A report has warned that an ill-equipped transport network remains one of the biggest risks to the London 2012 Olympic Games.
The London Assembly Transport Committee foresees a host of problems likely to affect both visitors and regular commuters as nearly 5.3 million people come to see the Games.
There will be "extreme demand placed on a network already creaking at the seams", said committee chairman Val Shawcross.
The committee is also worried about the organisers' reliance on commuters to change their normal travel habits over the Games period for the transport plans to succeed.
Its report said that despite the addition of new transport infrastructure, London's networks are now operating at near maximum capacity and would struggle to cope with higher demand.
Besides problems for spectators and visitors "regular users are likely to experience more overcrowding and queuing", the report said.
During the nine busiest days of the Games, the public transport will need to accommodate an estimated more than a million Olympic-related journeys.
There are also 22 anticipated "travel hotspots" in 2012, including some of London's most congested roads and Tube stations which already suffer chronic overcrowding.
With people coming to the games from all over the country, using ajourney planner to find the best route looks like a good idea.
There are the busy King's Cross and Victoria stations, subject to regular overcrowding control measures, plus the Embankment and the southern approach to the Blackwall Tunnel which is already London's busiest junction, the committee said.
