1. Project construction background

Article 47 of the "Law of the People's Republic of China on Road Traffic Safety" stipulates that when a motor vehicle is crossing a crosswalk, it should stop to give way when a pedestrian is passing the crosswalk; when a motor vehicle is passing a road without a traffic signal, it should be crossed Roads should be avoided.

To give courtesy to the zebra crossing, when there is a pedestrian passing on the zebra crossing, the driver should take a slow down or stop exercising. Active avoidance or courtesy of pedestrians is the respect of drivers for people, as well as the respect of life, and is a manifestation of the degree of urban civilization.

With the development of China's economy, the progress of society and the acceleration of urbanization, the traffic pressure on highways and urban roads is increasing. At the same time, the rapid economic development has brought a sharp increase in traffic flow, which The contradiction between "car and road" is becoming increasingly prominent. The resulting low traffic efficiency and frequent traffic accidents have become the main factors restricting the development of urbanization in China and affecting the quality of life of residents.

Intelligent transportation is considered to be an effective way to guarantee traffic safety, ease congestion problems, and reduce traffic accidents. "Integrated transportation and intelligent transportation" is also one of the key special projects in the "13th Five-Year Plan" of transportation technology. Foresight Industry Research Institute's "2016-2021 China Intelligent Transportation Industry Market Forecast and Investment Strategic Planning Analysis Report" pointed out: Intelligent transportation system is the future development direction of transportation system, it is the use of advanced information technology, data communication transmission technology, electronic transmission Sense technology, control technology and computer technology are effectively integrated in the entire ground traffic management system to establish a real-time, accurate and comprehensive transportation management system that is effective in a large range.

Compared with developed economies such as Europe, the United States, and Japan, there are still some gaps in the development of intelligent transportation in China. But we also have some of our own advantages, which can be summarized into three points: First, governments at all levels attach great importance to it. The second is that we can give full play to the advantages of late-coming. Third, China's smart transportation market has broad application prospects.

The application of smart transportation can maximize the operational capabilities of the transportation system, reduce traffic accidents, improve transportation utilization, and mitigate environmental pollution and energy consumption problems. Therefore, smart transportation in various cities and roads is the next development trend in China.

In road traffic safety accidents, many accidents occur on zebra crossings with poor visibility, especially when there is a high beam background at night. It is difficult for drivers to see the road surface clearly, which eventually leads to accidents. In order to avoid the above situation, it is necessary to provide a sidewalk indicator and control system that can be installed on the road surface or zebra crossing and has a warning function for drivers and pedestrians.

2. Product design basis of smart zebra crossing system

1. Requirements of national laws and regulations:

Article 47 of the Law of the People's Republic of China on Road Traffic Safety: When a motor vehicle passes a crosswalk, it should stop and give way when a pedestrian is passing the crosswalk; when a motor vehicle passes a road without a traffic signal, a pedestrian crosses the road Should be avoided.

2. The needs of smart city development:

Polite zebra crossing means that the driver should slow down or stop the pedestrians on the zebra crossing. Taking the initiative to avoid or polite pedestrians is a specific action that the driver respects pedestrians and respects life. It is also a manifestation of the civilization of a city.

Smart zebra crossing is a product of technological development, it is a replacement product for courtesy of zebra crossing, and it is the need of smart city development.

3. Connect with the future:

The digitalization of road infrastructure is the future development direction of cities and the prerequisite for the application of new products such as driverless cars and robot police in the future. With the development of artificial intelligence and the rapid progress of technological level, the digitization and wide application of basic information have become the focus of the industry.

3. Construction goals

1. Centralized control system for zebra crossing

The pedestrian and vehicle conditions of the zebra crossings in each area can be monitored and managed in a city-wide manner, or a single zebra crossing can be monitored.

Through the information transmission of the Internet of Things, information on the number of people and vehicles in the implementation area can be obtained in real time.

The flow monitor can be configured to identify the pedestrian vehicles at the intersection and take photos and videos. (Note: Corresponding functional modules can be configured according to customer needs)

Through video surveillance and snapping, snapping and feedback on the behavior of motor vehicles inadvertently passing pedestrians in front of the zebra crossing, providing a basis for the traffic license of the traffic management department. (Note: Corresponding functional modules can be configured according to customer needs)

Through the laser and video monitoring, the pedestrians crossing the red light at the crossroads are captured, and the face recognition system is used to identify the violators and promptly remind the violators. Data and photos are transmitted to the management platform through the Internet of Things information system for data statistical processing. After repeated violations, the data and photos can be submitted to the traffic management department as the basis for their execution. (Note: Corresponding functional modules can be configured according to customer needs)

According to the dynamic data changes of system statistics, it provides a basis for police force dispatching.

2. Wisdom zebra crossing

Through radar laser, infrared and other sensing equipment, the pedestrian crossing line is covered in full range, and whether a pedestrian passes on the sidewalk is sensed in real time.

When there are pedestrians passing on the sidewalk, light the "horse lights" on both sides of the zebra crossing, and remind the passing vehicles to slow down and slow down at night and in the case of poor lighting. Reduce or avoid traffic accidents.

Pedestrian detection information is sent to nearby driving vehicles, promptly reminding drivers to pay attention.

When a pedestrian or non-motorized vehicle crosses the road on the zebra crossing and is blocked by the cart, the marquee lights and jumps to remind the driver of the car in the blind zone of the second and third lanes to pass, reducing the "ghost probe" accident.

Can provide a variety of installation methods and lighting methods, lighting colors for customers to choose.

The product design has high reliability. The floor lamp for zebra crossing has a single-point compression capacity of 25 tons, which meets the load-bearing compression resistance requirements of all roads in the city. It reaches 120 ℃; its abrasion resistance is excellent, the average value is 2-10 times that of rubber materials; the waterproof performance is good, reaching the IP57 test standard.

The color of the light bar can be selected as red, green and yellow, and it can be set to cooperate with the traffic lights of the intersection.

Scan the blind area of ​​the right turn of the big truck at the intersection to remind pedestrians to pay attention to safety in real time. (Configuration according to demand)
