In Revised: 15-03-2020 this paper, the importance of smart metro development is discussed from Accepted: 20-03-2020 the perspectives of national development background, technology development trends, and people’s basic requirements, and the features of KEYWORDS smart metro in multiple levels are analyzed. On this basis, the construction Urban rail transit target, system architecture, and construction methods of smart metro are put Smart metro forward, and the applications of smart metro are elaborated from smart Technical framework construction, smart operation and maintenance, and smart service. Smart application With the rapid development of new generation 1. Development background communication and computer technologies such as 5G, block chain, and artificial intelligence, mankind 1.1. Construction of transportation power has ushered in the fifth industrial revolution, which has also added wings to the development of smart In September 2019, the Central Committee of the metro. In recent years, the smart applications of Communist Party of China and the State Council urban rail transit in China have been in the process issued the notice of “Outline for the construction of of continuous exploration and innovation. The a powerful transportation country”, requesting to applications such as barcode scanning, face further emancipate the mind, forge ahead, promote recognition, and internet ticketing have brought the transportation development from the pursuit of passengers a new ride experience while improving speed and scale to a greater emphasis on quality and the quality and efficiency of operation management efficiency and from relying on traditional factors to and maintenance management. paying more attention to innovation driven transformation, build a safe, convenient, efficient, Shanghai Metro actively promotes the construction green, and economical modern comprehensive of “Smart Metro” in the transformation and transportation system, create first-class facilities, development, and actively adapts to new first-class technology, first-class management, and development trends such as the scale of urban rail first-class service, and build a powerful transit engineering construction, diversified transportation country with satisfactory people, financing methods, networked line layout, strong security, and world leading. diversified transportation systems, intelligent operation methods, and support technology Innovation is the first driving force for development informatization, realizes resource integration, model and the strategic support for building a modern innovation, and efficiency optimization, so that the economic system. The state requires that we aim at service level can be further improved and the rapid the frontiers of world science and technology, development of Shanghai’s urban rail transit can be strengthening basic research, and achieving major boosted. breakthroughs in forward-looking basic research 1 Chunjie et al. (2020) New Metro (2020) 1(1): 1-10 and leading original achievements. Therefore, construction, it is the main starting point for high- strengthening applied basic research, expanding the quality development of urban rail transit and a vital implementation of major national science and way for independent innovation and development of technology projects, and highlighting the the rail transit industry. Rail transit plays an innovations of key common technologies, frontier increasingly important role in urban transportation. leading technologies, modern engineering The degree of intelligence and service will directly technologies, and disruptive technology can provide affect the ability of smart transportation. Therefore, strong supports for building a strong country with the construction and innovation of smart subways advanced science and technology, high quality, should be vigorously promoted from the perspective foremost aerospace, vigorous network, powerful of supporting smart cities and smart transportation. transportation, great digital power, and smart society. 1.3. Operation status of Shanghai Metro Therefore, the implementation of technological Shanghai has the largest urban rail transit network in innovation is a major strategy for the next stage China. As shown in figure 1, by the end of 2019, the development of China. As the core force of total length of Shanghai urban rail transit network transportation in large cities, in order to cooperate operation lines had reached 705 km (including 29 with the vigorous promotion and support of km of maglev), the number of stations had increased technological innovation at the national level, rail to 415, and the number of transfer stations had transit can bring new development through increased to 57. In 2019, the scale of Shanghai’s intelligent and smart innovative applications. urban rail transit line network ranked first in the world at 801.3 km, there were 3.88 billion 1.2. Support smart city construction passengers throughout the year, and the number ranked third in the world. Smart city is the new trend of urban development under “Internet+”. Smart transportation is an With the continuous expansion and extension of the important component of a smart city. It can improve urban rail transit network, the pressure of passenger the efficiency of resource utilization while greatly flow has gradually increased. The proportion of improving the transportation efficiency, ensuring public transport trips in Shanghai’s urban rail transit the traffic safety, and improving the transportation has continued to increase from 5% in 2000 to more environment. The outline of the national medium- than 66.6% at the end of 2019 (excluding taxi trips). and long-term science and technology development At present, the average daily passenger flow of plan puts forward the following requirements for Shanghai’s urban rail transit network has exceeded transportation intelligence: 10 million passengers. On March 8, 2019, the highest daily passenger flow reached 13.294 million “taking smooth and convenient humanized passengers. Rail transit has become the primary transportation services as the core, choice for Shanghai residents and tourists. strengthening overall planning, developing the information and intelligent technology In recent years, the construction and commissioning for transportation system and the of projects in succession, e.g., fully automatic transportation technology with safety and operation, code sweeping, construction management high-speed, improving the capacity and platform based on the building information model efficiency of the transportation network, (BIM), Shanghai Rail Transit Network Operation realizing the sharing of traffic information Command and Control Building, and Shanghai Rail and the effective connection of various Transit Industry Data Center, provide a new way for transportation modes, improving the Shanghai rail transit ultra-large-scale network technical level of transportation operation operation management (Yu, 2018). Shanghai urban management, and developing rail transit needs to seize the development comprehensive transportation (Gu, Huang opportunities of smart cities, develop smart metro & Hu, 2016, p. 1).” well, and maintain the industry’s first-mover advantage through quality leadership under the Smart metro construction is the guiding project of framework of smart cities and smart transportation. smart transportation construction and smart city 2 New Metro (2020) 1(1): 1-10 Chunjie et al.
