What laws did pedestrians violate by running red lights?

Pedestrians running red lights are the most common, most obvious, and most numerous traffic violations among pedestrian traffic violations. This kind of illegal behavior not only poses a great danger to the person of the traffic offender, but also hinders the smooth flow of the road and is a great inducement to cause traffic accidents. The "Pedestrian Running Red Light Capture Voice Warning Intelligent System" can very humanely warn passers-by to abide by traffic laws, reduce the incidence of accidents involving pedestrians running red lights, and improve citizens' traffic quality.

This system is based on image processing and pattern recognition technology and can provide law enforcement basis for pedestrians running red lights. The "Pedestrians running red lights capture voice warning intelligent system" provides reliable data for the evaluation of civilized traffic intersections.

According to statistics, in 2008, 265,204 road traffic accidents occurred nationwide, causing 73,484 deaths, 304,919 injuries, and direct property losses of 1.01 billion yuan. Among the roads where accidents occur, the accident rate and number of casualties are highest in straight sections, pedestrians and non-motorized vehicles running red lights. At present, pedestrians running red lights is the most common, most obvious and most numerous traffic violation among pedestrians.

According to statistics, 80% of the traffic accidents that cause death in our country are caused by pedestrians violating the rules. According to the traffic accident statistics of the Traffic Police Corps of the Shanghai Public Security Bureau, statistics from the Fourth Brigade of the Pudong New Area Traffic Police Detachment show that traffic accidents in Jinqiao Town are mainly concentrated on 10 primary and secondary roads in the central area, including Jinhai Road, Jingao Road, Donglu Road, and Jialin Road. within the area. Among the road traffic accidents that occurred in the central area of ??Jinqiao Town from 2005 to 2006, there were 132 road traffic accidents caused by drivers failing to yield as required, accounting for 53.9%; there were 75 traffic signal violations, accounting for 30.62%.

According to statistics, at a major intersection in a medium-sized city, if a non-motor vehicle violation occurs during commuting time, the traffic capacity of motor vehicles at this intersection can be reduced by 50%. According to calculations, every time a pedestrian runs a red light, urban management will have to pay at least 1 cent extra, and urban management of pedestrians running a red light will cost tens of millions of yuan a year.

"Pedestrians running red lights capture voice warning intelligent system", once a pedestrian runs a red light, the system will continuously send out voice prompts, and at the same time, the electronic screen will instantly play the captured pictures of pedestrians violating the law, enabling 24-hour monitoring, Recording, statistics and analysis are of positive significance for regulating the traffic behavior of pedestrians crossing the road, reducing traffic accidents caused by pedestrians running red lights and improving citizens' awareness of traffic safety. Hebei Wuxing Electric Power Equipment Co., Ltd. Pedestrian running red light capture voice warning intelligent system 1. Project background

"Pedestrian running red light" has always been a focus and difficulty in urban management in my country. After years of governance, pedestrians' violations of red light violations have been reduced in developed cities such as Beijing and Shanghai, but there is still a big gap between the traffic management level of developed countries such as the United States and Germany. In response to this situation, six departments including the Ministry of Public Security, the Central Civilization Office, the Ministry of Education, the Ministry of Justice, the Ministry of Transport, and the State Administration of Work Safety issued an initiative to “abandon bad traffic habits and travel safely and civilly.” However, in reality, there are still a considerable number of pedestrians who have weak awareness of law-abiding and have a fluke mentality when it comes to breaking red light violations. In addition, the relevant government departments are not enough to popularize legal knowledge among the people, as well as the incomplete and unscientific municipal road facilities, and the lack of relevant evidence collection measures, etc. have also caused the illegal behavior of running red lights to be repeatedly prohibited.

It is against this background that the "Pedestrian Running Red Light Capture Voice Warning Intelligent System" is developed by Hebei Five Star Electric Power Equipment Co., Ltd. using video collection, intelligent facial feature recognition, streaming media technology and image search technology. An all-in-one smart urban transportation solution. By deploying this system, when pedestrians take the first step to violate the rules by running a red light, they will hear intelligent voice warnings around them (for example: Comrades wearing XX colors, please do not violate the rules!). At the same time, smart cameras will freeze the violators. Shoot and display the image of the violator on the warning sign in front of him. If the violator continues to move forward despite being dissuaded, the system will automatically record and save the violator's violation as evidence of traffic violation penalties.

