Line 10 has significantly improved system safety, reliability and operation efficiency, etc., compared with the original GoA2 projects. This has shown that the GoA4 meets the need of large passenger flow in China′s urban rail transit, and plays a good demonstration in this field. On May 17, 2019, China Urban Rail Transit Association held the "Shanghai Rail Transit Line 10 with UTO System On-site Meeting", which brought together representatives from almost every Chinese subway construction and operation enterprise sent to attend. During the meeting, the association suggested that the UTO requirement path and technology be planned and developed scientifically in line with local conditions. According to the latest World Report on Metro Automation from UITP (International Association of Public Transport), the length of UTO lines is expected to grow from 1,026 km (y2018) to 4,007 km (y2030), with the overwhelming majority coming from China.

Although GoA4 UTO system has about 30 years of history, how to utilize the rapid development of information, communication and other modern elementary technology to address the demand of urban rail operation in China remains a new topic in this industry. Therefore it is necessary to actively promote all-around research of the next-gen transport management, train control, passenger service and equipment operation & maintenance in terms of the "Smart Rail Transit", to initiate domestic and international technology exchanges and cooperation sharing, to accelerate the industrialized demonstration and promotion of scientific research outcomes, and to help improve the Smart Rail Transit ecosystem.

As a major R&D system innovation, Shanghai Engineering Research Center of Driverless Train Control of Urban Guided Transport (hereinafter referred to as the Center)was established in May 2017 with the approval of Shanghai Science and Technology Commission, assuming the important responsibility and historical mission of technological innovation and engineering application of new generation automatic train control system in rail transit field. Based on CASCO Signal Co., Ltd., the Center is jointly established by Shanghai Shentong Metro Group, Tongji University, East China Normal University, Shanghai University etc. It deeply integrates "Industry, University, Research and Application" into a scientific research platform converging many renowned experts in the industry, fully consolidating the advantages of all parties and forming industrial synergy.

The Center construction has been completed in two years and the first domestic professional integrated laboratory servicing all UTO technology has been put into use. The laboratory pioneers a way for UTO scenario validation by a combination of real system and virtual scenario, realizing the full professional UTO integration on laboratory level. Moreover, the Center acts as an open research platform for next-gen automatic smart urban rail transit solution.

The Center studies UTO requirement norms, project design norms and safety norms under normal, failure and degradation scenarios, meantime designs automatic interaction modes between subsystems and optimizes operation panel with man-machine engineering. At present, the Center has the ability to support the complete train control system integration of GoA4 fully own-developed CBTC (TRANAVI) and localized CBTC (U888), as well as . It also able to support the intelligent system integration of operation, management and maintenance of an integrated urban rail transit. The standard open platform of this system is compatible with the third-party application software and modules integration, and give access to subsystems to enable the information integration and interaction between different urban rail production systems.

With the mainstream of the UTO line construction in China, The Center has already undertaken UTO projects of Chengdu Line 9, Shanghai Line 15 and Line 18, as well as Beijing Line 3. Especially on Chengdu Line 9, it acts as the coordinator of system integration. We are glad to see that the synergies between technology and system innovation on UTO are yielding particular progress in Shanghai. Let us continue our effort to contribute more to the smart metro undertaking in China.
