Olympics organisers have revealed the 'hot spots' that people should try and avoid in the city during the Olympic Games.
Up to three million extra trips are expected daily while the Games are going on, which means there will be an estimated 15 million journeys being made each day from July 27, when the Games begin, to their end on August 12.
A modified London Tube map highlighting the hot spots during the Games pinpoints 23 Tube stations that will be 'exceptionally busy' during the Olympics, while many more stations have been classified as 'busier than usual'.
Among the tube stations that will be 'exceptionally busy' are: Oxford Circus, Earls Court, Bank, London Bridge, Canada Water, Clapham North, Holborn, King Cross, Baker Street and Euston - you can see them all in the modified map.
Overground stations will also be affected while organisers have highlighted roads that people should "avoid if possible" and others where users can "expect delays".
There is also advice on how best to get around venues outside of London such as the football stadiums being used around Britain and the sailing complex in Weymouth.
The website suggests five ways that people can make their journey easier. They are:
Transport Secretary Justine Greening said: "I encourage businesses and individuals to plan how they are going to travel this summer, so we can deliver a fantastic Games that the whole country can be part of and proud of."
Organising committee chair Sebastian Coe added: "London and the UK is gearing up to welcome the world this summer when 15,000 athletes, 7,000 technical officials, thousands of media and millions of spectators will be travelling on our transport networks.
"As the success of the Games depends on all of us doing our bit to keep London and the UK moving, I'd like to urge everyone to plan now."
After the Olympic Games between July 27 and August 12, the Paralympics will be held from August 29 until September 9.
