Method, device and equipment for managing and controlling upstream vehicle of construction road section and medium

Abstract

The invention discloses a method, device and equipment for managing and controlling upstream vehicles of a construction road section and a medium, and the method comprises the steps: obtaining the predicted traffic capacity of a planned construction road section according to the predicted traffic speed and the predicted number of passable lanes; according to the predicted traffic flow and the predicted traffic capacity, obtaining a predicted accumulated queuing flow; according to the predicted cumulative queuing flow, the flow ratio, the vehicle body length and the interval length between the vehicles, the predicted cumulative queuing length is obtained; according to the predicted traffic capacity, the predicted cumulative queuing flow, the maximum allowable queuing length of the upstream of the planned construction road section, the predicted cumulative queuing length, the flow ratio, the vehicle body length and the interval length between the vehicles, the maximum total number of the upstream released vehicles is obtained through calculation; and according to the product of the upstream entrance control flow ratio and the upstream maximum release vehicle total number, obtaining the upstream control entrance maximum release vehicle number. The method provides a scientific basis for the traffic organization of the construction road section, and improves the traffic efficiency of the construction area.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a method, device, equipment and storage medium for managing and controlling upstream vehicles in a construction section. Background technique [0002] With 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 transportation infrastructure conditions 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 in the bottleneck section, and once the traffic congestion is generat...

Problems solved by technology

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 in the bottleneck section, and once the traffic congestion is generated, the traffic capacity will decrease.

[0003]At present, only warning road signs are set up in highway construction areas in our country, and the control methods are very unsound, which will easily lead to a serious decline in traffic capacity in construction areas, increased traffic delays and a series of traffic accidents.
