The invention relates to a bus priority adaptive signal control method and system. The method comprises the following steps: a vehicle-mounted electronic tag device on a bus sends a bus priority request to a roadside unit device; the edge computing device obtains sensing data of the sensing device and light state phase data of the signal machine in real time, analyzes and judges whether the current environment of the intersection supports a signal priority request or not, and reports the signal priority request to the road side unit device when supporting the signal priority request; when the bus priority request and the signal priority request are received at the same time, it is judged that the bus priority request can be executed and sent to the annunciator; and the signal machine automatically dispatches the remaining seconds of the current traffic light according to the remaining time of the current traffic light and the predicted remaining time of the bus arriving at the intersection, so that the bus passes through the intersection preferentially. According to the scheme, a request execution signal priority phase does not conflict with a current intersection passing phase, and the bus priority scheme is adaptively executed according to the intersection traffic general situation.

    本申请涉及一种公交优先自适应信号控制方法及系统。所述方法包括:公交车上的车载电子标签设备向路侧单元设备发出公交优先请求;边缘计算设备实时获取感知设备的感知数据以及信号机的灯态相位数据,并分析判断路口当前环境是否支持信号优先请求,在支持信号优先请求时向所述路侧单元设备上报信号优先请求;在同时接收到所述公交优先请求和所述信号优先请求时,判断为可执行公交优先请求并发送至所述信号机;所述信号机根据当前红绿灯的剩余时间和该公交车预计到达路口的剩余时间,自动调度当前红绿灯的剩余秒数,使公交车优先通过路口。本方案不受请求执行信号优先相位与当前路口通行相位冲突,根据路口交通概况自适应执行公交优先方案。
