The invention belongs to the field of intelligent traffic, and particularly provides a green wave control method for trunk traffic, which comprises the following steps: determining a green wave control direction according to an average flow ratio of each direction of a trunk; when the green wave control direction is a one-way green wave control direction, the queuing length of the traffic object is used as a phase difference influence factor, and a first absolute phase difference of each group of phase sequences corresponding to each intersection in the one-way green wave control direction is calculated; when the green wave control direction is a bidirectional green wave control direction, determining an absolute phase difference corresponding to one-way green waves of each intersection according to the road length corresponding to each intersection, determining an absolute phase difference range by taking the absolute phase difference as a center, and determining a second absolute phase difference in the absolute phase difference range; and performing trunk line green wave control according to the first absolute phase difference or the second absolute phase difference and the public signal control period. Based on the technical scheme provided by the invention, the arterial traffic can be defibered, so that the congestion degree of the arterial is reduced.
本申请属于智能交通领域,具体提供一种干线交通的绿波控制方法,包括根据干线各方向的平均流量比确定绿波控制方向;当绿波控制方向为单向绿波控制方向时,将交通对象的排队长度作为相位差影响因子,计算各交叉口对应的各组相序在单向绿波控制方向上的第一绝对相位差;当绿波控制方向为双向绿波控制方向时,根据各交叉口对应的道路长度确定各个交叉口单向绿波时对应的绝对相位差,并以绝对相位差为中心,确定一绝对相位差范围,在绝对相位差范围内确定出第二绝对相位差;根据第一绝对相位差或者第二绝对相位差以及公共信控周期,进行干线绿波控制。基于本申请提供的技术方案,可以实现对干线交通的疏解,进而降低干线的拥堵程度。
