Abstract

The invention provides a vehicle queuing length simulation system, method and device. An entrance detector and a stop line detector are respectively arranged at an entrance and a stop line of a detection road section, and a simulation server interacting with the entrance detector and the stop line detector is arranged, enabling the simulation server to simulate a vehicle traveling track in the detection road section by acquiring driving-in vehicle information detected by the entrance detector and driving-away vehicle information detected by the stop line detector according to a collected signal change period of traffic lights, and determine a vehicle queuing length according to the vehicle traveling track; the simulation server carries out dynamic calculation based on acquired traffic road condition data, so that the accuracy of the vehicle queuing length is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of data processing, and in particular to a vehicle queue length simulation system, method and device. Background technique [0002] At present, the problem of traffic congestion at intersections of urban roads in my country is becoming more and more serious. As the number of vehicles continues to rise, urban roads are becoming increasingly congested, leading to 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. Therefore, in order to reduce the negative impact of traffic accidents, it is necessary to calculate the length of the vehicle queue for each road section. [0003] In related technologies, the queuing length of vehicles at the intersection is usually calculated by using calculation formulas, using indicators such as road saturation, vehicle release time, flow, and using mathe...
