Build a "brain" highway monitoring

Recently, the Hebei Communications and Transportation Department issued the “Strategy for the Development of Intelligent Transportation in Hebei Province (2013-2020)”, proposing that the development goal of intelligent traffic construction is: By 2020, an intelligent transportation system that can basically meet the development requirements of modern transportation industry in Hebei Province will be built. The system strives to enter the nation’s intelligent traffic construction at the end of the “Thirteenth Five-Year Plan” period, and takes the lead in modernizing transportation.

Hebei deploys intelligent transportation plan, high-speed meteorological warning

The Hebei Communications and Transportation Department issued the “Strategy for the Development of Intelligent Transportation in Hebei Province (2013-2020)” and proposed to build an intelligent transportation system that can basically meet the development requirements of the modern transportation industry in Hebei Province, and strive to enter the national intelligent transportation construction in 2020. , Took the lead in modernizing transportation.

The eight tasks of the intelligent traffic construction in Hebei Province are to improve the monitoring and emergency disposal capabilities of highway networks at provincial and municipal levels in terms of intelligent traffic control and management, and to achieve all-round monitoring, supervision and intelligence of ships, waterways and ports. Command and efficient dispatch; In the area of ​​intelligent traffic safety protection, improve the fine meteorological warning level of highways and key channels, and promote the establishment of an emergency linkage and rescue service system; in terms of integrated traffic information services, the coverage of urban and rural areas and multiple modes of transportation shall be formed. The comprehensive traffic information service system; In the intelligent public transportation management, an urban passenger transportation intelligent coordination service system covering public transportation, subways, taxis, and integrated hubs has been established; in the aspect of freight organization management, document information sharing for various modes of transportation has been realized. And integrated customs clearance services; in the aspect of integrated transportation electronic payment, it improved the networked charging system to form an inter-regional and multi-mode integrated transportation electronic payment system; and in the area of ​​intelligent transportation standardization, it strengthened the application and service standards of transportation network operation monitoring and other applications. And formulating; in intelligence In the area of ​​transport industrialization, we will create an environment for intelligent transportation industry development and promote the formation of a smart transportation industry system in the province.

Intelligent Transportation Highway Application

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 .

Traffic flow control on the expressway entrance ramp, use of the communication with the monitoring center and the signal at the entrance ramp, intelligent supervision of the on-ramp traffic flow; closed-circuit television monitoring, using closed-circuit television cameras, real-time monitoring of illegal vehicles, found problems The emergency mechanism can be started in time for processing; the electronic police system uses video surveillance, speed measurement, automatic control and other technologies to achieve off-line traffic violations.

Intelligent transportation system is recognized as one of the effective methods to solve traffic problems. The intelligent transportation system aims to improve the efficiency of traffic operation and reduce the occurrence of traffic accidents. The idea of ​​developing intelligent transportation makes people from the traditional road maintenance alone. The model was disengaged, trying to use high technology to strengthen the links between people, cars, and roads in order to improve the effectiveness of the transportation system.

Intelligent Analysis: Build a "Brain" Highway Monitoring

With the development of network monitoring and high-definition trend of highway monitoring systems, the massive information filtering and storage requirements brought about by the system are all in urgent need of solution. How to extract useful information from massive data and improve monitoring efficiency may require relying on intelligence. Video analysis function to complete.

At present, 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.

Of course, the future intelligent analysis of highway video surveillance goes far beyond these, and it will become more in-depth with the complexity of traffic information. In addition, it is worth noting that the future of intelligent video surveillance is based on digital, networked video surveillance, and the networking of expressways will directly affect the application scale and application level of intelligent analytics. Therefore, the development and construction of future freeway monitoring systems will be driven by the development of networking, high-definition, and intelligence.
