The invention provides an intersection signal control method and equipment, and the method comprises the steps: determining a first green light duration of a first signal stage when the first signal stage is used as a release stage, and after a minimum green light duration threshold value is passed, if the first signal stage does not meet a stage early termination condition, determining that the first signal stage does not meet a stage early termination condition; if yes, determining whether the green light duration needs to be prolonged in the first signal stage or not according to the first vehicle density corresponding to the phase of the first signal stage and the first vehicle queuing length and the first waiting release duration corresponding to the phase of each second signal stage when the release ending time from the first signal stage meets a set condition, and if yes, determining that the green light duration needs to be prolonged in the first signal stage; and if yes, updating the first green light duration through at least one preset green light extension duration to obtain a second green light duration. Therefore, according to the scheme, which signal stage is used as the release stage is determined according to the release priority of each signal stage, so that the reasonability of the release sequence, the release times and the release duration of each different signal stage of the intersection can be ensured.

    本申请提供了一种交叉口信号控制方法及设备,该方法包括在第一信号阶段作为放行阶段时,确定第一信号阶段的第一绿灯时长,在经过最小绿灯时长阈值后,若确定第一信号阶段不满足阶段提前终止条件,则在距离第一信号阶段的放行结束时间满足设定条件时,根据第一信号阶段的相位对应的第一车辆密度以及各第二信号阶段的相位对应的各第一车辆排队长度、各第一等待放行时长,确定第一信号阶段是否需要延长绿灯时长,若是,则通过至少一个预设的绿灯延长时长,更新第一绿灯时长,得到第二绿灯时长。如此,该方案通过各信号阶段的放行优先级确定哪一个信号阶段作为放行阶段,可以确保交叉口的各不同信号阶段的放行顺序、放行次数和放行时长的合理性。
