Although various specifications all put forward the requirements of measures such as setting a height limiting protective frame, a reasonable and effective structural form is not provided. The existing height-limiting protection frame is mostly of a fixed rigid structure, and when an ultrahigh vehicle is not parked in time, the upper structure of the ultrahigh vehicle is cut off, so that the problem of passenger accidents is easily caused. The causes of accidents are mainly classified into the following two categories:

Due to the fact that the collision mechanism research on the protective frame and the ultrahigh vehicle is insufficient, the design of the protective frame is lack of scientific guidance, the protective frame possibly has unreasonable structure, the improvement and the perfection of the structure cannot be achieved, the protective frame only plays a warning role, and a good protective effect is not achieved when collision really occurs. Meanwhile, the collision easily causes the damage of the upright post and the foundation, which may lead to the integral overturn of the height-limiting protective frame and the secondary damage.
In addition, the overweight wagon causes serious damage to the bridge of important traffic infrastructure, increases a large amount of maintenance cost, has potential safety hazards, and even has major accidents of bridge collapse, so the traffic measurement weight limiting system is very important.
