The invention discloses a self-adaptive calculation method of a real-time numerical value of a traffic light intersection segment interval, and relates to the technical field of intelligent transportation. The method comprises the steps of detecting a lane accommodation quantity of vehicles which travel to an intersection along a first direction and a lane accommodation quantity of vehicles whichtravel to the intersection along a second direction, comparing L1 with L2, and according to the comparison result, in combination with the preset green light duration and the preset waiting duration,self-adaptively switching traffic lights, so that the vehicle passing efficiency is higher; detecting the number of the first detained vehicles entering the intersection along the first direction anddetained at the intersection, so that vehicles in two directions are prevented from being detained at the intersection to cause overstock of vehicles at the intersection and serious traffic jam, and the vehicle passing efficiency is higher; and detecting the number of the first detained pedestrians entering a zebra crossing in the first direction and detained on the zebra crossing, so that trafficaccidents caused by the fact that pedestrians are detained on the zebra crossing during traffic light switching and vehicles in the opposite direction drive are avoided, and pedestrian safety is protected.

    本发明公开了一种红绿灯路口分段区间实时数值的自适应计算方法,涉及智能交通技术领域,包括如下步骤:检测沿第一方向向十字路口行驶的车道容纳车量和沿第二方向向十字路口行驶的车道容纳车量,将L1与L2进行比对,根据比对结果并结合预设绿灯时长、预设等待时长,自适应跳转红绿灯的时间,使得车辆通行效率更高;检测沿第一方向进入十字路口并滞留的第一滞留车辆数目,避免导致两个方向的车辆都滞留在十字路口,造成路口车辆积压和严重交通拥堵,使车辆通行效率更高;检测沿第一方向进入斑马线并滞留的第一滞留行人数目,避免有行人在红路灯转换时滞留在斑马线,而相对方向车辆驶来造成交通事故,保护行人安全。
