Aiming at the problems existing in the practice, location and operation of Metro-based Underground Logistics System (M-ULS), the research ideas and improvement measures for the existing problems of M-ULS are proposed. Firstly, it summarises the shortcomings of domestic and foreign construction feasibility and practice research, and puts forward the medium- and long-term feasibility planning for the development of M-ULS; secondly, it analyses the differences between the siting of key nodes of M-ULS and the reality, and points out the ideas for subsequent research; finally, it summarises the factors affecting the overall operation of M-ULS and the influencing factors that have not yet been studied in depth, and points out several key technologies for realising the informatisation of the operation of M-ULS. and points out several key technologies to realise the informatisation of M-ULS operation. The results of the study show that China has a realistic foundation for the construction of M-ULS, but it needs to formulate appropriate cargo transport standards, establish a perfect evaluation system and improve the technologies required for information-based operation.
