Smart transportation is becoming the main force of new infrastructure, with the structural deepening of new energy vehicles and automobiles into the intelligent manufacturing industry chain, the intelligent transportation industry structure has become the green development of China's economic development into the new normal into carbon neutrality, carbon peaking and The industrial layout of China's intelligent manufacturing represented by new infrastructure. The attempt to decarbonize the advantages brought about by the gradual optimization of the power battery technology of new energy vehicles and the participation of all-round hardware technology fist products in the intelligent production and manufacturing of automobiles have formed the initial industrial framework of China's road intelligent car manufacturing industry chain in the new era. Smart transportation can not only help the integration of new infrastructure and traditional infrastructure, but also promote the construction of smart cities and promote the upgrading of the mainland from a "transportation power" to a "transportation power".
Intelligent transportation, governance capabilities modernization, unmanned driving
The State Council issued the "14th Five-Year Plan" modern comprehensive transportation system development plan. The plan proposes to improve the coverage, real-time and reliability of information transmission in the field of transportation. Strengthen the application of smart cloud supply chain management and smart logistics big data to accurately match supply demand. Orderly build a smart management platform for urban transportation and strengthen the refined management of urban transportation. In this process, car companies, consumers, governments and other main traffic participants enter the layout of intelligent transportation in different roles, so that transportation infrastructure has the ability to perceive, realize the management mode of intelligent decision-making, improve operational efficiency, and improve service experience. Accelerate the development mode of traditional transportation towards a new type of intelligent transportation based on data and technology, mainly through four aspects of interconnection, electrification, unmanned driving, intelligent travel, etc., and gradually realize the operation scheme and application scenario design of intelligent transportation with the intelligent exploration of automobiles.
First, interconnectivity, electrification, unmanned driving, and intelligent travel constitute the development path of intelligent transportation
The current intelligent transportation industry structure is premised on the establishment and improvement of the intelligent travel system. Smart mobility refers to an efficient and sustainable passenger and freight ecosystem built by stakeholders through data and connected technologies. The system application of smart travel has been demonstrated from the ride code to urban public transportation, from automatic driving, 5G vehicle-road collaboration, traffic big data to urban traffic management, and from smart high-speed, smart port, smart aviation to intercity traffic operation.
The interconnectivity of smart transportation. With the increasing diversification of digital services and the emergence of on-demand functions, the automotive operating system has become the focus of the layout of new models, and smart transportation has realized the interconnection of human-computer interaction of automotive hardware devices and software ports, and perfectly integrated vehicles, roads, clouds, and networks to build intelligent transportation lifeforms. From the perspective of interconnection, modern car companies have improved human-machine technology after a long period of practice, alleviated the pressure on chips, and made many attempts in the content and user experience of interconnection services.
First of all, the underlying port design is carried out from the automotive system/electrical architecture to improve the operational portability of the electrical architecture. Second, the combination of network infrastructure is the key to achieving human-computer interaction. Embedding some useful and entertaining content from a consumer perspective has become a key element in improving the intelligent experience of current driving platforms. For example, the synchronization of the hardware configuration of the central control large screen realizes the exploration of consumption scenarios for car navigation and video and audio entertainment. Third, from the perspective of the rejuvenation of automobile carriers, we should consider the market share of young people. Through the proportion of "digital consumers" in the population, the consumer goods of automobile enterprises are modernized, so that they can adapt to the consumption habits of young people and occupy the future market. Fourth, free basic services constitute the customer service system of the intelligent transportation system. At present, many e-commerce platforms entrust so-called artificial intelligence systems to achieve their own customer service hosting, but in fact, they reduce the user experience. Through the online or online human-computer interaction of the car company platform and the warm feedback of real people, the interconnection mechanism can be changed and better matched with intelligent traffic management. Finally, smart transportation is not very perfect from the perspective of regulations. Smart transportation needs to rely on the interconnection function to become the mandatory standard of time and scope of application, so there must be a data sharing and privacy regulations to define the scope of the appeal. Subsequent relevant regulatory agencies need to carry out legal system design for data collection and user privacy in smart transportation.
Electrification of smart transportation. The electric trend of intelligent transportation is rooted in the fact that with the anxiety of modern society about the limitation of fossil energy and carbon emissions, the exploration of the power mechanism covered by the travel scenario of practicing clean energy is locked in the development of electric vehicle technology of various electric power energy and the innovation related to battery energy storage has become the mainstream society.
