Video tracking type detection method and system capable of reducing stop frequency at intersection

Abstract

The invention provides a video tracking type detection method and system capable of reducing the stop frequency at an intersection. According to the video tracking type detection method and system capable of reducing the stop frequency at the intersection, each vehicle passing through the intersection is tracked continuously through a video tracking unit with the video tracking function, the speed and the position of each vehicle can be detected accurately, the time when each vehicle reaches a monitoring position of a next intersection under the condition that the vehicle runs at the current speed can be judged, and the problem that the current states of the vehicles can be detected only on the cross section of a position near a stop line at the intersection or a position certain distance away from the stop line at the intersection at present is solved. In addition, by the adoption of the video tracking type detection method and system capable of reducing the stop frequency at the intersection, it can be guaranteed that a green light turns on before a vehicle stream reaches the stop line at the intersection after the direction with the large flow is judged accurately judged. In this way, the frequency that the vehicles in the direction with the large traffic flow encounter red lights is reduced, and the stop time of the vehicles in the direction is shortened.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a video tracking detection method and system capable of reducing the number of parking at intersections. Background technique [0002] As the density of the urban road network continues to increase, the number of motor vehicles is increasing rapidly, and the number of intersections controlled by traffic lights at urban intersections is also increasing, especially in the city center. When these crossings often stop many times, the time of travel is constantly extended, which brings inconvenience to people's travel. by figure 1 The intersection shown is taken as an example, wherein intersection 1, intersection 2 and intersection 3 are all provided with signal lights. If the control of the signal lights at the three crossings cannot be coordinated, the vehicle will be stopped and waited when encountering a red light at crossing 1, crossing 2 and crossing 3.

Problems solved by technology

[0004] The present invention solves the problem in the prior art that when the current speed of a vehicle in a direction with a relatively large flow rate changes due to the influence of environmental conditions, the initial moment of the green light of the traffic signal machine at the downstream intersection cannot be changed according to the change of the speed of the vehicle, and it cannot be accurately positioned on the vehicle. When reaching the set position, a green light signal is given, thereby providing a video tracking detection method and system that can reduce the number of parking at intersections
