Analysis on the development of intelligent transportation

 

The world is undergoing unprecedented changes in a century. Science and technology have promoted the development and progress of various fields. The emergence of cutting-edge technologies is making profound changes in the field of transportation. With the vigorous development of cloud computing, big data, artificial intelligence, mobile Internet technology and other high-tech, intelligent transportation has jumped onto a new fast lane of development. This paper starts with the basic concept of intelligent transportation, introduces the development process of intelligent transportation in China, reveals the significance of intelligent transportation, analyzes the development trend of intelligent transportation, and puts forward some thoughts on the development of intelligent transportation.

 

Basic Concept of Intelligent Transportation and Its Development in China

 

Intelligent Transportation System (ITS) refers to building a safe, fast, efficient and green transportation system by integrating existing transportation facilities and vehicles through modern information, communication, control and other technologies. Intelligent transportation originates from transportation informatization and transportation engineering. China has attached importance to intelligent transportation since the 1990s. In 1995, China first appeared at the World Intelligent Transportation Conference. After that, China has successively participated in the relevant conferences of ITS, thus recognizing the development trend and necessity of ITS. Since China attended the EU China ITS seminar in 1997, ITS has gradually moved to the stage of high-tech industry development. In 2000, China's ITS system and strategic framework were formally proposed. After 2001, the national "Tenth Five Year Plan" proposed a major scientific and technological project of "core technology development and demonstration project of intelligent transportation system", and ITS entered the development stage. Since the 12th Five Year Plan, the country has invested hundreds of billions in intelligent transportation construction, and a series of policies have been gradually introduced to improve the top-level design system of intelligent transportation.

 

Significance of developing intelligent transportation

 

It is our historical responsibility to develop intelligent transportation. With the development of the times, the comprehensive transportation system represented by new energy vehicles, ocean going ships, high-speed trains, and large airplanes has been initially built. The management system represented by intelligent transportation is in the ascendant. The comprehensive transportation system represented by highways, high-speed railways, oceans, and aviation in China is developing rapidly. Under the background of the deep integration of new technology system dominated by information and Internet and transportation technology, intelligent transportation system has higher security level, higher operation efficiency and higher service level than traditional transportation system. The development of intelligent transportation is a major national strategy.

 

Development trend of intelligent transportation

 

Although the support of policies and the progress of science and technology in recent years have brought dividends to the development of intelligent transportation, the development of intelligent transportation in China is still in the primary stage, and the basic conditions are still weak. In the future, the development of intelligent transportation should further strengthen the transportation big data mining and intelligent transportation information services, carry out in-depth research on the technology of driverless vehicles, plan ahead the vehicle road collaborative intelligent system and Internet of Vehicles, comprehensively promote intelligent transportation information perception and services, and improve the innovation ability of key technologies of intelligent transportation.

 

First of all, strengthening transportation big data mining and intelligent transportation information service is the focus of intelligent transportation development. Vehicle road coordination is a cutting-edge technology in the field of intelligent transportation in recent years. China should deploy it as soon as possible to occupy the strategic commanding heights of intelligent transportation. China has been short of core technologies in terms of traffic signal control and traffic simulation technology. We should step up the organization of scientific and technological research, combine the characteristics of China's actual traffic, innovate and improve, make essential breakthroughs, and get rid of the long-term dependence on imports.

 

Secondly, it is a difficult point for the development of intelligent transportation to carry out in-depth research on the technology of driverless vehicles. The future development direction of unmanned driving technology can be divided into highway environment, urban environment and unmanned driving system under special environment. In the expressway environment, the use environment is defined as a structured expressway with good signs, which mainly completes the functions of road sign line tracking and vehicle identification; Unmanned automatic driving in urban environment will become the focus of research in the next stage. In urban environment, unmanned driving is slower, safer and more reliable, and has better application prospects, but the urban environment is more complex, which puts forward higher requirements for perception and control algorithms; In special environments, applications in military and other special conditions have different emphasis on performance requirements, such as vehicle reliability and adaptability to harsh environments.

