The invention discloses a method for identifying traffic conflicts in a roundabout based on curve driving behavior characteristics, which relates to the technical field of intelligent traffic management and comprises the following steps: acquiring channelization data and vehicle video information of the roundabout; accurately positioning the positions of the target vehicle and the adjacent vehicle to obtain motion information; each future movement track is predicted, the TTC of the target vehicle and the adjacent vehicle at any moment is calculated, and when the TTC value is lower than a set safety threshold value, the system judges that a conflict risk exists; vehicle conflict analysis and early warning at the annular intersection can be realized, a driver is reminded in time, and rear-end collision is avoided.
本发明公开了一种基于曲线驾驶行为特征的环形交叉口内交通冲突识别方法,涉及智能交通管理的技术领域,包括获取交叉口渠化数据、车辆视频信息;精确定位目标车辆及相邻车辆位置,获得运动信息;预测各自未来运动轨迹,计算任意时刻目标车辆与相邻车辆的TTC,当TTC值低于设定的安全阈值,系统将判定存在冲突风险;能够实现在环形路口的车辆冲突分析、预警,及时提醒驾驶人,避免造成追尾。