At the same time, through the intelligent image search system, the historical violation record of the violator can also be queried. For those who refuse to change despite repeated admonitions, they can be further held accountable, achieving a good deterrent and warning effect. The implementation of this system will greatly improve the phenomenon of pedestrians and non-motor vehicles crossing the road arbitrarily, reduce the occurrence of traffic accidents, and make "Chinese-style crossing the road" no longer a street scene.

2. System Introduction

1. Product Principle

The topology diagram of the voice warning system for catching pedestrians running red lights (hereinafter referred to as the system) is as follows

When the red light turns on, the high-definition digital camera monitors the location and status of pedestrians on the zebra crossing in real time and transmits it to the host through the wireless transmission module in real time. A host equipped with a machine vision analysis module analyzes the image in real time. Once it is determined that someone has started running a red light, it will immediately warn pedestrians through a high-power speaker. People who run red lights are displayed on a large outdoor screen.

At the same time, the host controls the camera to focus and enlarge the face of the intruder to take pictures and store them in the database. Administrators can perform search, comparison and other management operations on light trespasser data.

2. Main components

U high-definition camera is responsible for collecting image information of crosswalks at intersections, and transmits real-time video to the host through the wireless transmission module. The camera can automatically turn on and off the lighting flash according to the ambient brightness. The camera uses a CCD sensor with 600 lines of resolution, and high-definition ensures clear images.

u Wireless transmission module encodes camera images in real time, compresses them into digital signals and then transmits them to the management host. It also receives PTZ control commands from the host to control the camera focus.

u Host The host receives the video signal output from the wireless transmission module into the memory, and then performs preprocessing, identification and analysis. Once a red light violation occurs, the system will immediately alert and dissuade the driver through voice, and store incident-related information in the database. Real-time images of red light violations will be displayed on an outdoor LCD screen, which will serve as a reminder and education to surrounding pedestrians. The host generally needs to be placed indoors or placed outdoors in a dust-proof and rain-proof control cabinet. Each intersection only requires one host, which can support traffic monitoring in 8 directions of the intersection.

u Outdoor display screen: Color 22-inch LCD screen or large-size LED, real-time display of the image of the person running the red light on the crystal display screen, which has a certain prompting and educational effect on surrounding pedestrians. The number of display screens can be customized according to actual needs, and there are three installation options: 1, 2, and 4 display screens.

1. One outdoor display screen at each intersection, usually installed on the side close to the police station.

2. Two display screens are placed diagonally at the intersection.

3. Four display screens, one at each of the four corners of the intersection.

U outdoor high-power speakers?

The speakers receive the voice signal from the host and broadcast with high power to alert, dissuade and warn people who run red lights. The placement method is the same as the display screen.

uMachine Vision and Face Detection System (Control Module)

The vision system uses machines to replace human eyes for measurement and judgment. The vision system refers to converting the captured target into an image signal through a machine vision product (i.e., image capturing device, divided into CMOS and CCD), and transmits it to a dedicated image processing system, and converts it into an image signal based on pixel distribution, brightness, color and other information. Digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions based on the discrimination results.

The analysis and face detection module uses OpenCV as the core of machine vision. After 15 years of evolution and development, the OpenCV system has the characteristics of stability, efficiency, and high recognition accuracy. It is especially suitable for target detection and tracking, and face recognition. and vehicle feature recognition.

3. Application effects and main functions

The system regulates the traffic behavior of pedestrians crossing the road through voice warnings and instant warnings of illegal picture captures, and plays an important role in reducing the number of pedestrians crossing red lights indiscriminately. It is of positive significance to cause traffic accidents and improve citizens’ awareness of civilized traffic.

The system has 24-hour monitoring, recording, statistics and analysis functions for pedestrians running red lights and violating regulations. Through an efficient face image matching algorithm, the system can retrieve violators who have repeatedly run red lights, and correlate the video and image information of previous red light runs, providing strong evidence support for the traffic police to take punitive measures against them.

The system uses a large-size, high-brightness outdoor display screen, which can not only expose illegal pictures of pedestrians in real time, but also play public service advertisements, traffic information, traffic control information, traffic slogans, etc. during the green light period. , which enhances the system’s role in promoting traffic civilization and improving the quality of citizens, and has good social benefits.

