The invention provides an airport scene traffic signal timing method, system and device under A-SMGCS control and a medium. The method comprises the following steps: determining a monitoring range, screening traffic bodies passing through an intersection, and determining traffic priorities of conflicting traffic bodies; acquiring the current traffic body speed in real time, and predicting an occupation time window of each traffic body to the intersection; obtaining a dynamic stop line position of the traffic body with low traffic priority according to the traffic priority, the geometric size and the predicted occupied time window information of the conflicting traffic body; setting a safety decision point, and determining an initial signal timing scheme according to the traffic priority and the conflict information of the traffic body; judging whether the traffic body can safely pass through the intersection in the initial signal timing scheme, updating the signal timing according to the judgment information, and guiding the traffic body to a safety decision point through the speed; and when a safety decision point is reached, whether the intersection can be passed is judged again, final signal timing is obtained, and different speed guide strategies are adopted to a stop line or pass through the intersection according to a timing scheme.

    本发明提供A‑SMGCS控制下机场场面交通信号配时方法、系统、设备及介质,包括以下步骤:确定监测范围,筛选经过交叉口的交通体,确定冲突交通体的通行优先级;实时获取当前交通体速度,预测各个交通体对交叉口的占用时间窗;根据冲突交通体的通行优先级、几何尺寸和预测占用时间窗信息,得到通行优先级低的交通体动态的停止线位置;设置安全决策点,并根据交通体的通行优先级和冲突信息确定初始信号配时方案;判断交通体能否在初始信号配时方案内安全通过交叉口,根据判断信息更新信号配时,并通过速度引导交通体至安全决策点;达到安全决策点时再次判断能否通过交叉口,得到最终信号配时,根据配时方案采取不同的速度引导策略至停止线或通过交叉口。
