Cover Story: Approximately one third of fatal road accidents in Europe occur as a result of collisions and interactions with the roadside infrastructure. To prevent vehicles from leaving the road, roadside restraint systems are installed at the edge of carriageways. A continuous restraint system prevents vehicles from colliding with hazards, thus minimising consequences in the event of a collision. Due to the large variety of such systems, there are always different systems that need to be connected. This is critical, as sometimes a less stiff system needs to be connected to a stiff system. This can lead to vehicle pocketing at the transition of the two systems, increasing the load on the vehicle and its occupants. The challenge is to reduce or even eliminate this pocketing to provide maximum safety for errant vehicles colliding with a road restraint system. View this paper
