Probability of Vehicle Collision with a Road Safety Barrier
PublikacjaA well-designed and constructed road allows the driver to avoid encroachments into an area with obstacles in the road environment and to return safely to the carriageway. This is possible when there is an obstacle-free zone in the road environment or, in the absence of an obstacle-free zone, when a road safety barrier is used. This paper discusses the probability of a vehicle hitting a road safety barrier, assuming five sequences...
