The invention belongs to the field of vehicle-road cooperation self-driven sensing, and particularly relates to an intelligent road network medium for vehicle-road cooperation triboelectricity self-driven sensing. Comprising an embedded high-elasticity triboelectric self-driven sensing unit (1), a grating type middle interlayer (2), an upper steel base plate (301), a lower steel base plate (302), a steel strut and spring (303), cushioning foam (4), a high-strength flexible nano-modified caulking layer (5) and a high-strength high-toughness waterproof packaging layer (6). The embedded high-elastic triboelectricity self-driven sensing unit (1) is prepared by selecting two flexible materials with remarkable electronegativity difference according to triboelectrification and electrostatic induction effects. The method is suitable for sensing vehicle and road information such as road average speed, vehicle weight, road surface state and the like, and the sensing range is 10-120km/h of vehicle speed, 2-20t of vehicle weight and 0.35-0.8 of road surface friction coefficient. Compared with the prior art, the method has the advantages of multiple sensing information, wide sensing range, high sensing precision, high sensing network coverage rate and the like.
