干线协调系统控制子区划分方法

For main line coordinated control system of a large number intersection，difficult to obtain effective bandwidth issues, this paper use accessibility Index and analysis the number of intersections for the impact of Green Wave bandwidth，proposed a method based on NV (non-stop vehicle) values into traffic control sub-system。And on this basis, described based on the NV value of sub-system partitioning step in traffic control in detail。And using VISSIM for the simulation of contains seven intersect- ions for a main line network，Simulation results show that: compared with the traditional sub-system division method，this paper presents the method may further improve the efficiency of the intersection of main line network。
