Under the promotion of the Jiangsu 320 project, cities such as Chengdu, Guiyang, and Wuhan started large-scale intelligent transportation construction or planning. The new round of traffic monitoring follows the technical development direction of video surveillance. The technologies adopted are high-definition, intelligent, and networked, and the existing systems have been rationally transformed and integrated.
The trend of large-scale monitoring of the network was led by the Ministry of Public Security on the basis of carrying out the construction of urban alarm and monitoring systems. The “3111 Project†was put forward. In 2005, the first batch of pilot projects identified 22 “3111 Projects†pilot cities, and the second batch in 2006. The pilot project initiated 66 prefectures and 419 cities, counties, and neighborhoods. At the same time, three batches of strong science and technology police projects have also been launched. The video surveillance system project has entered an unprecedented wave of construction, and governments and departments at all levels have invested in the construction of a safe city with a high degree of enthusiasm under the guidance of unified planning and unified construction. As an important construction unit for the construction of a safe city, the traffic police department also actively conducts traffic monitoring and construction of urban roads, expressways, and entrances and exits. Intelligent transportation network is the trend of the times.
1. It is the need to break down the block and unify the construction. The vertical and horizontal construction of the monitoring system greatly limits the system's role. For example, at the same monitoring point, the security surveillance cameras of the public security department and the road monitoring of the traffic police department may appear at the same time. Cameras, urban management surveillance cameras of urban management departments, etc. In some cases, cameras in different departments are even in the same monitoring range. Such construction has caused great inconvenience to monitoring and management, and it is a huge waste of human resources, equipment, and funds. One of the main reasons for this kind of redundant construction is the lack of unified planning in the absence of networking, so that it is impossible to form a unified management from bottom to top. Each department is an independent system and cannot effectively coordinate and cooperate. This kind of construction method only pays attention to the vertical development and neglects the horizontal cooperation, which makes the monitoring effect greatly reduced. The large-scale traffic monitoring network will help to break the restrictions of this segmentation and eventually create a coordinated and unified system that is built by one person, used by multiple people, and triggered at one point and coordinated by multiple points.
2. Need for intelligent traffic networking applications The traffic monitoring system mainly completes the monitoring of road traffic conditions. Most traffic monitoring centers and sub-centers only monitor the operation of the road through a small number of surveillance cameras placed along the road. It is difficult to quantitatively analyze and evaluate the traffic capacity and operational indicators of the road, and thus it is not possible to publish relevant traffic guidance and control. Information makes the function of the monitoring system not play well. The large-scale traffic monitoring network is conducive to the integration and linkage of traffic monitoring and bayonet, traffic violation, "6-in-1" platform, traffic guidance, command and dispatch, and other subsystems, which is conducive to the use of multiple technical means for the release of comprehensive traffic information.
3. It is an important part of the public security work that the need for public security intelligence work is coordinated between the traffic control and the public security departments. The public security “intelligence†concept extends the function of public security intelligence from the actual service to various areas of public security work, including traffic management. With the rapid development of China's economy, the problem of low levels of transportation management and service is becoming increasingly prominent. Integrate traffic management information into the comprehensive intelligence information platform of the public security and expand the scope of application of public security intelligence to key drivers, vehicles, transport units, early warning of major traffic accidents, distribution of police on the road, and decision-making in traffic control departments. In the process of intelligence gathering, information on drivers and vehicles in the traffic management process can be used as an intelligence source. The theft of motor vehicles, illegal motor vehicles, intersection cameras, vehicle drivers, etc. can all provide information. The value of such information is Criminal investigation will play a vital role.
Traffic management information is an indispensable part of public security “big intelligenceâ€, and it is necessary to exchange, share and cooperate with other police types in intelligence resources. In the current situation of not being connected to the Internet, the traffic management and intelligence research and judgment are on different networks. In different systems, the public security department needs to retrieve information in the corresponding traffic management system based on the clues of the case and carry out information retrieval. After the retrieval results data, pictures, videos and other information are exported through the hardware medium and then imported into the intelligence analysis platform for analysis, it takes a lot of police power and time when a major case or case arises. The resources are expensive to consume and at the same time, due to this efficiency. Low, often misses the best opportunity to solve the case.
Car networking is a key development direction In recent years, with the rapid development of the national economy, the automobile industry has continued to develop rapidly as a pillar industry. Cars have become ordinary commodities into ordinary people's homes. Practical development of everything is a double-edged sword. The huge traffic has brought great inconvenience to the people's normal life. On the one hand, the state has also increased infrastructure construction (highway and public transportation), and at the same time it has gradually increased the current level of traffic intelligence.
From a technical point of view, the car network is divided into two technical parts, namely, RFID technology based on on-board applications and ITS intelligent traffic management technology based on traffic management. However, from the perspective of the car networking system architecture (pictured), in addition to the above-mentioned vehicle-based application of RFID technology (perceptual layer) and TS intelligent traffic management technology (application layer), there are communication technologies (network layer). First of all, when we talk about RFID (sensing layer), most friends who are familiar with RFID are aware that the most important feature of RFID is its non-contact recognition capability.
This allows the object to be counted and managed even if it does not stay when it is passing quickly. This is undoubtedly the most convenient and most reliable for traffic management. Secondly, for ITS (application layer), I am afraid that everyone may not understand as much as RFID. This is short for Intelligent Transportation Technology. It integrates the most advanced sensing technology, communication technology, data processing technology, automatic control technology, and information release technology into the existing traffic control system.
For the individuals of the vehicle, the introduction of the Internet of Vehicles technology not only can make the vehicle more smooth in the process of passing, but also greatly enhance the information level of the vehicle itself and the information exchange level of the vehicle. This includes both the exchange of vehicle data, but also includes personnel exchanges. Under such technical support, whether it is the vehicle's safety management capabilities, or vehicle condition management capabilities, or the vehicle's interactive, recreational applications, it is also a very big supplement. It is in such a static and dynamic mode, together with the role of a stable and efficient communication network, that traffic management will enter a new era in security.
The integration of traffic creates the term “intelligent trafficâ€. We have already referred to it many times. Different people have different understandings about its construction. However, the common point is that in the subsequent urban construction, it will be Into the formal construction. The personal conditions required for traffic integration are already in place: private cars, public transportation (buses and coaches), car rentals, and the more and more common electric cars. However, these modes of transportation in the market usually exist in closed transportation systems. These transportation systems are almost independent of each other, so users cannot quickly and easily switch between various modes of transportation, and (markets) lack the concept of transportation integration. All cities need to develop this area, especially the largest 30 cities. About 180,000 people enter these 30 cities every day, which is a major challenge for the urban transport system. Optimizing travel methods will not only benefit the environment, but also improve the quality of life in these large cities. In addition, 266 billion U.S. dollars will be saved each year. These costs are the additional costs of poor transportation.
For the dissemination of intelligent transportation, it should be noted that many of the conditions are actually mature. The first is the widespread use of smart phones. With more than 1 billion smart phones in the global market, users can now access important real-time information anytime, anywhere. Experts predict that the number of smartphones will double in the next two years.
In addition, the construction of intelligent transportation will certainly drive the development of other industries. The relevant report shows that the market for car networking is expected to reach US$21.82 billion in 2013. This will lead to the development of a large number of upstream and downstream industries and create more economic value.
