摘　　要：基于原有的路径关联性模型,综合考虑车辆离散性、阻滞性和局部路网交通流空间特征规律,建立了相邻交叉口间的路径关联性模型,弥补了初始模型仅考虑单一指标的不足;根据路径关联度模型的计算结果,利用聚类分析对信号控制交叉口群进行了动态划分。案例分析和仿真结果表明:协同考虑多重特性因素的路径关联度模型动态划分交叉口群,可以提高区域信号协调控制效果和车辆通行效率。Based on the original path correlation model,considering the discrete vehicle,block and spatial characteristics of local traffic flow,path correlation model between adjacent crosses is established. This model compensates the shortcoming of the original model,which only considers a single index. Based on the calculation results of the path correlation model,signal control intersection groups are dynamically divided using the hierarchical clustering method. Case analysis and simulation results show that the new model of intersection group dynamic division based on signal control protocol can improve the regional Regulation efficiency.
