In April 2020, the National Development and Reform Commission defined the scope of “new infrastructure”, and intelligent transportation infrastructure was included in the category of convergence infrastructure as one of the key areas of emerging technologies that integrate and innovate traditional infrastructure. Intelligent transportation infrastructure requires comprehensive sensing of road, vehicle, human, environment and other related location data (to achieve “human-vehicle-road” comprehensive interconnection), full spatial and temporal traffic control for each road, and full traffic control for each vehicle, in order to have ubiquitous and seamless travel service capability.
The core of the construction of intelligent transportation infrastructure lies in the intelligent and precise control of connected cars and intelligent networked vehicles, and the intelligent and precise control of connected cars is an information-physical system (CPS) network with precise spatio-temporal location services, and the precise control of remote spatio-temporal location is its necessary requirement.
At present, the trend of integration of “Internet +” intelligent transportation and many industry fields tends to be clear, mainly in the following aspects.
Technology integration. Combined with new economic and social development needs and technological innovation trends, especially in the context of the smart era, highlight the integration of new technologies, such as the integration of heaven and earth networks, narrowband Internet of Things, Beidou satellite navigation and its augmentation system, a new generation of mobile communications, AI, intelligent manufacturing, new materials, new energy and other applications in the field of intelligent transportation [3].
Data integration. Relying on the “Internet +” technology to build a cloud platform of traffic data, the public collection of travel data (such as road conditions, parking, traffic flow, public transportation, etc.), public traffic management departments to provide traffic control, congestion, police, accidents and other data convergence and automatic map presentation, to provide a scientific basis for eliminating congestion It also provides a solution of “crowdsourcing update” to solve the problem of timeliness of high-precision maps required for autonomous driving.
Field integration. The transportation change with the “four” automobiles as an important feature is emerging, and the integration of automobile manufacturing, automobile service industry, energy network, traffic operation service, mobile Internet, information service, intelligent transportation and other industry fields will be the trend in the future.
Infrastructure integration. 2019 “Outline of the construction of a strong transportation country” clearly puts forward the development goal of intelligent networked vehicle research and development, and thus the formation of an independent and controlled, relatively complete industrial chain. The ubiquitous and controllable transportation information infrastructure represented by Beidou satellite navigation and 5G will support the integration and innovation of intelligent transportation suitable for national conditions.
Travel service mode integration. The “Internet +” intelligent transportation for the traveling public “access” that is iTaaS, has been clearly included in the “construction of a strong transportation country outline”. The integration of transportation services will provide the key foundation and core support for the service innovation and upgrade of new industry and new mode.
“Internet +” intelligent transportation system architecture.
The “Internet +” intelligent transportation technology system, in essence, is an ecological system that integrates “cloud, network, end” and other network support technologies. The “end”, including various intelligent vehicle control terminals, intelligent vehicle safety and security terminals, road health perception equipment, road condition perception equipment, road climate perception equipment, etc., constitute the “Internet +” intelligent transportation perception / access / communication technology system. system. The “network”, which provides the channel for information transmission, involves the new generation wireless communication network represented by 5G, the indoor and outdoor integrated, seamless, high real-time, highly reliable and high-precision location service network represented by BeiDou satellite navigation, and the intelligent vehicle network represented by net-connected vehicles. “Cloud”, including a new generation of road network information infrastructure, intelligent analysis platform of traffic big data, and commercialization platform of traffic industry information resources, for highway, railroad, waterway, aviation and other traffic resources information, using the integrated form of Internet platform to provide traffic sharing resources in an integrated manner.
From the perspective of the platform structure, the construction of “Internet +” intelligent transportation technology system, but also need to face the industrial Internet and consumer Internet “application layer – intelligent control layer – physical implementation layer ” system framework. On the whole, we should strengthen the support of new transportation infrastructure such as intelligent transportation information system, management system, public transportation system, intelligent vehicle control system and emergency rescue system, and implement the standardization and systematization of key technologies such as multi-source cooperative sensing, indoor and outdoor combined navigation and positioning, multi-source data fusion, human-machine interaction, intelligent computing platform and high-precision map. Specifically, combining the macro demand of “Smart+” and the trend of technology integration, we focus on the edge computing capability of the “end” in terms of computing power, add an edge processing platform layer, take intelligent vehicles as the main carrier of the edge computing layer, and focus on breaking through the new generation of AI In the new intelligent system cloud service platform layer, focus on the collaborative intelligent service application of new technologies in the field of intelligent transportation, control in the form of “traffic brain”, and provide intelligent security for the transportation system, focusing on breakthroughs in AI engine, system simulation and human-computer interaction. In the new intelligent system cloud service application layer, the iTaaS concept is highlighted, with the focus on the new mode of shared transportation services, research and breakthrough in intelligent transportation platform technology, and reshape the industrial ecology through technological innovation.
In addition, in order to adapt to and lead the new economic normal and break through the inertia of the traditional model to respond to new production methods, new business models and new strategic needs, we should create a relaxed and orderly development environment, accelerate the technical exploration and application demonstration of intelligent transportation, and promote the disruptive transformation of transportation sharing travel methods. By improving the service level to adapt to the diversified transport needs, and by ensuring investment to serve the “stable growth”.
Suggestions for countermeasures.
