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 in 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 at the moment, all vehicles in the two directions run in a freely-interwoven way.
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.

An auxiliary block 370 is rotated on the bracket, a rubber limiting block 371 is bonded on the auxiliary block 370, and the limiting block 371 can be clamped in the limiting groove 362, so that the baffle plate 360 is limited.
Referring to fig. 1 and 6, in the step S6, the traffic lights 420 at the intersection where a approaches the closed section to the road 100 are set as the first group, and the traffic lights 420 at the intersection where B approaches the closed section to the road 200 are set as the second group. The two groups of traffic signal lamps 420 each include a first traffic light 421, a second traffic light 422, and a third traffic light 423, the first traffic light 421 of the first group corresponds to a lane closest to the road 200 from the road 100 to the road B, the second traffic light 422 of the first group corresponds to a lane farthest from the road 100 to the road 200 from the road 100 to the road B, and the third traffic light 423 of the first group corresponds to a middle lane of the road 100 to the road a. The first traffic light 421 of the second group corresponds to a lane farthest from the B-direction road 200 toward the a-direction road 100, the second traffic light 422 of the second group corresponds to a lane closest to the B-direction road 200 toward the a-direction road 100, and the third traffic light 423 of the second group corresponds to a middle lane of the B-direction road 200.

The lighting color of the traffic lights in each group of traffic lights 420 changes intermittently in a red-green shape. When the vehicle on the road 100A changes to the road 200B, the distance from the vehicle on the lane 100A to the lane B to the vehicle on the lane closest to and farthest from the lane 200A, and the vehicle on the lane in the middle of the lane 100A stays firstly; when the vehicle on the B-direction road 200 passes through the closed road section, the vehicle on the lane closest to and farthest from the a-direction road 100 passes through the B-direction road 200 first, and the vehicle on the middle lane of the B-direction road 200 stops first.

Referring to fig. 7, the first camera 424 and the second camera 425 are both electrically connected to the traffic signal control system, after the first camera 424 and the second camera 425 capture a vehicle, the image signal is transmitted to the traffic signal control system, and after comparison of the traffic signal control system, the traffic signal control system sends a control signal to the first group of variable lamps 383 and the second group of variable lamps 383. If more vehicles are captured by the first camera 424 than by the second camera 425, the traffic signal control system controls the first group of variable lights 383 to be green lights and the second group of variable lights 383 to be red lights, so that the vehicle in the a-direction road 100 can only borrow the lane B to the road 200 to be the lane closest to the a-direction road 100.
The implementation principle of the traffic signal control method for the passage by lane in the closed construction area of the expressway in the embodiment of the application is as follows: after determining that the A-direction road 100 is a closed road section, a constructor moves the two adjusting supports 300 and the two passing supports 400 to two road opening designated positions of the closed road section;
then, the electric push rods 340 corresponding to the adjusting bracket 300 and the passing bracket 400 are respectively started, so that the roller 331 is contracted into the accommodating groove 321, and the mounting table 320 is directly abutted to the ground;
then the traffic signal control system controls a first traffic light 421 and a second traffic light 422 in each group to synchronously light up green lights, a third traffic light 423 lights up red lights, and the traffic signal control system controls a first normally-on light 381 of the first group to be normally green, a second normally-on light 382 of the first group to be normally red, a first normally-on light 381 of the second group to be normally red, and a second normally-on light 382 of the second group to be normally green, so that vehicles on the A-direction road 100 are intermittently changed to the B-direction road 200, and vehicles originally driving on the B-direction road 200 intermittently pass through a closed road section when passing through the closed road section;
after the first camera 424 and the second camera 425 capture the vehicles, the image signals are transmitted into a traffic signal control system, and after comparison of the traffic signal control system, if the vehicles captured by the first camera 424 are more than the vehicles captured by the second camera 425, the traffic signal control system controls the first group of variable lamps 383 to be green lamps and the second group of variable lamps 383 to be red lamps, so that the vehicles in the road A to the road 100 can only borrow the lane B to the road 200 and the lane A to the road 100 closest to the road 100; if the first camera 424 captures less vehicles than the second camera 425 captures, the traffic signal control system controls the first group of variable lights 383 to be red lights and the second group of variable lights 383 to be green lights, so that the vehicles in the A-direction road 100 can borrow the B-direction road 200 to be the middle lane and the B-direction road 200 to be the closest lane to the A-direction road 100.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
