Embodiment 1

[0032] This embodiment provides a system that can dynamically monitor the efficiency of green lights at intersections, such as figure 1 As shown, it includes a video tracking module, a judging module, a display module, a first processing module, a second processing module and an analysis processing module. in:

[0033] The video tracking module continuously tracks each vehicle in each direction of the intersection, obtains the location information of each vehicle within the video tracking range in real time, and accurately records the positions of stop lines in different directions of the intersection.

[0034] The judging module receives the signal lamp control signal from the signal lamp controller, and judges whether the current moment is the starting point of the signal control period.

[0035] The display module, at the starting point of the signal control period, displays the saturation of each green light phase monitored in the previous signal control period.

Embodiment 2

[0047] This embodiment provides a method for dynamically monitoring the traffic efficiency of green lights at intersections, including the following steps:

[0048] S1: Use video tracking technology to continuously track each vehicle in all directions at the intersection, continuously track each vehicle in all directions at the intersection, obtain the location information of each vehicle within the video tracking range in real time, and accurately record the intersection The position of the stop line in different directions.

[0049] S2: Determine whether the current moment is the starting point of the signal control cycle, if so, go to step S3, otherwise go to step S4.

[0050] S3: Display the saturation of each green light phase monitored in the previous signal control cycle, and then return to step S1.

[0051] S4: Determine whether the first direction is a green light, and if so, record and add the time taken by the vehicle in the first direction to pass the stop line, w...

Abstract

The invention provides a system and method capable of dynamically monitoring the green light passing efficiency of an intersection. The control effect of traffic signals of the intersection can be monitored in each signal control cycle. By means of the video tracking technology, position information of vehicles is obtained in real time, the positions of stopping lines, in different directions, of the intersection are accurately recorded, and therefore the moment when the vehicle head of each vehicle makes contact with the corresponding stopping line and the moment when the vehicle tail of the vehicle leaves the stopping line are accurately obtained during the green light time, wherein the difference value between the two moments is the time spent when the vehicle passes through the stopping line, and in other words, the difference value is the real time spent when the vehicle occupies the stopping line; thus, the accurate saturation degree information can be obtained after the sum of the two moments divides the time of the green light phase, and the control effect of an intersection signal control system can be dynamically and accurately monitored in real time.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a system and method capable of dynamically monitoring the traffic efficiency of green lights at intersections. Background technique [0002] The intersection traffic signal control system is an important part of the traffic command and control platform. It is one of the effective means to standardize the traffic order at the intersection, prevent and reduce traffic accidents, and improve the efficiency of intersection traffic. How to dynamically evaluate the intersection signal control system in improving the efficiency of intersection traffic The control effect has always been a topic of concern. [0003] For the monitoring of traffic signal control effects at intersections, real-time monitoring should be carried out in each signal cycle: the key indicator that determines the green signal ratio and cycle of signal control is saturation, which refers to the sum...
