Automation of the rail—removing the human factor?

The dominant safety measure is installation of platform screen doors (detection systems) preventing persons and objects from falling on the track. Currently, near 80% of stations in fully automated metro lines in operation in the world are equipped with such doors (UITP 2016).

Platform screen doors system (PSD system), as a necessary facility of modern metro engineering, are installed at the edge of the platform to isolate the track from the waiting area of the platform. They are mainly used to protect the safety of passengers and prevent passengers from falling down the platform accidentally. PSD is not only an important equipment to ensure the safety of passengers’ lives, but also an important safety factor of rail transit driving safety. The traditional maintenance method of PSD is generally based on a certain period of inspection, a certain period of overhaul and a certain period of transformation, which largely depends on the previous operation experience and the manual statistical summary of the actual fault situation. This kind of intelligent operation and maintenance mode is easy to lead to frequent equipment maintenance, and even prematurely update the equipment because of the safety of metro operation, which does not achieve the effect of full utilisation and reduce the use efficiency of PSD. On the other hand, it may also be due to the delay in the maintenance of PSD, which will not only affect the normal operation of the subway, but also cause certain social impact.
