A timing method, device, computer equipment and storage medium for signal-controlled intersection green light interval time

Abstract

The invention relates to the technical field of intelligent transportation, and discloses a timing method, device, computer equipment and storage medium for signal-controlled intersection green light interval time. In each of the two adjacent traffic signal phases, the clearing traffic flow trajectory line corresponding to the preceding traffic signal phase and the incoming traffic flow trajectory line corresponding to the subsequent traffic signal phase are analyzed for the clearing traffic flow trajectory line and the incoming traffic flow trajectory. For the two entry lanes intersected by the track lines, the corresponding clearing time is calculated. Finally, all the calculated clearing times are summarized, and the clearing time with the largest value is selected as the green light interval corresponding to the two adjacent traffic signal phases. Therefore, it is suitable for automatic, precise and scientific green light interval timing for different types of intersections while avoiding the difficulty of collecting data and inaccurate data.

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 signalling the interval time of green lights at an intersection. Background technique [0002] Signalized Crossing is a scientific and technical term for highway traffic announced in my country in 1996, also referred to as an intersection, which refers to an area formed by at least two lines intersecting on the same plane. The traffic capacity directly affects the carrying capacity of the entire transportation network. Common intersections where two roads intersect have four directions, and when a road reaches the end at the intersection, it is called a three-way intersection / T-intersection, and some intersections have more than four directions, but due to The inefficiency of traffic operation, such intersections should be avoided as much as possible in the design. At signal-control...

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
