Highway traffic safety crash cushions

Traffic crash cushions and terminals setting principles :

The layout of the crash cushion should be consistent with the highway route. When it is set at the main diverter end, ramp exit or the front end of the guide island of the toll station, the axis of the anti-collision cushion should overlap the center line of the intersection Angle of the highway route on both sides of the anti-collision cushion, and coordinate with other highway traffic facilities in its location.
