How will the Olympic Games change your travel habits?
Today we launch our Olympics commuters strand to find out exactly how Londoners will be affected during the Games.
We are working with University College London and will be tracking four different commuters over the period.
You can see the first piece produced by Warren Nettleford here:
Transport for London and the train companies need commuters to change their habits or the queues and the disruption will be much worse.
On Friday they warned motorists to stop driving into central London. I did a piece on this last week.
In Vancouver they called the tactic "the big scare". In London the approach is more balanced.'Unpredicted people'
Transport bosses said the situation will change from day to day but that London is still very much open for business - that means they want commuters to plan ahead.
But they also need three million fewer journeys from everyday commuters for the system to feel the same.
And in terms of planning, there is an element of the unknown.
This is the biggest transport challenge since World War II.
And the element of uncertainty comes not from the ticketed events where they can roughly estimate who will be using what and where, but from the unticketed events like the screens at Hyde Park.
As during the Jubilee, there could be thousands of extra "unpredicted" people wanting to be in central London to experience the party.
This is when at some locations, on some days, there will be more queues and more delays.
How bad this will be is the great unknown.
But let me know if the warnings and the advice are making a difference to you.
