Road anti-collision buffer system

The invention relates to a road anti-collision buffer system. The system comprises a collision part, a corrugated pipe part, a buffer part, a controller, an arresting device and a fixed seat, whereinthe collision part is a hollow rubber body, a base of the collision part is connected with the corrugated pipe part, two vent valves are arranged at the bottom of the collision part, the buffer part is arranged in the corrugated pipe part, the upper end of the buffer part is connected with the bottom of the collision part, and the lower end of the buffer part is connected with a fixed seat; the arresting device is arranged on the road surface a plurality of distances away from the collision part, and the controller, the conducting strips and the wires in the rubber body form a loop to controlthe arresting device to turn over. When a vehicle collides, the vehicle sequentially passes through the collision part, the corrugated pipe part, the buffer part and the blocking device, damage of thevehicle to road facilities
