出与轨道交通关联度大且有研究意义公交线路,其次以公交线网自身合理性、两网之间协同关系等数据构建评价体系,最后采用帕累托最优交叉效率模型,求解沿线公交线路运行效率。以南昌市1号线为例,筛选出沿线25条公交线路并进行实证分析。结果表明:帕累托最优交叉效率模型的评分更容易被所有的决策单元(decision-making units,DUMs)接受;数据分析得出南昌公交线网自身合理性较好,但在两网协同关系方面,可优化线路走向、调整线路重复系数等加强其协同性。最后基于两者的帕累托交叉效率均值,将25条公交线路划分为4种案例,为公共交通系统的管理者和决策者提供了更实用和有价值的观点。The establishment of an evaluation model for bus operation efficiency is crucial in determining the bus routes along the rail transit line that require optimization,laying the theoretical foundation for the integration of the two networks.Firstly,a qualitative and quantitative method was used to select bus routes that have a high correlation with the rail transit system and are of research significance.Secondly,an evaluation system was constructed based on the rationality of the bus network itself and the synergy between the two networks.Finally,the Pareto optimal cross-efficiency model was employed to determine the operation efficiency of the bus routes along the rail transit line.Taking the example of Line 1 in Nanchang,25 bus routes along the line were identified and empirically analyzed.The results indicate that the Pareto optimal cross-efficiency models score is more readily accepted by all DMUs(decision-making units).The data analysis reveales that the bus network in Nanchang exhibites good self-rationality.However,in terms of synergy between the two networks,there is room for improvement by optimizing route directions and adjusting route duplication coefficients to enhance their collaborative nature.Finally,this paper is based on the Pareto cross-efficiency mean values of both factors,the 25 bus routes were categorized into four cases,providing practical and valuable insights for the managers and decision-makers of the public transportation system.
