Background
In recent years, along with the rapid development of national economy in China, the mileage of the highway is rapidly increased, and the traffic volume of the highway is in a situation of increasing continuously. However, the rapid increase of traffic and the increase of heavy-duty vehicles cause the road surface conditions and traffic facilities of some expressways to be damaged to different degrees, so that the phenomenon of constructing expressways is also frequently seen. When the highway is constructed, the traffic of the highway construction area needs to be organized so as to ensure the normal passing of vehicles.
In the related art, it is a common practice for traffic organization in a highway construction area to allow all vehicles to freely run in an interlaced manner. When the lanes in one direction of the highway are completely closed due to construction, vehicles in the direction have to run through the opposite lanes due to the characteristic of full-line closure of the highway, and all vehicles in two directions run in a freely-interwoven mode.
In view of the above-mentioned related technologies, the inventor thinks that the lane to be borrowed is shared by traffic flows of a plurality of lanes, so on one hand, traffic jam is caused, which results in low traffic efficiency, and on the other hand, because vehicles in two directions run in an interlaced manner, there is a huge potential traffic safety hazard.
