The crossing height limit of highway, railway and waterway bridges is to prevent vehicles and ships from exceeding the height limit and causing collision accidents. The design size of each bridge is different, and the clear height of traffic is also different, so the height of vehicles and ships must be limited. At present, the technical means adopted are setting warning signs for height limit, installing height limit fences, installing height limit detection and early warning devices, and measuring the height of passing vehicles in advance.
