Abstract

The invention provides a vehicle queuing length detection system, method and device. The system comprises an entry detector, a stop line detector and a detection server, wherein the entry detector is embedded in an entry of a detected road section; the stop line detector is embedded in a stop line of the detected road section; the detection server respectively interacts with the entry detector and the stop line detector; the entry detector is used for detecting the amount of entering vehicles of the detected road section; the stop line detector is used for detecting the amount of leaving vehicles of the detected road section; the detection server is used for obtaining the amount of the entering vehicles and the amount of the leaving vehicles, and detecting the vehicle queuing length of the detected road section according to the amount of the entering vehicles and the amount of the leaving vehicles. Through the vehicle queuing length detection system, method and device provided by the embodiment of the invention, the vehicle queueing length detection accuracy of roads can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a vehicle queue length detection system, method and device. Background technique [0002] At present, the problem of traffic jam at the intersection of urban roads in our country is becoming more and more serious. As the number of vehicles continues to rise, urban roads are increasingly congested, resulting in frequent urban road traffic accidents. Once congestion occurs on the road, it will directly reduce the operating efficiency of the road network and easily induce secondary accidents. In order to improve the traffic capacity of road intersections and link traffic jams, it is necessary to calculate the vehicle queuing length of each road section. It provides a basis for further optimizing the configuration scheme of traffic lights. [0003] In related technologies, the queue length of vehicles at intersections is usually estimated by calculating formulas, using ind...
