example 1
[0034] In this example, as figure 2 As shown, the above step 101 includes:
[0035] Step 201, analyzing the video of the traffic intersection, extracting multiple reference GPS trajectory data of multiple vehicles passing the traffic intersection with green lights within the preset first target time period for each flow direction, and multiple vehicle reference data within the preset second target time period. Multiple sample GPS trajectory data of a green light passing through a traffic intersection.
[0036] Specifically, obtain the video of the traffic intersection to be analyzed, analyze the video of the traffic intersection, and extract multiple reference GPS trajectory data of multiple vehicles passing the traffic intersection with green lights in each flow direction within the preset first target time period, wherein the second A target time period may be understood as a low-peak traffic period, such as 0:00-6:00 in the morning. The second target time period can be u...
example 2
[0047] In this example, calculate the standard passing speed of each vehicle at the corresponding traffic intersection, which can be pre-set according to the model of each vehicle, etc., and then obtain the actual vehicle speed reported by each vehicle that actually passes through the corresponding traffic intersection , calculate the speed difference between the actual vehicle speed and the standard passing speed, and input the pre-trained neural network model to obtain the vehicle passing delay time according to the mean value of the speed difference of all vehicles, wherein, the training method of the pre-trained neural network model can be obtained by prior art implementation, and will not be repeated here.
[0048] Step 102, according to the vehicle delay time of each flow direction and the corresponding preset cycle of the signal control equipment, the parking rate of each flow direction is obtained.
[0049] Specifically, since the delay time of vehicles in each flow di...
