Abstract: With the rapid development of the social economy, people's living standards continue to improve, the number of various types of automobiles has increased significantly, and it is becoming more and more important to improve traffic efficiency. At present, countries all over the world have invested a lot of manpower and material resources to study the Intelligent Transportation System (ITS). As an important part of ITS, the electronic police system plays an important role in regulating driver behavior, eliminating traffic accidents, improving traffic enforcement and road traffic. Starting from the actual problems of the existing electronic police system, it has proposed its own solutions in system control, vehicle detection and system. The structure of the video detection system and control system based on embedded system is introduced.

0 Preface

With the development of China's economy, motor vehicles continue to grow, and the growth of existing roads and other hardware facilities has not been able to meet the growing traffic problems. Intelligent Transportation Systems (ITS) are gaining more and more attention.

The so-called Intelligent Transportation System (ITS) is a kind of comprehensive and comprehensive application of information technology, data communication transmission technology, electronic sensing technology and computer processing technology to the entire ground traffic management system. A comprehensive, real-time, accurate and efficient integrated transportation management system. In recent years, ITS has been widely used in urban traffic management, and has achieved good results in mitigating road traffic, preventing traffic violations and accidents. This paper proposes a vehicle violation video detection scheme for ITS applications, especially the application of electronic police system, to adapt to the development needs of ITS.

1 Electronic Police System

The electronic police is mainly for the automatic monitoring and recording of traffic violations that are easily caused by vicious accidents at the intersection of the motor vehicles. It has achieved unattended and uninterrupted monitoring, and the evidence is fully correct, improving the accuracy and efficiency of traffic enforcement. The traditional typical electronic police system is usually composed of system control, illegal vehicle detection, shooting, transmission and auxiliary equipment.

At present, the general electronic police system mainly adopts a loop coil inductor and an enhanced PC-based IPC platform control mode. The inconvenient installation and damage of the toroidal coil and the poor adaptability of the IPC to the outdoor environment have caused great difficulties for the normal operation and maintenance of the electronic police. Therefore, the vehicle violation detection technology has a great influence on the high-precision and large-area promotion of the electronic police. It is an important part of the electronic police system and an indispensable component of the traffic management system.

2 Existing vehicle violation detection technology

Vehicle detector is an indispensable part of the traffic management system. It mainly provides various traffic parameters to the information processing and information release unit in the monitoring system through data acquisition and equipment monitoring. It is analyzed, judged and issued as a monitoring center. Information and the main basis for proposing control schemes. Commonly used traffic vehicle detectors mainly include loop coil detectors, ultrasonic or microwave (radar wave) detectors, infrared detectors, video detectors, and the like.

Comparing several detection methods, it can be known that ultrasonic or microwave (radar wave) detectors and infrared detectors use harsh conditions and are used less, mainly for manual detection. At present, the most common and frequently used is the loop coil video detector, but the video vehicle detector has the following technical features compared with the detector such as the induction coil:

(1) The video detector is easy to install and maintain, and it does not need to excavate the road surface, and has little impact on road traffic.

(2) The video vehicle detector can detect a large traffic scene area, and a single camera can simultaneously monitor multiple lanes, thereby reducing the number of sensors installed and performing vehicle tracking in a wide range.

(3) It can provide most of the traffic parameter information, including traffic flow, bicycle speed, average speed, and vehicle spacing.

(4) The obtained video and image information is very intuitive, human-readable, and can be saved. This provides a reference for the monitoring personnel to perform related operations.
