Intelligent traffic application background analysis
In 2014, road congestion became one of the most criticized “urban diseases” in large and medium-sized cities in China. On the huge road traffic network, how to deal with traffic jams caused by traffic accidents or accidents, how to make the signal system of intersections clever, and the road traffic between cities is changing, and intelligent traffic appears. It is the development direction of the future transportation system. Its goal is to establish an all-round, accurate, and efficient integrated transportation system to ensure safety, improve efficiency, improve the environment, and save energy. On the basis of more perfect road facilities, the advanced transportation theory and high-tech integration will be applied to the whole process of road transportation, strengthen the connection between vehicles, roads and people, and collect and analyze traffic data intelligently. And feedback to the operator or driver of the system. The system operator or driver responds quickly with the processed traffic information to improve traffic conditions. Intelligent transportation emphasizes systemic, real-time, interactive information exchange and extensive service, which is essentially different from traffic management and engineering in the original sense. Intelligent transportation has its special application background, which can be said to be the product of market demand.
Rapid economic development has caused deterioration in traffic conditions and the environment
China has experienced rapid development of reform and opening up for more than 30 years, and urbanization and automobileization have developed rapidly. The urbanization process has further strained urban transportation resources. It is expected that China's urbanization will rise from the current 45% to 60% in the next decade, which will further promote the development of transportation and automobile industry. However, urban transportation resources will be even more tense. The number of motor vehicles is growing at a rate of more than 10% per year. It is expected to exceed 200 million vehicles this year. In the last two years, Beijing has challenged the carrying capacity of the road with the speed of adding 10,000 vehicles per week.
The air quality of Chinese cities continues to deteriorate, and motor vehicle exhaust has become a major source of pollution. The contribution rate of pollutants emitted by motor vehicles in some large cities to many air pollution indicators has reached more than 60%, which is seriously jeopardizing people's health. Traffic congestion, declining speed and poor vehicle conditions, and low technical performance of vehicles have made China among the top ten cities with the most air pollution in the world. The bottleneck of traffic development has become an important factor restricting the development of China's cities. In terms of road management, The regional restrictions on administration and investment, the establishment of highway management and ordinary highway management in China is based on the administrative area. According to the segment management mode, no unified resource management system is proposed on the infrastructure; in the aspect of automobile management, no unified Vehicle management system. Most of China's traffic informatization construction is only to solve some specific and partial problems during construction. Therefore, each system basically exists independently and presents an information island model under the network background.
Insufficient current traffic monitoring
The first is that traffic illegal drivers cannot be identified. Confirming the illegal party is a problem. Due to the clarity of the camera, off-site law enforcement can only confirm the fact that the vehicle is illegal. The specific driver is unknown. In actual operation, even if the driver is illegal, the driver will deny it. Admit that he is the owner of the car, so that the punishment of the corresponding certificate and a series of management measures (such as deductions, re-examination) are not enforced, the seriousness of the law is challenged. In addition, due to the transfer, sale, mortgage, etc. of the vehicle will cause changes in the vehicle owner registration, but often many vehicles have not handled the procedures of “transfer” and “transfer”, and there are certain difficulties in the decision and implementation of the penalty.
Secondly, the maintenance of traffic monitoring equipment is not guaranteed. There are heavy construction and light maintenance phenomena in various places. In some areas, the monitoring equipment has no maintenance funds, and it has become a device for "work with illness" or for a long time.
Finally, some regional traffic monitoring systems have not been verified or verified by the relevant state departments. In most parts of the country, the national compulsory verification equipment can be regularly verified. However, in some areas, the technical supervision department only verifies the lightning protection, instead of verifying the entire monitoring system, so there is systematic error, which affects law enforcement. Serious. In addition, some areas use video detection to measure speed, which is currently controversial. The principle of video detection is detected by the amount of video change of the virtual coil. The video change is greatly affected by external light or light, and the detection accuracy cannot be guaranteed.
Transportation is the lifeblood of economic development. Therefore, the urgent problems to be solved in intelligent transportation mainly focus on how to alleviate road pressure, reduce accident rate, improve public transportation services and save energy and reduce carbon.
Three areas of intelligent traffic monitoring applications
To solve the above-mentioned road traffic problems that need to be solved urgently, video surveillance technology has been introduced into the field of intelligent transportation and plays a huge role.
Automatic highway monitoring
The highway monitoring system is an important means to realize the modern management and control of highway transportation, and to ensure that the expressway reaches safety, high speed, comfort, and large traffic volume. In the early stage, due to highway segmentation investment and segmentation construction, the highway monitoring system was basically designed as a single monitoring network with a single road segment. Generally, the optical terminal + video matrix monitoring mode was adopted. However, due to the inability of resources to be shared, in the process of centralized charging, centralized monitoring, and centralized management, some devices that cannot meet the requirements are facing a phase-out situation.
At the same time, in some long road sections and the need to transmit images to the provincial center in various road sections, the optical transceiver has been unable to meet the needs of many current highway monitoring systems due to limited transmission distance and excessive use of optical fibers. With the development of social economy, people urgently need an intelligent automatic monitoring system that can provide services for highway transportation production. In recent years, the highway special communication and monitoring technology has been continuously updated, which is a comprehensive analysis of highway sections across the country. Automatic automatic monitoring is possible.
Security card, HD and smart check
The city security card is the first line of defense for urban security. It is an important measure to strengthen public security, prevent and combat current illegal crimes such as car-related and road-related. Comprehensively strengthening the standardization of urban security cardholders will have a positive and far-reaching impact on strengthening urban public security, preventing and reducing cases. There is a main line for the future development of the security card slot: the first is how to improve the user's public security management and traffic management level through the bayonet system, and collect more useful information.
This is mainly reflected in the development of the bayonet system from black and white to color, resolution from standard definition to high definition, capture range from motor vehicle to driver and pedestrian, number recognition from fuzzy recognition to precise identification, management software functions from Simple monitoring of queries to intelligent data mining. On the other hand, how to achieve energy saving and environmental protection, reduce the impact on drivers and optimize the driver's experience. Mainly reflected in the reasonable engineering design, the effect of the fill light on the driver is getting smaller, and the HD card slot blanking the privacy.
From the perspective of the application and technology development trend of the security card slot, it is concentrated in the intelligentization and high definition of the bayonet monitoring. The high-end card port has become the mainstream of the market. At present, the biggest change in the security card industry in China is clearly marked with high-definition characters in the bidding documents of the security card monitoring system in major cities. From the traditional analog imaging bayonet to the current high-definition bayonet, the security bayonet has changed in every respect.
Driving high-definition, function upgrades, electronic police to make traffic violations
In recent years, electronic police have achieved very good results in many cities. Today, the national electronic police market has a “1+3+3” pattern. East China has a market share of 50% of projects and is far ahead of other regions. The proportion of projects in South China, Central China and Southwest China is about 10-15%; the proportion of projects in North China, Northeast China and Northwest China is about 5% or less, and market investment is relatively small. The electronic police is also a system that is currently used by the traffic management department. This type of system is different from traditional security video surveillance, mainly using a camera or camera, and the trigger controller is combined with a video recognition system. When the driver has violations such as speeding, red light, retrograde, etc., the electronic police can capture the illegal image of the vehicle and transmit it to the traffic monitoring center to provide law enforcement basis for the traffic police department.
Conclusion
The road traffic in the city is the most busy. How to make traffic smooth, complex and orderly, busy and not chaotic. Security monitoring has become a necessary means in the three major applications of intelligent transportation, which is an inevitable outcome of the combination of the needs of the times and the management of science and technology.
