Intersection green light passing rate calculation method, device and equipment and storage medium

Abstract

The invention discloses an intersection green light passing rate calculation method, apparatus and device, and a storage medium. The method comprises the steps of obtaining basic safety information of a vehicle, map information of an intersection, a signal state of a traffic signal lamp and countdown information; carrying out the edge calculation according to the basic safety information, the map information, the signal state and the countdown information, and obtaining the green light passing rate of the divided lanes; and calculating the overall green light passing rate of the intersection according to the green light passing rates of the divided lanes. The method can improve the calculation precision of the green light passing rate, does not depend on the detection result of a fixed sensor, reduces the layout cost and maintenance cost, avoids the situation that the fixed sensor is damaged to cause the calculation error of the green light passing rate at the intersection to affect daily transportation, and can serve as an important index for traffic signal control optimization; the vehicle waiting time is reduced, the overall passing efficiency of vehicles at the intersection is improved, and the traffic pressure of a city is improved.

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 calculating the passing rate of a green light at an intersection. Background technique [0002] As an important index to evaluate the overall traffic efficiency of intersections and the optimization effect of traffic signal control, the green light passing rate has played an increasingly important role in the field of smart transportation. [0003] At present, a large number of scholars have conducted in-depth research on how to use the highest passing rate of green lights as the optimization goal of adaptive control of intersections. coil, etc.) to detect whether the vehicle arrives within the time range of the green light; however, this method of obtaining vehicle data through fixed sensors has some defects, such as the high cost of laying out the fixed sensor and high maintenance costs, such as the m...
