Encourage Londoners to take the stairs on the underground by installing oyster card readers at the top & bottom of each station's flight of stairs. Allowing commuters to record the number of steps they've climbed & descended! Also possible in offices
Install oyster card readers at the top and bottom of each station on the London Underground, also possible in office blocks. The card would be updated with the exact amount of steps between the card reader at the top and bottom of the flight of stairs at each station. Moreover, a separate tally could be recorded for stairs climbed and stairs descended depending on if the card was scanned at the top or bottom of the flight of stairs first.
The same principle could easily be applied in an office block, so individual businesses could independently encourage their employees to be more active on a day-to-day basis.
To maximise participation a website should be created whereby a friendly competition could easily be started between friends, family and colleagues.
