Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 2 Shown is the schematic flow chart of the present invention, set up the high-definition camera at the upstream of the road section where overflow will occur, monitor and photograph the physical queuing behavior of vehicles in this road section, and judge whether the overflow occurs by image recognition technology; The flow method is: calibrate the maximum possible queuing length area of ​​the photographed road section, and delineate a virtual boundary in the image. Vehicles that exceed this boundary line up, and the vehicles run within a small speed range, which is considered to be overflow occur. If the overflow is judged by image recognition technology, it is necessary to use the discriminant model to identify the true and false overflow. If it is a false overflow, the upstream red light signal will not be turned on. If it is ...

Abstract

The invention discloses a traffic overflow control method based on a video feedback. A high definition camera is utilized to monitor a queuing condition of vehicles on a road; a true-false overflow distinguishing model is established for identifying the generation of true overflow; before the true overflow is generated, a red light signal on the upstream of the road is started; and the vehicles are prevented from continuing to enter into the road, so that the traffic jam caused by parking the vehicles at a road junction is avoided. The method comprises the following steps: 1) erecting the high definition camera at the road junction on the upstream of the road, through which the vehicles pass; 2) continuously shooting the queuing condition of vehicles on the road by the high definition camera; 3) identifying if overflow occurs according to an image recognition method, if yes, skipping to the step 4) for continually executing, and if not, skipping to the step 2) for continually shooting; 4) utilizing the distinguishing model to identify the truth of the overflow, if the overflow is true, skipping to the step 5), otherwise, skipping to the step 2) for continually shooting; and 5) starting the red light signal on the upstream and preventing the vehicles from entering into a downstream road, thereby preventing the generation of the overflow.

Description

technical field [0001] The invention relates to a method of traffic control technology, in particular to a traffic overflow control method based on video feedback information and image recognition technology. Background technique [0002] There are various manifestations of urban traffic congestion, among which road section overflow is one of them. Road section overflow refers to the formation of queues due to the bottleneck effect of the intersection, which causes the number of vehicles entering the road section to be greater than the number of vehicles leaving the road section. When the vehicle queue exceeds the length of the road section, overflow is formed. The harm of traffic overflow is huge. If it is not prevented and controlled, the entire city will cause large-scale traffic jams due to the mutual locking of vehicles at intersections, and the final result may paralyze the traffic of the entire city. [0003] At present, there are not many cities in my country that i...
