摘　　要：经典绿波协调控制适用于交叉口及路段流量相似且路口数量较少的情形,无法适应现在复杂交通情景.基于绿波带宽和关联度对城市干道进行子区划分,将拥堵和畅通路段分段进行绿波控制,并利用集合运算的方法建立控制模型协调相邻分段绿波.以此来对不同交通特征路段和交叉口实施不同特性绿波控制,达到精准化绿波控制.以桂林市中山路为例进行VISSIM仿真,结果表明:该分段绿波协调控制模型与经典绿波控制模型相比能显著降低系统延误时间和停车次数,提高了整体交通服务水平.Classical green wave coordinated control is suitable for the situation where the traffic flow at intersections and road sections is similar and the number of intersections is small.But it can’t adapt to the complex traffic situation now.Based on the green wave bandwidth and correlation degree,the urban trunk roads were divided into sub-areas,and the congested and unblocked road sections were controlled by green waves.The control model was established to coordinate the green waves of adjacent sections by using the set operation method.In this way,the green wave control with different characteristics can be implemented for different road sections and intersections with different traffic characteristics,so as to achieve accurate green wave control.Taking Zhongshan Road in Guilin as an example,VISSIM simulation shows that the segmented green wave coordinated control model can significantly reduce the system delay time and parking times compared with the classical green wave control model,and improve the overall traffic service level.
