摘　　要：通过分析交叉口间距、路段流量、周期比对相邻交叉口关联性的影响,提出量化相邻交叉口关联性的交通度量指标,通过仿真验证了度量指标的合理性,在此基础上进一步提出了网络交叉口群中交叉口之间关联性的计算方法以及相应的网络交叉口群子区域划分的原则。运用该原则进行案例说明,结果证明了其有效性,为以后进行网络交叉口群的交叉口子区域划分的研究提供了一种新的方法。In the operation of urban traffic, intersections play an very important role, and the study for intersection-groups in transportation network is gaining more and more attention. Firstly, by analyzing the im- pact of intersection distance, link volume and cycle ratio on the relevance of adjacent intersections, a new traffic metrics is proposed to describe the relevance of adjacent intersections quantitatively. Then through the simulation method, the quantitative metrics is verified to be reasonable, and furthermore a new calculation method which reflects the relevance of intersections in transportation networks and the corresponding dividing principles of intersection-groups are suggested. A case analysis is conducted to prove the usage of these new principles, which provides a reliable approach to sub-regional division of intersection-groups in transportation network.
