Alternating passage control method for interwoven road sections

Abstract

The invention discloses an alternate traffic control method for an interlaced road section, and relates to the technical field of intelligent traffic control, and the method comprises the steps: obtaining the lane traffic state information of two lanes through the refined organization of the interlaced road section and the presetting of signs, marked lines and signal lamps; determining a switching period of the signal lamp; in each switching period, when waiting vehicles exist on the two lanes, the sum of the waiting time of all the vehicles on the two lanes is calculated according to the traffic state information of the lanes and the waiting time cost function of the lanes; the total waiting time of all vehicles on the lane can reflect the total delay time of the lane; and controlling the phases of the two signal lamps according to the total delay time of the two lanes. According to the invention, the requirement that traffic flows from different directions go to different destinations can be met, vehicles can safely and quickly pass through the interlaced road section, the congestion bottleneck of the interlaced road section is eliminated, and the occurrence rate of traffic accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a traffic control method for interweaving road sections. Background technique [0002] Weaving road sections form congestion trigger points due to their short meeting distance, many traffic conflicts, and high accident risks, which often lead to road congestion or even paralysis in an area during peak hours. Vehicles passing through the interweaving road section need to cross one or more lanes to enter the destination lane within a limited distance of the interweaving road section in order to select a destination. Due to the short distance of merging and diverging, conflicts are likely to occur during the merging and diverging process, making the traffic flow highly chaotic. , leading to a significant reduction in the traffic capacity of the interweaving road section and a sharp increase in driving risk. [0003] Currently, there are two mainstream control me...

Problems solved by technology

[0010] In view of this, the present invention proposes an alternate traffic control method for interweaving road sections, which solves the problems existing in existing interweaving road sections due to the unfixed position and direction of motor vehicles changing lanes, and the mismatch between traffic signal light control methods and actual traffic conditions. Low traffic efficiency and low road use efficiency to meet the needs of traffic travelers and improve travel efficiency and safety in intersecting road sections
