According to the intersection traffic signal control method disclosed by the invention, the state of the current phase is detected according to the released duration of the current phase, the phase switching point decision is made based on the state of the current phase, and the phase duration planning decision is made based on the decision result of the phase switching point decision. Whether phase switching is carried out or not is determined according to the planning duration planned by the phase duration planning decision and the state to which the current phase belongs, in the decision making process, decision making is carried out with the sum of the set phase parking utility as a target function, and the parking utility is used for representing the total number of vehicles in the phase; obtaining the traffic flow information according to the traffic flow information in two adjacent phases at the intersection. According to the invention, corresponding traffic signal control is carried out by combining the decision results of the phase duration planning decision and the phase switching point decision, so that the risk of decision errors caused by a single decision is reduced; decision is made by taking the sum of the parking utility as the objective function, so that the decision result is global, and the number of parking times is reduced.
本申请公开的交叉口交通信号控制方法,根据当前相位已放行时长,检测当前相位所属状态,并基于当前相位所属状态,进行相位切换点决策,基于相位切换点决策的决策结果,进行相位时长规划决策,并根据相位时长规划决策所规划的规划时长、当前相位所属状态,确定是否进行相位切换,在决策过程中,以设定相位停车效用的总和为目标函数进行决策,所述停车效用用于表征相位内车辆总数,根据交叉口处两相邻相位内的车流量信息得到。本申请结合相位时长规划决策、和相位切换点决策的决策结果来进行相应的交通信号控制,减少了单一决策所导致的决策失误的风险;通过以设停车效用的总和为目标函数进行决策,使得决策结果具有全局性,有利于减少停车次数。
