Background technique

With the continuous acceleration of road construction in our country and the rapid growth of the number of motor vehicles, the use of expressways is increasing. When a large number of motor vehicles are driving fast on the expressway, traffic accidents, illegal parking, reverse driving, etc. occur from time to time. When traffic accidents occur, some drivers will place warning triangles behind the vehicles in time. On the expressway, the warning triangle should be placed 150 meters behind the vehicle. Therefore, in order to reduce the distance, some drivers do not place the warning triangle at all, and even do not put the warning triangle. The possibility is low; for vehicles traveling in the reverse direction, it is impossible to place a warning triangle. In the event of a traffic accident, illegal parking, reverse driving, etc., if the vehicles coming from behind cannot receive the early warning in time, it is very likely to cause a secondary traffic accident.
