Problems solved by technology

[0004] But at every intersection, it is difficult to have traffic police on-site command 24 hours a day
There are also many problems and difficulties in dispatching traffic based on video. In particular, there are thousands of cameras in every city. Even if the monitoring video of intersections is transmitted to the control center, there are not so many dispatchers who monitor the video images at any time and make decisions based on the video. Adjust the control signals of each intersection in real time according to the vehicle situation on the road
Moreover, it is impossible for many traf

Embodiment 1

[0040] In the urban traffic control system of the present embodiment, an intersection in urban roads is taken as an example, such as figure 1 As shown, it includes four groups of traffic lights 1, several vehicle recognition cameras 2 and a local traffic controller 3, and the local traffic controller 3 is connected to the urban traffic control center through the mobile phone wireless network 4 for data information transmission.

[0041] Vehicle recognition camera 2, at least one set for each traffic direction, installed in the direction facing the vehicle entering the intersection, processing the image on the road, identifying and counting the vehicle type, quantity, driving speed and speed of each lane on the road according to vehicle characteristics The current location and pedestrian information on the sidewalk, and then the statistical data is connected to the local traffic controller 3 through the network cable according to the standard IEEE802.3 protocol; the vehicle reco...

Embodiment 2

[0044] Such as figure 2 , image 3 As shown, the urban traffic control system of the present embodiment is applied to urban roads at four crossings, a schematic diagram of a scheme for realizing centralized control through the mobile phone wireless network and the urban traffic control center, and each crossing is configured with a local controller 5 and several Vehicle recognition cameras, the vehicle recognition cameras at each intersection respectively collect the number of vehicles and pedestrians on the lanes in each direction on the corresponding intersection, the current position and the driving speed. The local controller 5 includes a standard network interface, and transmits the traffic statistics real-time data of each crossing collected by the vehicle recognition camera to the traffic optimization processing module; after the traffic optimization processing module packs the traffic statistics real-time data according to the communication protocol of the urban traff...

Abstract

The invention belongs to the technical field of intelligent traffic, and particularly relates to an urban traffic control system. The urban traffic control system comprises traffic lights arranged on intersections, local traffic controllers and a plurality of cameras, and the local traffic controllers and the cameras are arranged on the intersections. The traffic lights and the local traffic controllers are connected for signal control, the cameras transmit collected real-time traffic data information to the local traffic controllers, and the local traffic controllers on the intersections are connected with an urban traffic control center for data transmission. According to the urban traffic control system, the system is connected and matched with a vehicle recognition camera through data transmission, the real-time traffic state data information of all the intersections is collected in real time, after control over the traffic of the intersections is optimized, the traffic signals of all the intersections are centralizedly and coordinately controlled in real time, and optimal configuration of urban traffic is achieved. The invention further discloses an urban traffic control method. Intelligent and user-friendly urban traffic management is achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an urban traffic control system and a control method. Background technique [0002] The traffic light time of existing traffic control system is basically set by experience. The traffic control signal at the current intersection will not be adjusted in real time according to the change of traffic flow. There are often red lights in the direction with cars, and green lights in the direction without cars for a long time; When the red and green lights change, the car in the direction of the original green light is blocked at the intersection, and now the car in the direction of the green light cannot pass through the intersection, thereby further causing congestion at the intersection. The fact that the actual road vehicle status and traffic control signals are not synchronized will increase the number and time of vehicle stops, waste existing road re...
