Feasibility Study on Retrofitting Platform
Screen Doors of Taipei MRT Stations
Yi-Ru Chen Wing-Kwong Law
Abstract
Taipei MRT stations have suffered from accidental trespassing onto the tracks over the years,
leading to a severe impact on operations and society. Both the positive and negative arguments on
retrofitting platform screen doors (PSDs) to operational stations have been raised. This study
analyzes the trend of establishing PSDs on the subway in several countries, and estimates the
feasibility of a retrofit project of PSDs on Taipei MRT stations. The main benefits include: saving
the energy exhaustion from stations, promoting the efficiency of smoke extraction, strengthening
passenger safety, and enhancing the comfort of the station environment. The downside is the
expenditure of construction. Finally, this study proposes alternatives other than just achieving
security. Although it should be taken into consideration on the cost-effective benefits of the
retrofitting of PSDs, to maintain the MRT operative safety and providing a humane environment for
both passengers and MRT staff is much more important than pursuing the economic profits. Those
above are also Taipei MRT managers’ responsibility. In conclusion, this study supports the plan of
the retrofitting PSDs in the Taipei MRT stations currently in operation.
