Problems solved by technology

And its data volume is increasing with the increase of the number of traffic control systems, the load of the central control system is getting higher and higher, and the stability is also reduced, and the central control system needs to be replaced to improve performance when necessary
Moreover, the disaster tolerance of the central control system is not good. Once the central control system is shut down, the traffic control system in the entire region will not be able to operate intelligently.

Embodiment 1

[0039] Such as figure 1 , figure 2 and image 3As shown, a distributed intelligent traffic control system, this intersection is a main road intersection, specifically an east-west road and a north-south road intersection, an independent control system is set at this intersection, including a control box 3, and 4 Two groups of vehicle identification devices 2 (the traffic lights 1 in front of the intersection stop line and the stop line rear) are all provided with in the two directions (i.e. eastward and westward of the east-west road, southward and northward of the north-south road) Only the first group of vehicle identification devices close to the stop line is displayed, the second group of vehicle identification devices is set in the direction of the first group of vehicle identification devices), and the control box is set next to the pole frame where one of the traffic lights at this intersection is located , the control box 3 is connected to the traffic light 1 and th...

Embodiment 2

[0053] A distributed intelligent traffic control system, the intersection is the intersection of the trunk road and the branch road, specifically the intersection of the east-west trunk road and the north-south branch road, wherein the north-south branch road is on the north side of the east-west trunk road It is a residential area, and there is a school on the south side of the east-west main road. The main road has a large traffic flow on a daily basis, but during weekdays, there is a large traffic flow on the branch road during morning and evening get off work and school.

[0054] Set up an independent control system at this intersection, including a control box. The four directions of this intersection (that is, the eastward and westward directions of east-west roads, and the southward and northward directions of north-south roads) are all set in front of the stop line at the intersection. A group of vehicle identification devices 2 behind the traffic lights 1 and the stop l...

Abstract

The invention discloses a distributed intelligent traffic control system, which belongs to the technical field of traffic control, and is characterized in that an independent control system is arranged at each intersection and comprises a control box, traffic lights in front of a stop line of the intersection and one or two groups of vehicle recognition devices behind the stop line, the control box is connected with traffic lights in front of the stop line of the intersection and the one or two groups of vehicle recognition devices behind the stop line, and the control box is connected with control boxes of all intersections adjacent to the intersection. The independent traffic control system is arranged at the intersection for carrying out statistics and prediction on traffic flows in all directions of the intersection; and the traffic control system of the intersection is connected with the traffic control systems of the adjacent intersections, acquires vehicle prediction data of other intersections towards the direction of the intersection, then performs optimization processing and conducts processing actions.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a distributed intelligent traffic control system. Background technique [0002] The traditional traffic control system is to set up traffic lights at intersections, and the turn-on time of traffic lights is fixed. In the early society, when the number of vehicles was small and the traffic flow on the road was very small, this control method effectively controlled the traffic conditions at intersections. [0003] With the increase of social vehicles, the number of vehicles on the road in the city has increased significantly, especially the traffic flow on the main road in the city has increased significantly. At this time, the traditional traffic control system at the intersection of the main road will cause a backlog of vehicles on the main road in the city. In order to solve the problem of rapid passage on the main road, the urban traffic management department gathers th...
