Question

Why is concrete profile barriers planned with curved surface profiles?

Answer

Safety fencings are designed to include vehicles in carriageway in that they are travelling and prevent them from rebounding into road and causing hazards. For regular fencing design, while vehicles crash into safety fencings, it would give way as a result as to absorb as much energy as possible, thus reducing impact forces on vehicles. Furthermore, it serves to realign vehicles along carriageway at what time vehicles hit on them. Though, for concrete profile barriers they are not designed to absorb energy throughout vehicle crashing, but to hold vehicles hitting on them. In this link, concrete profile barriers are designed with curved profiles as a result that vehicles be able to mount and go up partly on them, yet they will not cause overturning of vehicle