From the perspective of electrification of vehicle drive energy. First of all, in terms of power technology, battery and power system performance have become the main factors restricting the development of electric vehicles. Whether it is lead-zinc batteries, lithium carbonate batteries, nickel-cobalt-manganese batteries or hydrogen energy hydrolysis batteries, they are all different exploration directions of the power mechanism on the battery. More perspectives on energy supply are mainly in the development of core technologies in terms of miniaturization of power support and maximization of energy storage efficiency. In terms of power supplytrain, relying on the current mechanical design reform and engine design concept innovation, the realization of electric power and engine powertrain is still a major difficulty that needs to be overcome at present. Second, the popularity of vehicle electrification faces two-way restrictions on the manufacturability and capacity of electric vehicles. The production parts of electric vehicles are relatively diverse, even if Tesla has open sourced the relevant power technology and charging pile technology, the systematization of the production link and the modularization of the power system still need a long period of integration, and it is impossible to achieve a faster large-scale industrial production, and the lack of production capacity under the established conditions of insufficient market supply and manual assembly leads to insufficient market coverage, and then cannot form a scale effect to reduce procurement costs. Third, the charging infrastructure is not perfect. In the experience of using electric vehicles, users are most concerned about the power endurance. If the hardware of the charging pile cannot be realized, it is difficult to form a chain traffic scene, and the driving range of electric vehicles will be restricted, turning into a "old man's music" grocery shopping car. Fourth, the consumer perspective has not formed a high-end cognition of electric vehicles. Although BMW, Mercedes-Benz, Maserati and other car companies have successively launched electric high-end cars, relying on the original car chassis for vehicle power system replacement, but the size of the "rational green" consumer group has not grown on a large scale, even if the economy is in some levels, the total cost of pure electric vehicle ownership is lower than that of fuel vehicles. Fifth, from the perspective of regulations and incentive mechanisms. The promotion of electric vehicles is conducive to the government to achieve the target emission level, based on the need for carbon neutrality and negotiation to achieve the standard of different cities to promote pure electric / plug hybrid incentives, Beijing, Shanghai and other cities also have fuel vehicle related ban restrictions, and improve the construction of charging piles with the help of additional income / cost savings brought by V2G / V2X charging to promote the market coverage of electric vehicles.
Intelligent transportation driverless and smart travel exploration. The preference for private transport has hindered the growth of smart mobility, but cities are encouraging pilots of new modes of transport and developing their own designs for driverless and smart mobility in the public domain.
From the perspective of the exploration of driverless cars for smart transportation. First, the technical aspect requires ADAS capabilities in proportion to users and enhanced data processing capabilities in end equipment vendors. Secondly, from the driver interaction, it is necessary to match the network and traffic infrastructure to achieve the positioning of the terminal that coincides with the driver's real coordinates, and intelligently judge the road conditions for alternative road support. Third, the driverless experience from the perspective of consumers, the L4 passenger transport system and the robot taxi have fully entered the pilot stage. Tesla and other high-speed cruise and follow-up mode is also a new breakthrough in unmanned driving technology. In the field of autonomous driving and vehicle-to-road collaboration, Tencent's 5G vehicle-to-road collaboration platform, traffic cloud control platform and V2X data service engine built based on edge computing open up the digital closed loop of people, vehicles, roads and clouds. At present, the Vehicle-Road Collaboration Scenario Verification of 5G Edge Computing has been done in beijing Shougang Winter Olympic Park. At the same time, we will cooperate in the field of automatic driving, use virtual simulation technology to accelerate the development of intelligent and connected vehicle simulation experimental projects in Changsha, and help build the national intelligent networked vehicle (Changsha) test area.
From the intelligent transportation intelligent travel practice to analyze. First of all, the popularization of smart terminals in technology. The penetration rate of smart phones and the matching of GPS, reversing radar and other terminal equipment of the loading terminal of the car make the overall intelligence of the car improve, and the comprehensive use of data judgment to form vehicle navigation and automatic reversing into the warehouse has become a trend. Second, the ease of access to smart services and the number of vehicles available to the fleet are also gradually improving. Services such as free battery replacement at offline power stations of NIO electric vehicles have improved the service scenario support for insufficient power and the level of connection between travel modes from the perspective of consumers. Third, smart transportation products are flexibly priced to maximize vehicle utilization and the number of available vehicles, and the total cost of economic ownership is better than that of private cars. Travel platforms such as Didi and Dida or express car carpooling services are essentially matching travel needs through algorithms to achieve the convenience of travel for both drivers and passengers. Fourth, demand for electric vehicles has been boosted by government incentives and an increasingly abundant model selection, and the industry's flashpoint is just around the corner.
