[0005] A T-shaped connecting frame is welded on the column surface of the signal lamp post, and infrared sensors are installed on both sides of the T-shaped connecting frame. A monitoring camera is installed on the cross bar end of the signal lamp post through a fixed frame. The traffic signal controller receives the infrared sensor through the control algorithm module. The traffic signal controller contains a control algorithm module, a yellow light module, a pedestrian signal light module and a traffic light control module group.

[0006] Furthermore, a traffic signal central controller and a main display panel are installed on the inner partition surface of the signal control chassis; and the traffic signal central controller is connected to the main display panel via electric wires.

[0012] The beneficial effect of the present invention is that the pedestrian priority intersection signal controller of the present invention uses a monitoring camera to capture the pedestrian traffic situation on the zebra crossing of the intersection, and transmits the signal that there are pedestrians on the zebra crossing to the traffic signal controller, which interrupts the traffic light control module group to control the change of the signal light, so that the yellow light module controls the signal light column on the current zebra crossing to light up the yellow light until there are no pedestrians on the zebra crossing.

[0018] Reference Figures 1 to 4 As shown, the utility model provides a pedestrian priority intersection signal controller, comprising: a signal control box 1, a signal light pole 2 and a traffic signal controller 4. The signal light pole 2 is distributed beside the signal control box 1, and the traffic signal controller 4 is installed inside the signal control box 1.

[0019] A T-shaped connecting frame 22 is welded to the column surface of the signal lamp pole 2, and infrared sensors 3 are installed on both sides of the T-shaped connecting frame 22. A monitoring camera 6 is installed on the cross bar end of the signal lamp pole 2 through a fixing frame 21. The traffic signal controller 4 receives the infrared sensor 3 through the control algorithm module 44. The traffic signal controller 4 contains a control algorithm module 44, a yellow light module 45, a pedestrian signal light module 46 and a traffic light control module group 47.

[0020] When the traffic signal light corresponding to a zebra crossing at an intersection is about to change, the surveillance camera 6 above this zebra crossing captures the pedestrian traffic situation on the zebra crossing and transmits the signal that there are pedestrians on the zebra crossing to the traffic signal controller 4. The traffic signal controller 4 interrupts the traffic light control module group 47 to control the change of the signal light, so that the yellow light module 45 controls the signal light column 2 on the current zebra crossing to light up the yellow light until there are no pedestrians on the zebra crossing. The signal light changes normally, which is convenient for warning passing vehicles to drive slowly and stop at any time, and facilitates the intersection signal controller to give priority to pedestrians, reducing safety hazards at intersections with large traffic volume, effectively extending the time it takes for vehicles to travel to the zebra crossing, and avoiding pedestrians who have already passed the zebra crossing being stuck in the traffic flow.

[0021] In this embodiment, a traffic signal controller 4 and a main display panel 41 are mounted on the inner bulkhead surface of the signal control cabinet 1 ; the traffic signal controller 4 is electrically connected to the main display panel 41 . A power distribution device 42 and a fault monitoring device 43 are mounted on the inner wall of the signal control cabinet 1 ; the power distribution device 42 is electrically connected to the traffic signal controller 4 .

[0022] As a preferred embodiment, the controller 4 in the traffic signal collects the sensing signal transmitted by the infrared sensor 3 in the pedestrian waiting area of ​​the intersection through the control algorithm module 44 to calculate the pedestrian flow, thereby intelligently extending or shortening the signal light transition time and alleviating traffic congestion.

[0023] In this embodiment, a remote transmission device 5 is fixed to the inner wall of the lower end of the signal control chassis 1, and a surveillance camera 6 contains an image recognition module 61. The remote transmission device 5 is electrically connected to the traffic signal controller 4. The yellow light module 45 and the red light control module assembly 47 electrically control the signal changes on the signal pole 2.

[0024] As a preferred embodiment, remote transmission device 5 is connected to a monitoring terminal to facilitate remote monitoring of the intersection signal control status. It can also remotely transmit line fault signals detected by fault monitoring device 43 to the monitoring terminal. Traffic light control module group 47 facilitates controlling the normal red and green transitions of the signal light on signal post 2. Amber light module 45 facilitates controlling the yellow light on signal post 2.

[0025] In this embodiment, the side end of the fixing frame 21 is screwed and fixed to the crossbar of the signal lamp post 2 through the mounting member 23 , and the monitoring camera 6 is fixed to the lower end surface of the fixing frame 21 .

[0026] As a preferred embodiment, the surveillance camera 6 is located above the zebra crossing at the intersection to facilitate monitoring of pedestrians passing through the zebra crossing. When the signal light on the signal lamp post 2 at the zebra crossing is about to change, the surveillance camera 6 captures and identifies whether all pedestrians on the zebra crossing have passed. When all pedestrians have passed, the signal light of the signal lamp post 2 is controlled to change normally. If not all pedestrians have passed, the signal light of the signal lamp post 2 turns yellow.

[0027] The pedestrian priority intersection signal controller of the utility model can effectively solve the problem that when the signal light of the existing intersection changes, pedestrians who fail to reach the opposite side in time on the zebra crossing are easily caught in the traffic flow with the green light, which creates a safety hazard. It is convenient to warn passing vehicles to drive slowly and stop at any time, and it is convenient for the intersection signal controller to give priority to pedestrians, reducing the safety hazards of intersections with large traffic volume, effectively extending the time it takes for vehicles to travel to the zebra crossing, and avoiding pedestrians who have already passed the zebra crossing being caught in the traffic flow. The utility model is suitable for pedestrian priority intersection signal controllers.
