Method for detecting dynamic queue length of vehicles

Abstract

The invention discloses a method for detecting the dynamic queue length of vehicles. The method comprises the following processes traveling tracks of the vehicles in a detection area are tracked, thepositions and speed of the vehicles are obtained, and zoning management is conducted by using a lane as a unit; the speed of the vehicles and the distance between the two adjacent vehicles in the samelane are compared with a set dynamic queue speed threshold and dynamic queue distance threshold, and whether the vehicles belong to a dynamic queue or not is determined; and the dynamic queue lengthis calculated according to dynamic queues of lanes. According to the method for detecting the dynamic queue length of the vehicles, track tracking detection is conducted on the vehicles in the lanes,the length of the queuing vehicles in the lanes are dynamically calculated, so that the data result is more actual and accurate, and an accurate basis is provided for traffic intelligent management; and the method can further calculate the queuing length of the lanes, and the queuing length is output according to the lanes.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic management, and in particular relates to a vehicle dynamic queuing length detection method. Background technique [0002] Traffic control is a social public welfare undertaking related to the national economy and the people's livelihood. It is closely related to the production and life of the public. The stable and sustainable development of cities and the improvement of people's living standards play an important role. Due to the control of traffic lights, the queuing behavior of vehicles in the urban traffic network under high saturation will inevitably occur, and the accurate acquisition of the dynamic queuing length of vehicles is necessary for traffic congestion assessment, intersection signal light control timing, and traffic flow overflow control. An important prerequisite for intelligent management. [0003] In the prior art, the calculation of the dynamic queuing length of v...
