The invention provides a right-turn vehicle and straight-going non-motor vehicle track prediction and conflict early warning method. The method comprises the following steps: determining the positions of right-turn motor vehicles and straight-going non-motor vehicles according to signals output by pressure sensors in a right-turn area of a right-turn lane and a right-turn area of a non-motor vehicle lane; the positions of the motor vehicles and the non-motor vehicles are numbered based on the time interval t, and motor vehicle driving information and non-motor vehicle driving information are determined; a random number is introduced into the motor vehicle driving information to update the motor vehicle driving information, the positions of all moments are updated according to the updated motor vehicle driving information and the non-motor vehicle driving information, and the driving tracks of the motor vehicle and the non-motor vehicle are obtained through fitting based on the updated positions; and predicting the time when the motor vehicle and the non-motor vehicle arrive at the potential conflict area based on the driving tracks of the motor vehicle and the non-motor vehicle, determining the difference absolute value of the time when the motor vehicle and the non-motor vehicle arrive at the potential conflict area, determining the conflict level according to the difference absolute value, and carrying out early warning according to the conflict level.
本发明提供的右转车辆与直行非机动车轨迹预测与冲突预警方法,根据右转车道的右转区域以及非机动车道的右转区域的压力传感器输出的信号确定右转机动车以及直行非机动车的位置;基于时间间隔△t对机动车以及非机动车的位置进行编号,确定机动车行车信息以及非机动车行车信息;在机动车行车信息中引入随机数对机动车行车信息进行更新,以更新后的机动车行车信息和非机动车的行车信息更新各时刻的位置,基于更新后的位置拟合得到机动车和非机动车的行驶轨迹;基于机动车和非机动车的行驶轨迹预测机动车和非机动车到达潜在冲突区域的时间,将机动车和非机动车到达潜在冲突区域的时间的差值绝对值,根据差值绝对值确定冲突等级,依据冲突等级进行预警。
