The public transport Games
The aim is that during this time, all spectators will travel to events on public transport.
Investing billions of pounds into upgrading the city's transport network will help achieve this and leave a lasting legacy of improvements for Londoners.
Mayor Boris Johnson said: 'Thousands of visitors from around the world will descend on our great city in 2012 and transport will be critical to ensuring we deliver a Games that London can be proud of.
'Improvements like those happening at Stratford regional station, the doubling in capacity of the Docklands Light Railway, the superb new East London line and the new King's Cross ticket hall are already delivering an early legacy of improvements for Londoners.'
