Abstract: Due to the engineering conditions and special operation requirements of Pudong International Airport MRT (mass rapid transit) Line, the functions of standard platform screen door control system cannot meet the operation and organization needs of the MRT Line. Through analyzing the specific operation and organization needs of MRT Line, this problem is studied from the perspective of solutions, design and implementation plans, functional configurations and more. As a result, the final scheme is to add “mix-flow control” and “back-flow” functions to the standard platform screen door control system. Since the opening of Pudong International Airport MRT Line, the platform screen door control system has been performing safely and reliably with reasonable passenger guidance.
