Problems solved by technology

In addition, traffic conditions at traffic intersections are ever-changing. When a certain direction is congested or multiple directions are congested, when the traffic lights are still controlled according to the predetermined method, not only does not alleviate the traffic congestion, but often aggravates the congestion.

Embodiment 1

[0055] figure 1 It is a schematic diagram of the composition and structure of an Internet of Vehicles platform according to an embodiment of the present invention. The Internet of Vehicles platform 10 includes: a data collection module 101, a congestion analysis module 102, and a switching decision module 103; wherein,

[0056] The data collection module 101 is used to obtain the driving data of vehicles within a set range on each road currently connected to the target traffic intersection;

[0057] The congestion analysis module 102 is used to calculate the traffic congestion index of each road according to the driving data and traffic congestion index calculation rules of vehicles within the set range on each road;

[0058] The switch decision module 103 is configured to determine that the traffic lights at the target intersection need to be adjusted based on the congestion control relationship table and the traffic congestion index of each road, and in the next traffic ligh...

Embodiment 2

[0134] Embodiment 1 of the present invention will be further described below through a specific example, Figure 4 It is a schematic flow chart of the specific realization of the traffic signal light control method in Embodiment 2 of the present invention, and the method is applied to scenarios such as Figure 5 For the T-shaped intersection shown, the roads connected to the T-shaped intersection are: roads from south to north, roads from north to south, and roads from west to east, and each road has 2 or 2 The above lanes can include at least one straight-through lane, or at least one left-turn lane, or at least one right-turn lane; the traffic lights at this T-shaped intersection include the first group of traffic lights 1 for controlling the road from south to north, and the first group of traffic lights 1 for controlling the road from north to north. The second group of traffic lights 2 on the south road, the third group of traffic lights 3 controlling the road from west t...

Abstract

The invention discloses a traffic signal lamp control method, comprising: acquiring the running data of vehicles within a set range on each road currently connected to a target traffic intersection; And traffic congestion index calculation rules, calculate the traffic congestion index of each road; When determining the traffic lights of the target traffic intersection based on the congestion control relationship table and the traffic congestion index of each road, in the next traffic light conversion cycle Within, the green light duration corresponding to the road with the largest traffic congestion index is increased by the time threshold, and the green light duration corresponding to the road with the smallest congestion index that is mutually exclusive with the road traffic direction with the largest traffic congestion index is reduced by time threshold. At the same time, the invention also discloses a vehicle networking platform.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a traffic signal lamp control method and a vehicle networking platform. Background technique [0002] With the continuous advancement of the urbanization process, the number of motor vehicles has increased rapidly, and the limited urban transportation resources cannot meet the increasing demand for vehicles, which makes the urban transportation system face greater pressure. However, improving or re-establishing urban traffic planning, such as building new roads and bridges, requires relatively large capital and long-term investment, and the amount of engineering is large, which is a long-term improvement process. Therefore, in order to ensure the normal operation of vehicles between urban roads and relieve urban traffic pressure, the control of traffic lights at traffic intersections is particularly important. [0003] However, most existing urban traffic control methods are relat...
