Embodiment Construction
[0039] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0040] The vehicle-road coordinated traffic light of the present invention can be applied to road intersections to guide vehicles through the intersection. The vehicle-road coordinated traffic light has the function of periodic change and the function of dynamically setting the duration of traffic lights. Among them, the periodic change function of the vehicle-road coordination traffic light means that the duration of the traffic li...

The invention discloses a vehicle-road coordinated traffic light and a control method for the vehicle-road coordinated traffic light. Vehicle-road collaborative traffic lights include: communication module, central processing module, GPS positioning module and dispatching module; communication module, used to receive message sets periodically sent by vehicles, and send message sets to the central processing module; GPS positioning module, used to Locate the position of the vehicle-road coordination traffic light, and send the position of the vehicle-road coordination traffic light to the central processing module; the central processing module is used to calculate and analyze the received message set and the position of the vehicle-road coordination traffic light, Dynamically set the duration of the traffic light of the vehicle-road coordinated traffic light, and send a control signal carrying the setting time to the scheduling module; the scheduling module is used to control the duration of the traffic light of the vehicle-road coordinated traffic light according to the control signal carrying the setting time, The real-time analysis of the traffic flow at the intersection is realized, and the duration of traffic lights is dynamically adjusted in real time to improve traffic efficiency.
Description
technical field [0001] The invention relates to the technical field of traffic lights, in particular to a vehicle-road coordinated traffic light and a control method for the vehicle-road coordinated traffic light. Background technique [0002] Traffic lights play an important role in traffic flow in cities. The current time change cycle of traffic lights is basically set, and is generally designed based on the principle of equal opportunities in crossing directions; Under certain circumstances, considering the large traffic flow on the main road, the traffic light passing time will be biased towards the principle that the main road is slightly longer. The above methods are all based on the method of equal opportunity or probability to control the time of traffic flow, and cannot be combined with real-time road conditions. [0003] At present, there is also a camera-based visual recognition of traffic flow and pedestrian flow at intersections, and then the design of adjustin...