 

Third, planning the vehicle road collaborative intelligent system and the Internet of Vehicles in advance is the key to the development of intelligent transportation. The large-scale development of the Internet of Vehicles industry requires the formulation of Internet of Vehicles standards and construction related specifications. Under the background of big data era, vehicles are a small branch of Internet of Vehicles. In order to open up your own new blue sea and successfully break through the encirclement, you need to establish your own data barriers. One direction is to develop hardware with Chinese characteristics, use the combination of software and hardware, and use Internet thinking to operate and promote, and finally establish a huge and complete building data system; The other direction is to get through the data construction of the industry and establish cross industry databases.

 

Fourth, the comprehensive promotion of intelligent transportation information perception and service is the trend of intelligent transportation development. The key tasks of intelligent perception and service of traffic information mainly include ETC system and traffic flow information collection, which will further promote the development of intelligent transportation industry. ETC system is based on on-board electronic tag to realize short distance communication with microwave antenna. It does not need to stop the vehicle to swipe the card and pay cash to the toll collector, and automatically reads the process of completing the charge processing. ETC system has convenient features such as no parking, no watchman, no cash, etc. Traffic flow information collection uses the traffic information collection system installed on roads and vehicles to collect, process and release dynamic information such as traffic flow, driving speed, control information, road conditions, parking conditions, parking lots, weather, etc., which becomes an important part of the intelligent transportation system.

 

Finally, improving the innovation ability of key technologies of intelligent transportation is the core of intelligent transportation development. To improve the innovation capability of key technologies of intelligent transportation in China, it is necessary to combine existing technologies and foundations, and introduce technologies and applications such as Internet of Things, cloud computing, data mining, etc. in the field of intelligent transportation to develop a new generation of intelligent transportation systems.

 

Thoughts on the Development of Intelligent Transportation

 

If we learn from the development experience of intelligent transportation in developed countries, we find that they have improved the coverage of intelligent transportation systems and vehicle mounted systems in about ten years, and then explored and developed the integrated system of the Internet of Vehicles, which will be further industrialized and scaled in the future, and become the most important application to promote the development of the Internet of Animals industry. In this process, the starting point of the intelligent transportation system is to serve the safety and efficiency of travelers, which is different from the main government services in China. This may be mainly because the transport infrastructure in developed countries is at a higher level through long-term urban planning and construction, and the quality of travelers and drivers has also solidified to a higher level in a long time. Therefore, the development of intelligent transportation in developed countries can serve travelers from the perspective of safety and efficiency, while the urbanization process and motor vehicle development in China are too fast, Far beyond the capacity of the city and the quality of urban travelers, the disregard of traffic laws and regulations has further caused problems of congestion and safety. Therefore, for the governments at all levels in China, the traffic order can be quickly established by means of high-pressure management and detection, with different emphasis and different service objects at home and abroad; However, from a more long-term perspective, serving travelers will become an inevitable trend for the further development of China's intelligent transportation. Intelligent vehicle system, intelligent road test system and intelligent traveler system will become the further development direction of intelligent transportation industry. With the further enhancement of traffic complexity, efficiency improvement will also encounter bottlenecks, which will definitely put forward higher requirements for the ability of managers and travelers.

 

Intelligent transportation integrates "people, vehicles and roads" in the transportation system. It can provide the public with timely traffic information such as road conditions, transfer, parking, positioning and weather, effectively solve urban road congestion and travel safety problems, improve urban carrying capacity and operating efficiency, and reduce carbon emissions. In recent years, the successive introduction of policy documents and the continuous updating of new technologies have led to the accelerated development of intelligent transportation. Intelligent transportation will further enter the public view. Its continuous innovation and rapid development are providing strong support for the intelligent transportation infrastructure, the green transportation development model and the cross-border integration of the transportation industry ecosystem, and injecting inexhaustible power into the high-quality economic and social development.
