The invention discloses a highway accident early warning and traffic dispersion system and method. The accident early warning system comprises a rail early warning device which is installed on an isolation fence on the roadside of a highway and can slide along the isolation fence; the rail early warning device comprises a rail clamp matched with the isolation fence, a power module, an image acquisition module, a radar sensing module, a positioning module, a wireless communication module, a warning module ,a central control module and a power supply module; the rail early warning device is installed on the isolation fence through the rail clamp; the central control module is used for performing accident judgment according to the driving speed information acquired by the radar sensing module and the image information acquired by the image acquisition module, and warning or reminding is performed through the warning module when an accident or an accident risk is judged to occur. The system further comprises a projection module used for projecting traffic guidance information to the road surface. The system can be directly installed on isolation fences on the two sides of most roads, and the cost is low; accident early warning or reminding can be carried out so that secondary traffic accidents are avoided.
