The invention discloses a traffic risk sensing system based on a sparse point detector, and belongs to the field of traffic intelligent systems. Comprising a traffic information acquisition module based on a roadside detector, a traffic information acquisition module based on a vehicle-mounted detector, a vehicle-mounted traffic information data analysis module, a road section traffic information data analysis module, a data transmission module and a road section traffic risk analysis module. According to the traffic risk sensing method based on the sparse point detector, under the condition that the coverage rate of the roadside detector is low and the permeability of the vehicle-mounted detector is low, the roadside detector and the vehicle-mounted detector are used for collecting real-time track data of part of road sections, part of vehicles and surrounding vehicles, and the traffic risk sensing method is based on discontinuous vehicle position information. The global traffic operation risk is judged, and the problem that the global traffic operation risk state cannot be obtained in the traffic environment that the roadside traffic sensor and the intelligent network connection vehicle are low in permeability in the intelligent network connection environment is solved.

    一种基于稀疏点检测器的交通风险感知系统,属于交通智能系统领域,包括基于路侧检测器的交通信息采集模块、基于车载检测器的交通信息采集模块、车载交通信息数据分析模块、路段交通信息数据分析模块、数据传输模块、路段交通风险分析模块。本发明方法基于稀疏点检测器的交通风险感知系统,在路侧检测器覆盖率较低及车载检测器渗透率较低的情况下,利用路侧检测器及车载检测器采集部分路段及部分车辆及周围车辆实时轨迹数据,基于不连续的车辆位置信息,对全域交通运行风险进行判断,解决了智能网联环境下路侧交通传感器及智能网联车渗透率较低交通环境下,无法获取全域交通运行风险状态的问题。
