The online interactive map was launched this week as it was revealed an additional three million journeys will be made on London’s transport networks at Games-time.

Passengers can go online to select their intended travel dates over the course of London 2012, and the map predicts how busy Tube stations will be.

The same information will be available for the London 2012 Paralympics later this year.

The map, launched by TfL, LOCOG and UK-wide transport agencies this week, can be found at getaheadofthegames.com.

Stations expected to be particularly popular with commuters during the Olympics are categorised as ‘exceptionally busy’, ‘busier than usual’ or subject to ‘restricted operations’.

The predictions are based on the number of passengers who typically use public transport and the road network during the summer, with allowances made for the influx of visitors expected in London, and the areas they are likely to travel to.

Transport officials have announced extended services during the Olympic Games to offset congestion.

There will be earlier Tube and DLR services running on Sundays, and services will run for about an hour later than usual throughout the week. Last trains from central London will leave at around 1.30am. An increased number of evening services will also be provided on the Jubilee, Central and District lines.

The site also offers ‘top tips’ to help passengers commute in relative comfort. They include: Find the travel hotspots, Plan ahead, Consider all your travel options, Avoid the busiest times if you can and Avoid driving into affected areas if you can.

Speaking at the launch of the site, London Transport Commissioner Peter Hendy said: “We’ve got two objectives, to host a great London 2012 Games and keep London and the UK moving.

Locog chair Sebastian Coe added: “The scale of the Games is unprecedented – across both Games there will be 14,000 athletes, 7,000 technical officials, more than 20,000 media and 11 million spectators… Success depends on all of us doing our bit to keep London and the UK moving.”
