Working Width (Road Safety Barrier)
Working Width (Road Safety Barrier) : The minimum width that is required to prevent an impacting design vehicle from colliding with an object behind a road safety barrier system. This includes both the dynamic deflection of the road safety barrier (if any) and the extra width to allow for the roll (vertical rotation) of an impacting vehicle. This ensures that the system width can be accommodated between the deformed road safety barrier and the hazard during impact and that the top of a high heavy vehicle will not impact a high hazard during impact
