The invention relates to a track data-driven highway thrown object detection and avoidance early warning method, which belongs to the technical field of traffic intelligent perception, and is characterized in that a traffic data acquisition module is used for acquiring highway vehicle position information in real time by using a non-visual sensor, and a data processing module is used for carrying out side end processing on vehicle track data; the data transmission module sends side end processing data to the cloud end, the thrown object judgment module is responsible for judging the position of a thrown object according to track characteristics, and the variable speed limit information issuing module issues position information of the thrown object to a road user through an RSU. The highway thrown object detection and avoidance early warning method provided by the invention gets rid of the dependence of thrown object detection on a visual sensor by using the vehicle real-time trajectory data obtained by the non-visual sensor, and realizes thrown object judgment and position estimation from the statistical sense by using the vehicle trajectory data, so that the accuracy of the thrown object detection and avoidance early warning is improved. The problems of low precision and high false alarm rate of traditional thrown object detection are solved. The method has the advantages of being capable of being copied and popularized and high in robustness.
