On October 29, Chen Xiangsheng, an academician of the CAE Member, Cen Yanqing, director of the Department of Science and Technology of the Ministry of Transport, Zhou Wei, former chief engineer of the Ministry of Transport, Shi Baolin, president of the Academy of Transport Sciences, Wang Changjun, director of the Road Traffic Safety Research Center of the Ministry of Public Security, Cai Yuhe, secretary of the Party Committee of the China Communications News Lin Rong, Deputy Director of China Communications Communication Information Center, Pei Minshan, Deputy General Manager of China Communications Construction Group Co., Ltd., Yao Enjian, Secretary of the Party Committee of the School of Transportation of Beijing Jiaotong University, Nie Xiaojian, Chief Scientist of Baidu Intelligent Transportation, and other authoritative experts and business people in the industry discussed and shared the above issues. Future path: where is the focus of China's digital transportation construction? Shi Baolin shared a special perspective: observing the trend of digital transportation construction during the "Fourteenth Five Year Plan" period from the three batches of 348 pilot tasks for building a transportation power that have been approved. In his opinion, it is mainly reflected in four areas: first, "perception improvement" in infrastructure. Digital survey and design, intelligent infrastructure, and intelligent maintenance and operation have been developed with ubiquitous perception as the main feature and improvement of security, efficiency, and service quality as the development direction. The second is "intelligent and efficient" in the field of transportation equipment. New transportation tools and intelligent construction equipment such as new rail transit systems and autonomous vehicle have been developed to ensure safety, reduce costs and increase efficiency. The third is "convenient connectivity" in the field of transport services. Provide convenient, economical and reliable services for passengers and cargo owners, such as MaaS, e-ticket in the whole process, etc. Fourth, "online collaboration" in the field of industry governance. The development direction is to provide online "one-stop" government services for the public through the collaboration of government, enterprise and other business systems. Lin Rong also said that around the "one brain, five networks and two systems" proposed in the "Fourteenth Five Year" Development Plan for Digital Transportation, the focus of transportation digitization should be on infrastructure and equipment, as well as digital management and services, especially in the aspect of digital development ecology. The four key areas of digital transportation are perception, transmission, technology and application. The application of "Internet plus+transportation" will fully cover and fully display the new business form of transportation through digital transportation. Data is one of the core driving forces for the development of digital transportation, and also a key element for the development of intelligent transportation. Focusing on building a comprehensive transportation "data brain", Wang Changjun put forward two suggestions: on the one hand, we should attach great importance to data quality. Data needs to be integrated and expanded to find the parameters and valuable information that meet the needs; On the other hand, the purpose of building a "data brain" is to solve practical problems in the transportation industry by building a "data brain" to gather multiple dynamic and static data. At the same time, there should be corresponding schemes, appropriate algorithms, accurate models, and systems, platforms or applications that can solve problems, so as to better create a comprehensive transportation "data brain". Yao Enjian is very concerned about the security of the "data brain". He suggested that we should strengthen the construction of "data brain" security management and build detailed security management
