Timing method and device for green light interval time of signal control intersection, computer device and storage medium

Abstract

The invention relates to the technical field of intelligent traffic, and discloses a timing method and device for green light interval time of a signal control intersection, A computer device and a storage medium. The method comprises: according to lane basic data of signal control intersections and historical vehicle track data, generating an emptying traffic flow track line corresponding to a previous traffic signal phase and an entering traffic flow track line corresponding to a later traffic signal phase in two adjacent traffic signal phases of each entrance lane, and aiming at two entrance lanes of which the emptying traffic flow track line and the entering traffic flow track line are crossed, calculating to obtain corresponding time required for emptying, finally summarizing all the time required for emptying obtained by calculation, and selecting the time required for emptying with the maximum value as the green light interval time corresponding to the two adjacent traffic signal phases, thereby avoiding difficulty in data acquisition and data inaccuracy, and the method is suitable for carrying out automatic, accurate and scientific green light interval time timing on different types of intersections.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a timing method, device, computer equipment and storage medium for signal-controlled intersection green light interval time. Background technique [0002] Signalized Crossing (Signalized Crossing) is a scientific and technical term for road traffic published in my country in 1996, also referred to as crossing, which refers to the area formed by the intersection of at least two lines on the same plane. As the throat of road traffic, it has The traffic capacity directly affects the carrying capacity of the entire transportation network. A common intersection where two roads intersect has four directions, and when a road reaches the end at the intersection, it is called a three-way intersection / T-shaped intersection, and some intersections exceed four directions, but due to Due to the inefficiency of traffic operation, such intersections should be avoi...

Problems solved by technology

[0005] In order to solve the problems of poor applicability, difficult data collection and inaccurate data existing in the existing green light interval time matching method, the purpose of the present invention is to provide a new method for controlling the green light interval time at intersections based on high-precision vehicle trajectory data configuration signals , device, computer equipment and storage medium, according to the lane basic data and historical vehicle trajectory data of the signal control intersection, generate the cleared traffic flow trajectory lines corresponding to the previous traffic signal phases of each entrance lane in two adjacent traffic signal phases and the incoming traffic flow trajectory line corresponding to the subsequent traffic signal phase, and for the two entrance lanes where the cleared traffic flow trajectory line intersects with the incoming traffic flow trajectory line, the corresponding clearing time is calculated, and finally all the calculated clearing time For the required time, the time required for clearing with the largest value is selected as the green light interval time corresponding to the phases of the two adjacent traffic signals, so that it can be applied to different types of intersections while avoiding the difficulty of collecting data and inaccurate data. Automatic, accurate and scientific green light interval timing, which is convenient for practical application and promotion