3. Product features 1. Leading design concept

1) Most of the existing similar products on the market adopt single display and single audio source designs. In this way, the system can only display the intersection situation in one direction. Due to the distance and surrounding environment limitations, the voice prompts cannot be transmitted remotely. While such structural design is reducing costs, it also sacrifices the practicality of the system. The actual situation at the intersection is that there are many cars, many people, and the environment is noisy. This determines that it is almost impossible for pedestrians to notice the large screen outside their field of vision, let alone the content displayed on the screen.

In view of this situation, this system adopts a multi-display and multi-sound source design. One to four display screens and speakers can be set up according to the actual situation, so that violators can immediately hear targeted warning sounds. , see the picture of his violation, and achieve the purpose of terminating his violation in time.

The control module of this system can realize intelligent switching between audio and video, making the video images and voice prompts clearer and more intuitive, which greatly improves the efficiency of the system.

2) At present, most products of the same type use about 20-inch LCD monitors as external amplifiers. The display effect is not intuitive and cannot achieve warning and publicity effects well. Our company uses large-size LED screens as display terminals, which can clearly remind violators and record and play violations, thereby achieving good warning and dissuasion functions.

3) In terms of video collection, our company uses a high-definition camera with IR-CUT technology, which can improve the image quality and clarity by more than 30%, ensuring clear captured images under severe weather conditions. 2. Complete software functions

1) Humanized warning function. Most of the similar software on the market use the same method to prompt violators, but the deterrent force is not enough to attract the attention of violators, and the deterrent effect is not obvious. This system adopts intelligent recognition mode, which can effectively analyze the physical characteristics of the violators and make targeted prompts such as: "Comrade in red clothes, please do not run the red light", dispelling the "law is not responsible" for violators. The lucky mentality of the public greatly improves the success rate of warnings.

2) Powerful statistical analysis function. This system can be customized according to users and generate trend charts of traffic violation occurrences at different time periods, at different intersections, and by different officers on duty. At the same time, based on the penalty information, a comparative analysis chart of the punished person's age, education, occupation, etc. can be generated to formulate corresponding measures for urban traffic managers and provide strong decision-making support.

3) The system provides accurate face recognition function. Based on the intelligent analysis of the images captured by the system, the historical violation information of the violator can be found and related videos can be associated, so that law enforcement officers can have evidence to rely on.

4) The system provides a remote query interface. Managers can view the red light monitoring images of pedestrians at various intersections in real time through the remote Internet and query relevant data.

China News Service, Shijiazhuang, October 10 (Liu Mingyi) Recently, at some intersections in Shijiazhuang, Hebei Province, "artifacts" for capturing pedestrians running red lights have appeared. Many pedestrians passing by these intersections said that this capture The system has a certain warning effect on passers-by running red lights, and will also regulate their own behavior for this purpose.

On the 10th, at the intersection of Zhongshan Road and Qingyuan Street in Shijiazhuang, an "artifact" was installed to capture pedestrians running red lights. The reporter learned that the "artifact" was called the automatic identification and capture system for pedestrians running red lights. It would beep every minute or so. There will be a beeping sound, accompanied by a voice prompt: "Walk on the zebra crossing, don't run the red light." The intersection monitor can reflect the video images of pedestrians on the display in real time. If there are still citizens passing the zebra crossing when the signal light is red, the system will automatically capture their images and form a photo and send it to the electronic screen. In this regard, Mr. Cao, a motor vehicle driver, said that pedestrians running red lights at will pose a great safety risk to motor vehicle drivers, and many traffic accidents have also occurred as a result. After the capture system is installed, pedestrians will consider face issues and do not want their bad habits to be captured and affect their image, so they will definitely standardize their behavior.

Pedestrian Ms. Li said that installing this "artifact" will allow more people to stop and wait for the red light, avoiding the embarrassment of "only one person is waiting when the red light is on", and will form a good habit, allowing more people to stop and wait for the red light. More and more people are consciously obeying traffic rules.

However, some citizens said that the display screen of the automatic recognition and capture system for pedestrians running red lights installed on the streets of Shijiazhuang is too small, and many people do not know its existence, so it cannot serve as an effective warning. They hope that the traffic control department can This "artifact" will be further improved to increase the guarantee of people's safe travel.
