Problems solved by technology

[0003] At present, although some urban intersections in my country are equipped with voice prompts, face tracking and recognition, and automatic recording systems for running red lights on the basis of ordinary traffic lights, the number is small and lacks targeted unified management. The main problems are: (1 ) The rules for non-motor vehicles passing at the intersection are not clear, and the default is the same as that of motor vehicles going straight in the same direction, resulting in insufficient passing space and time and poor sight distance; (2) Large vehicles on the motor vehicle lane easily block the sight of small vehicles behind , resulting in the cars behind not being able to make timely judgments on the situation of signal lights; (3) Pedestrians herding violations are serious; (4) The traffic organization design at intersections is mainly based on the traffic needs of motor vehicles, and does not fully consider the traffic needs of non-motor vehicles and pedestrians

Embodiment 1

[0029] Embodiment 1: see figure 1, a signal light control device for preventing red light running near an intersection, the control device includes a smart solar panel, a virtual curtain wall projection device, a curtain wall sensing and illegal detection device, and the virtual curtain wall projection device, curtain wall sensing and illegal detection device are arranged in On the smart solar panel, the smart solar panel device includes a base 2, an electric box 3 (including a photovoltaic controller and a storage battery), a support 6, a connecting plate 7, a support plate 8, a solar cell panel 9 and a protective glass 10; 1 is connected to the base 2, the lower end of the projection column is fixedly connected with an electric box 3, the inside of the electric box 3 is provided with a photovoltaic controller 4, the top of the projection column is fixedly connected with a bracket 6, and the top of the bracket A connecting plate 7 is fixedly connected, the bottom of both side...

Embodiment 2

[0030] Example 2: see Figure 1-Figure 9 , a control method of a signal light control device for preventing red light running near an intersection, the method is as follows:

[0031] Step 1: Determine the geometric physical model and signal control scheme of the intersection;

[0032] Step 2: Install the equipment at a suitable location at the intersection;

[0033] 2.1) Place the projection columns containing the fog screen machine and the regulator system at the four corners of the intersection. The channelized intersection can be installed on the pedestrian safety island. Each projection column has two working surfaces, of which A surface ( Red) controls adjacent motor vehicle entrances and non-motorized lanes, and side B (green) controls adjacent vertical sidewalks;

[0034] 2.2) In order to ensure the normal operation of the signal wall, the curtain wall sensing and illegal detection device, smart solar panel and high-definition camera are installed together. The variou...

Abstract

The invention relates to a signal light control device for preventing the behavior of running a red light near an intersection. The control device includes an intelligent solar panel, a virtual curtain wall projection device, a curtain wall sensing and illegal detection device, and the virtual curtain wall projection device, a curtain wall sensing and illegal detection device. Set on projection poles. The invention is suitable for signalized intersections with large traffic and pedestrian flows. The projection device projects a dynamic curtain wall with color prompts to replace traditional light pole or column traffic lights. Traffic managers can adjust the curtain wall according to the specific conditions of the intersection. Position, width and height for parameter adjustment settings. Due to the use of air projection and interactive technology, when some violators run red lights or have traffic accidents, emergency measures such as voice and text warnings or red flashing prompts can be made by adjusting the preset screen.

Description

technical field [0001] The invention relates to a control device, in particular to a signal prompt and warning device for preventing red light running near an intersection, and belongs to the technical field of traffic signal control and projection. Background technique [0002] Urban road intersections are important nodes of urban traffic, and a large number of pedestrians, non-motor vehicles and motor vehicles need to pass through the intersections during travel. Intersections are high-incidence points of urban traffic accidents, and the proportion of red light running at intersections is particularly prominent among the causes of accidents. Therefore, it is necessary to study the prevention of red light running. [0003] At present, although some urban intersections in my country are equipped with voice prompts, face tracking and recognition, and automatic recording systems for running red lights on the basis of ordinary traffic lights, the number is small and lacks targe...
