Spectators attending London's 2012 Olympics have been urged to leave their cars at home and travel to the games on foot, cycle or public transport.
One train will serve the park every 15 seconds, Games planners say
The Olympic Delivery Authority (ODA) said it hoped the event would be a "Public Transport Games" - but stopped short of saying it wanted to ban cars.
The ODA published its Olympic Transport Plan, detailing planned improvements to public transport links, on Tuesday.
As many as 500,000 spectators are expected to attend events each day.
Another 50,000 athletes, officials and media are also expected to be travelling to the Olympic venues.
The report outlines new trains, railway lines and stations, as well as improved walking and cycling routes and transport options on the River Thames.
Proposals by the ODA include:
- Free travel card for all Olympic event ticketholders
- Personalised travel plans, probably sent to ticketholders' mobiles, showing the quickest route from their starting point to the venue
- Flat-rate train fares to London from across the country
The ODA said the Olympic Park in Stratford, east London, is expected to be served by one train every 15 seconds during the course of the Games.
ODA chief executive David Higgins said: "The Olympic Park will host the world's biggest sporting event in 2012, and will become a new destination in east London after the Games have gone.
"It is essential we put in place world-class transport links to make this one of the best-connected parts of the capital.
"We want London 2012 to be the Public Transport Games. This is not about banning people from using their cars but about making public transport, walking and cycling the most attractive option for spectators travelling to the games."
Sebastian Coe, chairman of the London 2012 Organising Committee, said: "Our transport plans were a key strength of our bid to win the Games.
"The progress we have made on a wide range of transport schemes demonstrates our ability to hit key milestones in delivering world-class transport for the Games and beyond."
