Safeguards for Passengers Waiting on Platforms --- Platform Screen Doors and Track Intrusion Detection System
The Taipei Metro has been committed to the safety and security of its passengers from day one. To provide passengers with a safer and more comfortable waiting environment, we began to install Platform Screen Doors (PSD) in 1995, and expect all stations to be fitted with PSDs by 2018.
There are 117 stations across the Taipei Metro system, of which 59 stations were built with integrated PSD. We are responsible for the PSD installation at the remaining 58 stations. In total, there are currently 98 stations with PSD, which represents a ratio of 83.76%. Works at another 19 stations without PSD, such as Beitou, Taipower Building, Kunyang, Jingmei, Yongning, Guandu, Mingde, Zhuwei, Xindian, Xiaonanmen and Wanlong stations are expected to be completed in 2017, using non-service hours for the installation work and tests. Hongshulin, Qiyan, Qilian, Xinbeitou, Fuxinggang, Zhongyi, Tucheng and Xiaobitan stations are expected to be completed in 2018, at which point all Taipei Metro stations will be fitted with PSDs.
MRT stations which do not yet have PSD installed are already equipped with a Track Intrusion Detection System. This system was developed in-house by TRTC and is the first of its kind in the world. By using infrared detectors and Laser Measurement Sensors, it is able to detect movement on the tracks along the platforms, around platform end doors, at the gap between the trains and platform end doors, and beyond the clearing line on the platform. It alerts the control center when a passenger moves beyond the designated area on the platform, upon which the surveillance system will lock onto the area and station staff will attend to the scene immediately. In the track area, a traffic light at 150m from the platform end door will turn red, warning drivers to slow down and be alert of the situation.
