According to the statistics of the traffic control bureau of the Ministry of public security, by the end of 2016, there were 290 million vehicles in China, including 194 million vehicles; The number of motor vehicle drivers is 360 million, among which more than 310 million are motor vehicle drivers. The huge number of motor vehicle ownership brings huge pressure to the domestic traffic, leading to various traffic problems and traffic accidents, such as traffic congestion, road accidents and urban air pollution, which have seriously hindered the development of the city. And there is a trend of gradual diffusion from the first tier cities to the second and third tier cities, which is more and more serious. There are three main reasons: first, the rapid growth of the number of vehicles exceeds the carrying capacity of the road; second, the failure to establish a perfect traffic control mechanism (flow collection, self-adaptive traffic lights, traffic guidance); third, various traffic jams caused by the lax handling of traffic violations (illegal parking, not driving according to the prescribed lane, etc.).
Development status of Intelligent Transportation
In recent years, the pace of smart city construction in China has been accelerating, and the pilot work of smart city is in full swing in hundreds of places across the country. According to the guiding opinions on promoting the healthy development of smart cities drafted and submitted to the State Council by eight ministries and commissions including the national development and Reform Commission and the Ministry of transport, intelligent transportation is listed as one of the top ten smart project construction fields.
With more and more cities begin to build smart city and intelligent transportation, at present, intelligent transportation information system has completed the laying of data collection equipment in major cities of our country, and has been widely used. According to the statistics and prediction of relevant organizations, the investment of urban road intelligent transportation system in 2016 is 35.6 billion yuan. Local governments pay more and more attention to the construction of intelligent transportation system. The intelligent transportation management of some cities has reached a high level. The urban road traffic control system, off-site law enforcement system, traffic signal system, traffic flow collection system, traffic guidance system, etc charging system and parking lot resource guidance system have all completed the scale construction. The service based on intelligent transportation system, such as road information release, parking guidance, and road condition information push, has been basically realized.
Development trend of Intelligent Transportation
With the development of new generation of information technology and the promotion of Internet plus, the new generation intelligent transportation system will include intelligent infrastructures such as sensors, communication systems and peripheral facilities, intelligent transportation vehicles such as driverless vehicles, and innovative services such as sharing automobiles, etc., which will satisfy the multi-level travel service system, intelligent logistics system and management system. Transportation will present completely different characteristics and provide diversified services. The future development of intelligent transportation presents the following major trends:
Comprehensive perception of transport infrastructure
With the development of Internet of vehicles and Internet of things technology, people, vehicles and things on the road will be fully perceived, including the real-time operation status of the road, road traffic flow data, operation status of field equipment, various traffic violations, monitoring and control of the status of traffic facilities, etc. These information provide basic support for various traffic applications and information services.
Integrated traffic control of collaborative operation
For the real-time traffic control requirements, it integrates various traffic management business systems, such as image video, bayonet electric alarm, signal control, traffic detection, traffic guidance, etc., providing integrated management hands for traffic police situation disposal, service special service management, key vehicle control, traffic violation disposal, etc. The intelligent transportation algorithm and traffic police command and dispatching business are deeply integrated to provide decision support for traffic congestion early warning and evacuation, dynamic command and dispatching, traffic organization optimization and traffic information service, as well as technical support for effective command and control under normal and emergency conditions of urban traffic.
Safe and intelligent driverless system
With the continuous improvement of intelligent technology and Internet technology, driverless vehicle is the direction of future transportation. This intelligent vehicle will integrate the detection, identification, judgment, decision-making, optimization, optimization, implementation, feedback and correction functions, and constantly learn, summarize and improve skills. In the future, we just need to move our mouth, lie in the car and wake up to our destination.
"
Open and shared traffic intelligent service
Due to the application of mobile Internet, there are many innovative intelligent transportation services, such as online car hailing, bike sharing, customized public transportation, which greatly facilitates people's travel. In the future, when the driverless technology is mature, people can more easily obtain travel services, and directly use the way of leasing to achieve travel, or rent cars to increase the capacity of public transportation to travel 。 Self owned cars will not be the most convenient and economical way to travel, which can greatly reduce the congestion of the road, and the parking problem can also be greatly alleviated.
Scientific and intelligent big data decision system
Vehicle behavior analysis
By using big data to analyze the passing data, we can quickly judge the driver's dangerous behaviors such as not wearing the seat belt and calling the mobile phone. Using different behavior analysis models, we can quickly analyze vehicle behavior, such as: foothold analysis, nocturnal analysis, peer vehicle analysis, deck vehicle analysis, regional collision analysis, vehicle trajectory analysis, first entry analysis, hidden vehicle analysis.
Urban traffic analysis
Large data system is used to clean and mine all kinds of traffic data, so as to realize the comprehensive application, deep application and advanced application of massive data.
