High-speed vacation free traffic brings great convenience to the owners, but due to the large number of people and vehicles in the double holidays, high-speed traffic jams and even traffic accidents have become hidden dangers. For various problems, the security industry seems to be playing its own advantages to improve traffic safety performance and avoid the risk of traffic accidents.

Monitoring, "God's Eye" to "protect driving"

Xiao Bian first thought of the monitoring application.

Surveillance is not only to supervise the safe driving of drivers, but also to control the occurrence of accidents from the source. On the other hand, through monitoring, we can clearly and timely grasp the traffic information, rationally guide the flow of traffic, make traffic more accessible, and relieve traffic pressure.

At present, the implementation of China's high-speed monitoring front-end is mainly "standard definition, high-definition supplemented" model, the overall work is not bad. However, there is a trend to further increase the density of monitoring sites. Xiao Bian asked professionals to learn that point-to-point surveillance distance monitoring 500 meters away from the monitoring, 1 km monitoring, 2 km monitoring is the future of the highway video surveillance of several options, the investment of each adjacent point selection program is basically Multiplied by the increase in the number of monitoring points, so the choice of a good video surveillance is the key to the entire system investment. From the perspective of the existing camera lens imaging, basically about 500m is its best imaging range, and the imaging effect is greater than this distance, so monitoring in a single 500m direction is definitely the best solution. However, this proposal is the largest investment program, so it is generally recommended two-way monitoring 1km, centered around the central isolation zone, the use of vertical poles about 15m-18m (according to the road conditions to calculate the height) two-way shooting two directions) .

Intelligent Transportation: High-speed congestion management In the Intangible Intelligent Transportation System (ITS), advanced technologies such as computer data processing, automatic control, information, data communication and electronic sensing are integrated and used in a transportation management system to establish A comprehensive, large-scale, real-time, accurate, and efficient integrated transportation and management system.

The application of intelligent transportation systems on highways is realized through real-time monitoring and information transmission processing.

The ETC system can reduce the time delay and labor consumption caused by the traditional charging mode and improve the traffic capacity of the lane; the road traffic sensor can monitor the pressure and stress conditions of the road in real time and transmit the monitoring data at the same time. To the management center, real-time understanding of road conditions to provide comprehensive information for the conservation department; variable speed limit signs and variable information signs, real-time display of road conditions and accidents along the way, timely release of speed limit information, dynamic management of traffic flow .

Intelligent assistance for expressway traffic is to control the traffic flow on the on-ramp road, use and monitor the traffic of the center and the signal lights at the entrance ramps to implement intelligent supervision on the traffic flow on the on-ramp road; closed-circuit television monitoring, using closed-circuit television cameras, The real-time monitoring of illegal vehicles, the discovery of problems can promptly start the emergency mechanism for processing; electronic police system, the use of video surveillance, speed, automatic control and other technologies to achieve off-line traffic violation punishment.

The idea of ​​developing intelligent transportation has separated people from the traditional mode of building roads and cars alone, trying to use high technology to strengthen the links between people, cars, and roads so as to improve the efficiency of the transportation system. In theory and practical applications, the intelligent traffic system also achieves the effect of improving traffic operation efficiency and reducing traffic accidents.

Intelligent transportation is not just testing, but it can be analyzed on its own. The intelligent analysis that can be carried out for highway video surveillance includes license plate recognition, traffic event detection and analysis, and video traffic status detection. License plate recognition has been maturely applied in highway toll collection systems. It can automatically register, verify, monitor, and alarm the passing vehicles. Intelligent video analysis of traffic incidents mainly includes: object movement monitoring, object detention monitoring, sudden appearance monitoring, moving path monitoring, and object monitoring. Intelligent analysis of traffic incidents In the captured image area, real-time analysis of vehicle speeding, low speed, retrograde, and object leftovers can be performed for different lanes and traffic conditions. When a traffic accident occurs, the system can quickly link alarms and videos for traffic. Security provides protection. Traffic condition detection is to automatically identify the traffic status of the road segment through real-time data collected by the front-end. When congestion or congestion of road traffic is detected, the system automatically alarms, and statistics of congestion data are generated, and traffic is distributed to monitoring centers at all levels through the platform. information.

Technology brings great convenience to human life. The security industry is closely related to science and technology and is closely related to our lives. Xiao Bian thinks that the security industry's application for traffic will surely continue to develop in the future. Such development has always been aimed at alleviating traffic pressure and reducing the incidence of traffic accidents. Of course, we must also not forget to follow the traffic rules and enjoy civilized travel while enjoying safety protection.
