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.
