The invention discloses a single-lane vehicle meeting safety analysis method based on the Internet of Vehicles, and relates to the technical field of intelligent traffic, and the method comprises the steps: collecting original data, and transmitting the original data to a roadside edge calculation unit; dividing the original data into a forward driving vehicle data set and a reverse driving vehicle data set according to the driving direction by using a roadside edge calculation unit, establishing a trajectory prediction model according to an improved Kalman filtering algorithm, predicting the driving trajectory and the longitudinal distance value of two vehicles driving in opposite directions, and calculating a minimum safe meeting distance threshold value; judging the longitudinal spacing value and the minimum safe meeting distance threshold value, and sending a meeting risk coefficient to an Internet of Vehicles road test board; and receiving the meeting risk coefficient through an Internet of Vehicles road test board, converting the meeting risk coefficient into an acousto-optic early warning signal, and sending meeting risk early warning information to the vehicle by using a roadside edge calculation unit. According to the invention, through data acquisition, dynamic risk assessment and diversified early warning mechanisms, the vehicle meeting safety is improved.

    本发明公开了一种基于车联网的单车道会车安全分析方法,涉及智能交通技术领域,包括采集原始数据,并传输至路侧边缘计算单元;利用路侧边缘计算单元将原始数据按照行驶方向区分为正向行驶车辆数据组和反向行驶车辆数据组,并根据改进的卡尔曼滤波算法建立轨迹预测模型,对相向而行的两车进行行驶轨迹和纵向间距值预测,计算最小安全会车距离阈值;将纵向间距值和最小安全会车距离阈值进行判断,将会车风险系数发送至车联网路测板;通过车联网路测板接收会车风险系数并转化为声光预警信号,并利用路侧边缘计算单元向车辆发送会车风险预警信息。本发明通过数据采集、动态化的风险评估和多样化的预警机制,提高会车安全性。
