A new document, which sets out plans to ensure that athletes and officials are able to get to London Olympic venues on time, has been published by the Games' organisers.

The Olympic Route Network (ORN) and Paralympic Route Network (PRN) proposals also aim to keep disruption to a minimum during the event, and ensure Londoners can go about their everyday business. Around 2.5 per cent of the capital's roads have been designated as part of the route plans, which will be kept roadwork-free and subject to traffic light timing changes. Temporary 'Games Lanes' will also be introduced.

More than 80,000 users will need to use the ORN during the Games time, including 18,000 athletes and team officials. Banned turns, the closure of side lanes and changes to pedestrian crossings are also mooted. London 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.

"The capital will be in the spotlight and temporary measures such as the Olympic Route Network will play a crucial role. But their contribution must also be weighed against a phenomenal investment in new transport infrastructure."
