The invention relates to an expressway traffic safety early warning system and method based on vehicle-road cooperation. The system comprises a roadside system, a vehicle-mounted system and a centralcloud platform, wherein the roadside system carries out network connection interaction with traffic infrastructures, and information sharing are formed between the traffic infrastructures and among the traffic infrastructures, vehicles and other traffic participants; the vehicle-mounted system is in butt joint with a vehicle CAN bus and senses the running state of the vehicle, and real-time information interaction is performed between the vehicle-mounted system and the roadside system and between the vehicle-mounted system and other vehicle-mounted systems; and the central cloud platform performs real-time information interaction with the roadside system and the vehicle-mounted system, forms an information interaction channel, stores and analyzes traffic operation data, performs full-time-space tracking on roadside detection information and vehicle uploading information, and provides a data reference for road network traffic state analysis and traffic control measure optimization. By means of a vehicle-road cooperation technology, vehicles on the expressway can travel more safely, and traffic is smoother.
