中文摘要：
首先分析了传统基于路段进行关联度计算模型的局限，在此基础上，建立了综合考虑交叉口信号相位、路径流量不均匀性、交叉口间距和交叉口排队的路径关联度模型．针对2个实际的信号控制交叉口，进行了关联度计算和协调控制关键路径判断的算例分析；对比研究了本文模型与路段关联度模型的性能，分析了交叉口间距、排队、车道数和信号相位等对交叉口路径关联度的影响．算例分析结果表明，提出的路径关联度模型能更确切地描述交叉口问的关联性，并能够准确判定交叉口间协调控制的关键路径．
英文摘要：
An analysis was first made of the shortcomings of traditional link-based incidence degree model. Then a routebased incidence model was built by taking the factors into consideration such as the intersection distance, the signal phases, route volume distribution and queue at approaches. Finally,a case study was made of the two intersections. A comparative study was made of the performance of traditional link-based incidence model and the proposed route-based incidence model. The impacts of intersection distance, queues, number of lanes and number of signal phases were analyzed. The results show that the proposed route-based incidence model can descript the real relationship of adjunct intersections and find the key route for signal coordination.
