	Summary:
	Exits on multilevel interchange ramps present potentially dangerous spots from the point of traffic safety. Therefore, a range of vehicle restraint systems was developed to reduce the consequences of traffic accidents. Proper installation of adequate crash cushion systems requires sufficient space (length) at the point where the ramp leaves major road. To provide for an installation of such a system, the basic geometry of the exit ramp must be reconsidered, introducing the appropriate ration between the radius and transition curve.