Second, automobile intelligence and new energy vehicle manufacturing industry structure reorganization
At present, the development of China's automobile intelligence has a strong driving force, and it is currently affected by three factors. The first is the increase in vehicle sales brought about by the reduction of the lack of core in the vehicle, and the second is the increase brought about by intelligence, including networking. The other is the increase brought about by the electrification of cars.
Domestic chip substitution began to discuss intelligent driving. Smart transportation requires chips plus high-precision positioning perception, which is a subdivided track, precision positioning plus inertial navigation combination navigation hardware, involving antennas, cores, modules, boards and fusion algorithms and consider intelligent driving and ADAS requirements. Driverless delivery is a scenario where autonomous driving technology is currently landing, but when a hardware is always bad, the software may also have BUGS, how to ensure safety in this case, the safety logic of intelligent driving is mainly focused on the terminal hardware. Foreign countries like Qualcomm and Guotong, and domestic ones like MediaTek and Unigroup have innate advantages or opportunities. The first is the logic of increment, the increase in demand brought about by the intelligence of the car, resulting in the gradual reduction of the price of the product, so that the original professional-level sensor can be used as an ordinary sensor application. The second is the localization of alternative logic, in fact, in recent years, domestic manufacturers in the chip module, board-related fields began to appear technological breakthroughs, and formed a product generational catch-up, with a certain domestic chip substitution logic. Relying on the high-precision location service providers of traditional surveying and mapping business, including The Nuclear Starcom under BDStar, as well as Enterprises such as Huate Navigation and Zhonghaida, have hardware technology reserves.
In addition, with the improvement of intelligent driving performance, the two-eyed driving operation in the driving experience is liberated, and more time is spent on the embodiment of car interaction. At present, from l1 to l2 to l3 driving, the future there are l4, L5, currently mainly concentrated in L2 to L3 driving or assisted driving links. Second, the entire cockpit belongs to the interaction between the car and the car has been intelligent, including software-oriented, such as operating systems, more hardware innovations that may be concerned by the electronics industry, such as a larger screen represented by Tesla, but also including a HUD head display, which is imported from the fighter IE, such as a variety of more integrated dashboards, intelligent electronic dashboards and so on. They are all carried out around the intelligent conditions and are divided into different lines. The car is equivalent to the third space, and the premise of intelligent driving is the dataization of the entire driving link. From the perspective of the sensing layer, it is basically the direction of pure optical algorithms represented by Tesla. The other is that the hybrid direction requires lidar, ultrasonic radar plus optics, which is mixed to achieve greater safety.
At present, the advantages of the optical algorithm school are clear. An algorithm that is relatively low cost and can be improved through OTA upgrades. First of all, the upgrade of software is relatively easy, and the upgrade of hardware may often require higher costs, so it is relatively difficult. And relying on higher computing power will also consume more electricity, so it has a certain degree of impact on battery life. The second way is lidar, which is more expensive, but gradually forms a scale. The cost of lidar from mechanical to solid-state has dropped from tens of thousands to thousands. These two have their own advantages, but in the long run, with the maturity of technology and the expansion of scale, the cost of hardware will be greater, so the future cost of lidar will not be as high as it is now, and the algorithm will gradually mature. Lidar is a trend of future development, and it is optimistic about the comprehensive solution of lidar millimeter wave radar, ultrasonic wave and optics for a long time.

Intelligent transportation platform design and intelligent transportation scene application
Smart transportation is a reflection of new infrastructure construction in the transportation industry. The accelerated development of new infrastructure is the necessary material foundation for the widespread popularization of new technologies and new production factors in the whole society, and the new industry of intelligent transportation is also the key support for the rapid growth of new products, new formats and new economic sectors. Unlike the automobile industry produced by assembly lines such as internal combustion locomotives, which has gradually matured after a hundred years of evolution and development, the new energy vehicle facilities of intelligent transportation and its transportation carrier have only emerged in recent years with the maturity of industries such as sensors and map tools, and their leading technologies, product forms, market demand, supporting industries, business models, etc. are in the cultivation stage and have not yet taken shape steadily.
Conceptually, smart transportation is an industrial integration based on intelligent transportation. In the field of transportation in the intelligent transportation system of future transportation, we will make full use of technologies such as the Internet of Things, Internet, cloud computing, artificial intelligence, automatic control, and mobile Internet to control and support all aspects of traffic management, transportation, public travel, and the whole process of traffic construction management, and comprehensively grasp the comprehensive monitoring and command of traffic, traffic safety management and emergency response from four specific scenarios such as innovative traffic construction, digital traffic management, urban traffic operation and traffic travel services.
