London 2012: Boris Johnson records Olympic travel advice
London Mayor Boris Johnson has recorded public transport announcements to warn travellers to plan their journeys ahead of the Olympic Games.
One message says: "We're welcoming more than a million people a day to our city and there is going to be huge pressure on the transport network.
"Don't get caught out. Get online and plan your journey."
After the messages were first broadcast on Tuesday, many users took to Twitter to criticise them.
OwenPSanderson, a structured finance reporter from London, tweeted: "Boris's dulcet tones broadcast on the tube this morning. Apparently going to be busy next month. Good thing I stopped living under that rock."
While Tony Broderick tweeted: "Boris has recorded announcements on the tube about dodging fares. It's like living in a Orwell novel."
And travel consultant Dodi wrote: "Bad enough travelling on the tube to work during the Olympics. You're now gonna be graced with Boris' voice while you're at it."
Going Underground blogger Annie Mole wrote the mayor would have to record a message to warn travellers to be wary of people stealing personal possessions such as laptops.
But Mr Johnson said: "This summer will be a hugely exciting time for London, and with a million extra visitors a day to our great city, our roads and public transport services are going to be exceptionally busy, and journeys may take longer than usual.
"So it's vital that businesses and Londoners don't adopt a 'wait and see' approach and play their part in putting on a fantastic Olympics."
Lord Coe, chairman of Games' organisers Locog, said: "Thousands of athletes around the world are at the final stages of planning for the Games. Their plans will be meticulous, leaving no stone unturned.
"Businesses in London also need to fine tune their plans for the Games. There is a huge amount of information available to help people do this."
London 2012 - One extraordinary year
Olympic organisers believe Tube and rail "hotspots" during the Games will be Bank, Earl's Court and London Bridge.
It is estimated that up to three million extra journeys are expected to be made in London alone on the busiest days until the closing ceremony on 12 August.
Londoners have been advised to try to work from home, stagger working hours, work longer but fewer days, take annual leave and swap to walking and cycling where possible.
The Olympic Games run from 27 July to 12 August and the Paralympic Games from 29 August to 9 September.
