摘　　要：针对干线协调控制系统中交叉口数量较多,很难获得有效带宽的问题,论文利用可达性指标分析了交叉口的数量对于绿波带宽的影响,提出了基于NV(Non-stop Vehicle)值划分交通控制子区的方法;设计了基于NV值的交通控制子区划分算法;利用VISSIM对一个含有7个交叉口的干线路网进行仿真,仿真结果表明:与干线系统未划分子区相比,本论文提出的方法可提高干线协调系统的运行效率.For the coordinated traffic control system on an arterial with a large number of intersections,it is difficult to achieve an effective bandwidth. This paper developed an accessibility index and analyzed the number of intersections with respect to the progression bandwidth. This paper proposed a method based on NV（non-stop vehicle） values to partition the arterial traffic control system into several subsystems. An empirical analysis was performed on an arterial with seven intersections using VISSIM.Simulation results show that the proposed partition method performs better than without partition.
