The rails that stop cars from going of the highway are insignificant. They are made of metal, will cause more damage to your car, and don’t completely stop a car from flying off the road. The solution is here; Roller Rails are basically rails with plastic wheels on them that stop your car from flying off the road with less damage and increased safety. When cars crash into the rubber wheels, the wheels spin; pushing the car along and absorbing most of the impact. Here’s what it looks like.
So far, roller rails have been installed on highways in parts of Europe and Asia.
Roller rails are an example of civil engineering. Anything that has to do with roads, buildings, and other structures are considered civil engineering.
