Embodiment approach

[0061] As an implementation manner, the vehicles to be released include stationary waiting vehicles and mobile vehicles.

[0062] Among them, the stationary waiting vehicle is the vehicle on the current road waiting for release at the intersection; the mobile vehicle is the vehicle in the current state of driving on the road and has not yet driven to the waiting position for release.

[0063] Then, when counting the number of vehicles to be released, not only the number of stationary waiting vehicles in the image needs to be counted, but also the number of mobile vehicles in the image needs to be counted. The number of stationary waiting vehicles and the number of mobile vehicles are summed, and the obtained number is the number of vehicles to be released.

[0064] Step S30 , according to the number of the vehicles to be released, calculate the time required for the vehicles to be released to pass through the intersection.

[0065] After obtaining the number of vehicles to be...

Abstract

The invention discloses a traffic light control method. The method comprises the following steps of if traffic light corresponding to a road is in a no passing state, and when remaining time of the nopassing state is reduced to preset time, collecting images of vehicles on the road, wherein the road is intersected with other roads at an intersection; according to the images, calculating a numberof the vehicles to be released on the road; according to the number of the vehicles to be released, calculating release time needed by the vehicles to be released passing the intersection; and when the remaining time of the no passing state is reduced to zero, switching the traffic light corresponding to the road to be in a release state, and according to the release time, maintaining the releasestate, and correspondingly controlling traffic light states corresponding to the other roads. The invention also discloses a traffic light control apparatus. In the invention, regulation and control of the traffic light are flexible and are not limited by a fixed regulation and control period, and pavement resources are effectively released so that traffic at the intersection is smooth.

Description

technical field [0001] The invention relates to the technical field of traffic lights, in particular to a traffic light control method and device. Background technique [0002] At present, the traffic lights we use usually control the switching of red, green and yellow signal lights according to a preset fixed cycle. [0003] However, because traffic conditions change in real time, due to reasons such as time and road direction, the traffic volumes on the roads intersecting at intersections are different. For example, there is a lot of traffic on the north-south road, and it takes multiple green lights to pass through. However, there are very few vehicles on the east-west road, and all the vehicles can be released within the green time. Switching signal lights at a fixed time will cause more congestion on the north-south road, and the green light time in the east-west direction will be wasted. [0004] It can be seen that the current traffic light control method is too rig...
