The invention discloses a road traffic safety risk assessment system based on a traffic conflict technology, and relates to the technical field of traffic safety. The system comprises a track identification and preprocessing module, a risk assessment module and a risk early warning module. The track identification and preprocessing module comprises a radar, used for collecting instantaneous coordinates of the vehicle in a fixed coordinate system and used for capturing license plate information of the vehicle and identifying the length li of the vehicle; a computer and a storage device, used for recording instantaneous coordinates belonging to each vehicle in an acquisition time period and range as a track sequence (time-coordinate sequence) and calculating motion parameters of the vehicle, an output end of the risk assessment module is connected with a risk early warning module, and the risk early warning module judges a result according to the severity of the risk. A corresponding acousto-optic signal is sent out through the early warning prompting facility to warn a driver, and then real-time monitoring, assessment and prevention of workshop conflict risks are achieved.
本发明公开了一种基于交通冲突技术的道路行车安全风险评估系统,涉及交通安全技术领域,包括轨迹识别及预处理模块、风险评估模块和风险预警模块,所述轨迹识别及预处理模块包括:雷达,用于采集车辆在固定坐标系下的瞬时坐标视频摄像头,用于捕捉车辆的车牌照信息并识别车辆长度li;计算机及存储设备,用于将采集时段及范围内属于每辆车的瞬时坐标记录为轨迹序列(时间‑坐标序列),并计算出车辆的运动参数,所述风险评估模块的输出端连接有风险预警模块,所述风险预警模块根据风险严重程度判定结果,通过预警提示设施发出对应的声光信号给予司机警告,进而实现了对车间冲突风险的实时监测、评估与预防。
