The invention provides an urban road network trunk green wave line automatic generation and calculation method, and relates to the field of urban traffic signal coordination control. Comprising the following steps: (1) establishing an urban road network intersection topological relation; (2) determining an intersection with the maximum traffic demand; (3) generating forward and reverse green wave lines; (4) fusing the forward and reverse green wave lines; according to the method for automatically generating the green wave line, firstly, the intersection with the largest traffic demand is determined, the intersection serves as a search starting point, the correlation degree between the intersection and the adjacent intersection is calculated, green wave line search is carried out according to the correlation between the intersections, manual participation is not needed in the whole process, and the green wave line is automatically generated; the subjective influence of technicians can be reduced, and the efficiency and scientificity of green wave line determination are further improved. By means of the method, the coordination control scheme of the networked intersections in the urban area can be optimized, and the travel experience of residents is greatly improved.

    本发明提供一种城市路网干线绿波线路自动生成与计算的方法,涉及城市交通信号协调控制领域。包括以下步骤:(1)建立城市路网交叉口拓扑关系,(2)确定交通需求最大的交叉口,(3)正、反向绿波线路生成,(4)正、反向绿波线路融合,(5)0点绿波首尾融合。现发明了一种自动生成绿波线路的方法,首先确定交通需求最大的交叉口,以该交叉口为搜索起点,计算与之相邻交叉口的关联度,根据路口间的相关性来进行绿波线路搜索,整个过程不需要人工参与,自动生成绿波线路,可降低技术人员主观影响,进一步提高绿波线路确定的效率和科学性。通过该方法,可实现城区内联网路口协调控制方案最优化,大大提升居民的出行体验。
