Embodiment 1

[0061] figure 1 A flow chart of the traffic light control method provided in Embodiment 1 of the present invention. The embodiments of the present invention provide a traffic light control method for the problems that the control of traffic lights in the prior art is not flexible enough, and once traffic congestion occurs, the traffic police need to go to the congested intersection to perform on-site control, which consumes a lot of manpower and does not deal with the congestion in time. .

[0062] The method in this embodiment is applied to a distributed traffic light intelligent cooperation system. The system includes: a plurality of traffic lights arranged at intersections, and each traffic light is correspondingly provided with a signal controller, a traffic light gateway and an image acquisition device. The execution body of the embodiment of the present invention is a traffic light gateway.

[0063] Among them, the signal controller corresponds to the traffic light one...

Embodiment 2

[0094] figure 2 A flow chart of the traffic light control method provided by the second embodiment of the present invention. On the basis of the above-mentioned first embodiment, in this embodiment, the traffic light gateway determines whether the controlled road is congested according to the traffic road condition image and the preset neural network model. like figure 2 As shown, the above step S101 can be implemented by the following steps:

[0095] Step S201, the traffic light gateway preprocesses the traffic road condition image.

[0096] In this embodiment, the traffic light gateway may be any traffic light gateway in the intersection.

[0097] The traffic light gateway preprocesses the traffic image, which can be implemented in the following ways:

[0098] The traffic light gateway performs clipping processing on the traffic road condition image to obtain an image of a preset size; the traffic light gateway performs normalization processing on the image of the preset...

Embodiment 3

[0117] image 3 A flow chart of the traffic light control method provided in Embodiment 3 of the present invention. On the basis of the second embodiment above, in this embodiment, after the traffic light gateway sends the control application to other traffic light gateways at the intersection, if it is within a preset time period before sending the control application, or a preset time after Within the segment, upon receipt of the regulation application sent by other traffic light gateways, the adjudication gateway sends traffic light control right adjudication information to the adjudication gateway, and the adjudication gateway determines the priority level of each traffic light gateway for obtaining traffic light control rights. like figure 2 As shown, after the above step S102 and before the step S104, the following steps are further included:

[0118] Step S105: If a control application sent by other traffic light gateways is received within a preset time period befor...

Abstract

Embodiments of the present invention provide a traffic light control method, a device, a traffic light gateway, and a storage medium. According to the method of the embodiment of the present invention, according to the traffic light gateway in the intersection, it is determined whether the controlled road is congested according to the traffic road condition images captured in real time; if it is determined that the controlled road is congested, the control is sent to other traffic light gateways at the intersection. If the traffic light gateway does not receive the control application sent by other traffic light gateways in the preset time period before and after sending the control application, then the roads controlled by other traffic light gateways in the intersection are not congested, and the intersection The only traffic light gateway whose controlled road is congested obtains the control right of the traffic light at the intersection, and controls the traffic light at the intersection according to the traffic image and signal light rules, so as to realize automatic and rapid response to traffic congestion and timely response to traffic congestion. Alleviate traffic congestion, improve the efficiency of congestion resolution, and reduce the workload of traffic police.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent traffic, and in particular, to a traffic light control method, a device, a traffic light gateway, and a storage medium. Background technique [0002] In recent years, with the sustained and rapid economic development, the number of motor vehicles in each city has grown rapidly. However, the speed of urban road construction is far from keeping up with the growth of motor vehicles, the urban traffic pressure has increased sharply, and traffic congestion often occurs in some areas, which has brought great challenges to the smooth operation of urban traffic. [0003] At present, the control durations of traffic lights at different intersections in urban roads are set in a balanced manner, and the control of traffic lights is not flexible enough, which is the main reason for urban road congestion. For example, the green light time of a congested road is too short, the green l...
