Underground technology
There is a fascinating documentary series running on the BBC at the moment called the Tube. It gives quite a unique perspective on what it’s like to work as part of one of the world’s largest transport networks, dealing with headaches such as grumpy commuters and technical failures.
Monday night’s episode focused on fare evaders. Featuring a mix of sheepish and aggressive tube users and the London Underground’s very own Cagney and Lacey, the programme gave an interesting insight into the tools the London Underground has at its disposal to crack down on fare evaders.
From a tech point of view, it was surprising to see that the NFC-powered Oyster Card, which has been dubbed by some as Big Brother’s evil invention, isn’t necessarily the answer to Cagney and Lacey’s prayers after all. Because of data protection issues, London Underground can’t simply pin point where a person is or link a card with a person’s name and address details in real-time with CCTV.
Instead, when spotting suspicious or fraudulent activity linked to a particular Oyster Card, Cagney and Lacey need to trawl through hours of grainy CCTV footage and try to spot the culprit. They then need to just wait (and wait…) for that offending Oyster to be used again and arrange a stake-out to catch the person in the act.
I somehow would have thought that in this day and age the process would be more advanced, perhaps featuring an action-film type lock-down with alarm bells and flashing lights when that suspicious looking bloke with the red head phones passes through the gates at East Finchley.
It seems that the London Underground still has some way to go before this type of scenario becomes a reality. Even though fare evaders cost the company around £4 million a year, they probably have enough on their plate with the Olympics right around the corner.
Still, it was a fascinating documentary! You can view it on the BBC iPlayer here: http://www.bbc.co.uk/iplayer/episode/b01cyt4l/The_Tube_Episode_2/
