The invention discloses a road traffic multi-purpose environmental protection guardrail device, which belongs to the technical field of traffic safety. When a vehicle collides with a collision barrier, First, the pressure sensor mounted on the front end of the cylindrical sleeve is subjected to a force, A message is pas to a voice alarming device to alert, reminding pedestrians and vehicles to stay alert, At that same time, the airbag is eject from the through hole and adhered to the surface of the elastic buff layer, reduce the collision damage of the anti-collision railing to the car body surface, At that same time, the movable baffle will slide inward during the impact process, and play a cushioning effect under the action of the strong spring column. Moreover, the cylinder and the piston cushion inside the cylindrical sleeve slow down the hard impact force after the force is applied, and the impact force is released in a slow manner to minimize the damage of the impact to the vehicle personnel and the protective fence.
