Preventing subway deaths through laser sensors

Pushed on the subway track, this man is about to die, read the December 4, 2012 edition of The New York Post. The controversial cover photo of the newspaper, more than the news itself, sparked outrage from readers and Internet users. The tragedy that befell 58-year-old Ki Suk Han of Queens, New York, continues to percolate as a hate crime involving a Black and an Asian man. The latter had been crushed ‘like a rag doll’ by the train, according to a witness.

The death of Ki Suk Han is among the many subway deaths which the Metropolitan Transportation Authority (MTA) is hoping to prevent in the future by rigging subway platforms with intrusion technology. The technology uses laser sensors connected to an alarm system, flashing lights, or anything that will trigger alert in case someone steps or has fallen onto the tracks.

MTA officials are considering how the technology could be used in a more efficient yet cost-effective manner. The officials said that the laser sensors are a more viable option than platform screen doors which are complicated to install because subway trains come in different sizes, and some units have curved and tapered platforms. Regardless, MTA is open for other methods to improve security and safety in subway trains.

While the agency is yet to roll out a pilot test for laser sensors, it appeals on passengers to cooperate on its effort. At the core of its project is to stimulate a change in customer behaviour by strengthening public awareness. The agency carries out its agenda by handing out pamphlets and other advertising paraphernalia, and putting up help desks in each station so that passengers can report emergencies and ask for help.
