The invention discloses a method for predicting the collision situation of left-turn motor vehicles and non-motor vehicles in an intersection. When motor vehicles turn on left turn light to enter a service area, first signal transmitters at the motor vehicles transmit first signals to signal receivers; the signal receivers transmit each first signal to a microcomputer; when non-motor vehicle turnon left turn light to enter a service area, second signal transmitters at the non-motor vehicles transmit second signals to the signal receivers respectively; the signal receivers transmit the secondsignals to the microcomputer; the microcomputer calculates a first position coordinate of each motor vehicle, second position coordinates for non-motor vehicles, determines a non-motor vehicle closestto each motor vehicle and predicts whether the motor vehicles and the nearest non-motor vehicles are about to collide according to the distances between the motor vehicles and the nearest non-motor vehicles, so as to give an alarm to the corresponding motor vehicles and the corresponding non-motor vehicles when the motor vehicles and the nearest non-motor vehicles are about to collide.
本发明公开了一种交叉口内左转机动车与非机动车碰撞情形的预测方法,在机动车开启左转向灯进入服务区域时,机动车处的第一信号发射器向信号接收器发射第一信号,信号接收器将各个第一信号传递给微型计算机,在非机动车开启左转向灯进入服务区域时,非机动车处的第二信号发射器分别向信号接收器发射第二信号,信号接收器将第二信号传递给微型计算机,微型计算机计算各个机动车的第一位置坐标,非机动车的第二位置坐标,确定距离各个机动车最近的非机动车,根据各个机动车与最近的非机动车之间的距离预测各个机动车和最近的非机动车之间是否将要发生碰撞,以便在判定机动车和最近的非机动车之间将要发生碰撞时,分别向相应机动车和非机动车报警。
