Embodiment 1

[0039] A traffic light control method for a smart city, as attached figure 1 shown, including the following steps:

[0040] Real-time acquisition of road section images of the road where the traffic lights direct the vehicle.

[0041] Determine whether there are parked vehicles on the road according to the road section image.

[0042] If there is a parked vehicle on the road, the lane where the parked vehicle is located and the adjacent lane are identified according to the road section image.

[0043] According to the image of the road section, the lane where the vehicle is located, and the adjacent lanes, it is judged whether there is a traffic jam in the lane where the parked vehicle is located.

[0044] If there is a traffic jam in the lane where the vehicle is parked, a signal light control instruction is generated.

[0045]Adjust the timing scheme of the traffic signal light according to the control instruction of the signal light, and control the turn-on time of the g...

Embodiment 2

[0062] The differences between this embodiment and Embodiment 1 are:

[0063] The method for controlling traffic lights in a smart city further includes the following steps:

[0064] Obtain road images of the road section between two traffic lights in real time.

[0065] Generate vehicle parking rates for road segments between two traffic lights from road images.

[0066] Generate signal light regulation instructions according to the vehicle parking rate and the preset parking rate range.

[0067] Specifically, obtaining the road image of the road section between two traffic lights in real time includes the following steps:

[0068] Cooperate with a third-party platform to obtain real-time access to the road between the two traffic lights through the driving recorder of the vehicles parked on both sides of the road, the driving recorder of the vehicle driving in the section between the two traffic lights, and the cameras at the door of the shops on both sides of the road im...

Embodiment 3

[0079] The difference between the present embodiment and the second embodiment is that if the parked vehicles are still parked on the lane for a long time after the single-lane congestion is caused, the traffic congestion of the entire road is likely to be caused.

[0080] In this embodiment, the traffic signal light control method for smart city also includes the following steps:

[0081] Pre-store appeasement information, negotiation point coordinates and information templates of multiple blank locations. For example, the appeasement information indicates that the current accident is a rubbing accident. If both parties are equally responsible, the maximum compensation for each party is X yuan. If one party is responsible, the maximum compensation is Y yuan. At the same time, the incident has been videotaped and the relevant evidence has been preserved. Please rest assured that the values ​​of X and Y are determined by the current accident compensation standard. For example, t...

Abstract

The invention relates to the technical field of traffic guidance, in particular to a traffic signal lamp control method and system for a smart city. The method comprises the following steps: obtaininga road segment image of a road where a vehicle commanded by a traffic signal lamp is located in real time; the method is characterized by including the steps of judging whether vehicles are parked ona road according to road section images; if the parked vehicle exists on the road, identifying a lane where the parked vehicle is located and an adjacent lane according to the road section images; according to the road section images, the lane where the vehicle is located and the adjacent lane, judging whether traffic jam occurs in the lane where the parked vehicle is located; if the lane where the parked vehicle is located is subjected to traffic jam, generating a signal lamp regulation and control instruction; and adjusting the timing scheme of a traffic signal lamp according to the signallamp regulation and control instruction, and controlling the turn-on duration of the green light of the traffic signal lamp according to the adjusted timing scheme. By adopting the scheme, the technical problem that the traffic jam condition of each lane cannot be effectively monitored in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of traffic guidance, in particular to a traffic signal light control method and system for smart cities. Background technique [0002] Traffic signal lights are signal lights for directing traffic operations. They are generally composed of red lights, yellow lights and green lights. Red lights represent prohibition of passage, yellow lights represent warnings, and green lights represent permission to pass. The most common traffic lights in cities are crosswalk signal lights and lane signal lights, wherein crosswalk signal lights are used to direct pedestrians to pass on crosswalks, and lane signal lights are used to direct vehicles to pass on lanes. [0003] With the rapid growth of car ownership in my country's cities, traffic congestion is becoming more and more serious, and there are various reasons for traffic congestion. For example, the supply of original road facilities is relatively insufficient, so ...
