With the development of economy, there are more and more road vehicles, and highway traffic accidents are frequent. The demand for various aspects of wreckers is constantly being upgraded, but now the expressway has not formed a complete highway obstacle rescue system. It is impossible to establish a unified high speed rescue and rescue department. The highway wrecker is mainly used for road clearing work. The initial stage was mainly implemented by high-speed traffic police management. With the development of the society and the increasing demand for expressways, many high-speed vehicles contracted and established by private auto repair plants have emerged. The highway clearing organization helps to complete the road clearing work and deal with the special conditions of various highways. The highway obstacle rescue and rescue work is not only performed by high-speed traffic police management, but also involves the participation of private contractors. On the one hand, it can help solve the problem of the normal operation of high-speed vehicles. On the other hand, private participation has caused the failure of toll collection procedures for expressways. Reasonable, reflecting the double-sided effect of road rescue. The use of networked toll collection to achieve the fast, safe and efficient characteristics of highway obstacle clearing operations, and the establishment of a complete highway obstacle rescue and rescue department will be a complex and comprehensive system engineering.
