Crash cushion is a device that can stop the vehicle safely and change the driving direction of the vehicle to avoid serious injuries to passengers by absorbing the collision energy of the vehicle. Its main function is to reduce the severity of the accident. On the other hand, it also plays a warning and inducing role through its surface color and graphic symbols.

Kinetic energy principle anti-collision pad is generally composed of the end, energy absorbing material, both sides of the beam,diaphragm and back support. After a vehicle collides with the anti-collision pad, it absorbs the energy of the colliding vehicle through the deformation of the end part and energy absorbing material, and the back support is used to resist the impact force of the vehicle.
Energy absorbing material is generally foam material or rubber material, the principle of the anti-collision pad for the front and side of the vehicle has a good effect of energy absorption and guidance, and the system after the collision, the main components can be reused, convenient and fast maintenance and low cost, the disadvantage is a little more complex and high cost of the initial installation.
The principle of momentum conservation is generally composed of sand filling or water filling anti-collision cylinders (piers) of different masses arranged in a certain order. After a vehicle colliding with the anti-collision cushion, the momentum of the vehicle is transferred to the anti-collision cylinder in turn, which reduces the speed of the vehicle and the anti-collision cylinder in turn, and finally makes the speed of the vehicle lower than 15km/h.

Traffic crash cushions and terminals setting principles:
1. If the roadside guardrail is located within the width of the net highway area without safety treatment, the upstream end of it shall be equipped with crash cushions or anti-crash terminals.
2. Directed crash cushions should be installed at the main diversion end, ramp diversion end, tunnel entrance and other
positions of the expressway. If the tunnel entrance and the outside guardrails have been handled by guardrail transition, the crash cushions may not be installed.
3. The beginning of the central guardrail of the first-class highway, and the middle pier end of the bridge that crosses the
expressway, should be equipped with directed crash cushions .
4. The front end the guide island in the toll station can be provided with non-directed crash cushions.
5. If there are special forms of dangerous obstacles within the width of the calculated net zone on the highway side and no other means of safety and effective protection can be adopted, directed crash cushions and non-directed crash cushions should be set.

It has a guiding anti-collision cushion structure with the protection level reaching TS, TA and TB, and its safety performance meets the requirements of the Highway Guardrail Safety Performance Evaluation Standard (JTG B05-01 -- 2013). It can be applied to the main diversion terminal, ramp diversion terminal, tunnel entrance, middle pier end of the bridge, toll island, front end of special obstacles and upstream end of some roadside guardrail, etc.

The guide cushion and guardrail standard section have smooth transition connection, which meets the requirements of standard specification.
It has an efficient stage-by-stage buffering and energy-absorbing structure, which has been verified by the collision test of real cars. It has a large safety reserve and high safety performance. Modular design, easy to install, energy absorption components can be partially replaced, low maintenance cost.
