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...
