Embodiment Construction
[0065] The present invention will be further described below in conjunction with the accompanying drawings.
[0066] Such as figure 2 and image 3 As shown, a control method to improve the traffic efficiency of expressway construction area includes the following steps:
[0067] Step 1: Set up the traffic flow detector, the construction area warning column 4 and the roadside variable information sign 1. The specific setting method is as follows:
[0068] Set up a group of construction area warning columns 4 at the beginning of the construction area 5;
[0069] Set up a group of 1# traffic flow detectors 3-1 at the warning post 4 in the construction area;
[0070] Set up two groups of traffic flow detectors in the upstream of construction area 5, and the downstream group of traffic flow detectors is 2# traffic flow detector 3-2, and the distance between 2# traffic flow detector 3-2 and construction area 5 is 600 -800 meters, a group of traffic flow detectors in the upstream...

The invention discloses a control method for improving traffic efficiency of a freeway construction area. The control method includes the steps that on the basis that traffic flow operating data of freeway bottleneck road segments and the upstream of the freeway bottleneck road segments are acquired in real time, variable speed limiting values of the upstream of the bottleneck road segments are calculated, artificial control areas are formed on the upstream of the bottleneck road segments, traffic flow entering the bottleneck road segments is reduced when the queue-up phenomenon occurs on the bottleneck road segments, and therefore the phenomenon that traffic capacity of the bottleneck road segments is instantly reduced is avoided. Through the coordination control method, the traffic jam queue-up phenomenon of the bottleneck road segments beside the freeway construction area is relieved, and driving safety of vehicles on the bottleneck road segments is improved through deceleration in advance.
Description
technical field [0001] The invention belongs to the technical field of dynamic traffic control and intelligent traffic, in particular to a control method for improving traffic efficiency in expressway construction areas. Background technique [0002] With the deepening of reform and the continuous deepening of urbanization and motorization, my country's transportation industry has developed rapidly, the road network structure has been continuously improved, and the conditions of transportation infrastructure have been continuously improved. However, due to subjective and objective problems, some sections of the expressway need to be repaired due to damage. Therefore, some sections of the expressway are operating while being constructed. At this time, the side of the construction area becomes a bottleneck section of the expressway section. When the incoming traffic volume is large, there will be traffic congestion on the bottleneck road section, and once the traffic congestio...
