The invention relates to a trunk line coordination control method considering the road running speed and the intersection traffic state, and belongs to the technical field of traffic management and control. The method comprises the steps of calculating the signal period duration of each intersection according to the flow and flow direction characteristics of each trunk line intersection, and determining a key intersection and the signal period duration thereof; calculating the minimum effective green light duration of each turning direction of each intersection according to the flow and the key period duration of each intersection in combination with the traffic capacity of an entrance lane; designing and adjusting the phase scheme and signal timing of each intersection according to the key period duration and the minimum effective green light duration of each turning direction of each intersection in combination with staggered release time; and evaluating the phase scheme. According to the characteristics of the flow direction and the flow of the traffic flow at the intersection, reasonable phases are selected, different phase sequence arrangements are carried out, and various signal control schemes can be formed.
本发明涉及一种考虑道路运行速度与交叉口交通状态的干线协调控制方法,属于交通管理与控制技术领域。根据各干线交叉口流量与流向特征,计算各交叉口信号周期时长,确定关键交叉口及其信号周期时长;根据各交叉口的流量与关键周期时长,结合进口车道通行能力,计算各交叉口各转向的最小有效绿灯时长;根据关键周期时长和各交叉口各转向最小有效绿灯时长,并结合错开放行时间,对各交叉口的相位方案以及信号配时进行设计调整;对相位方案进行评价。本发明提供根据交叉口交通流流向与流量的特征,选择合理的相位,进行不同相序安排,即可形成多种多样的信号控制方案。
