London commuters are being urged to boycott the bus and Tube on 20 December by a new transport pressure group.
Protesters hope to empty the Tube
Commuter Voice said it was time for people to vent their anger about the everyday frustrations of travelling across the city.
Organiser Gari Sullivan said the group aimed to bring pressure on mayor Ken Livingstone and Transport for London.
But TfL said its results were the best for "six or seven" years and a boycott would not solve anything.
Mr Sullivan, 40, from Wimbledon in south-west London said: "There seemed to be so many people who were commuters who were moaning, complaining and stressed out.
"I wanted to give them somewhere where they could express their frustration."
Mr Gari said there had been 57,000 visits to his website since October, from commuters fed up with the hassle of travelling across London.
He hopes London commuters will draw inspiration from protests in Sydney, where thousands of rail travellers refused to pay fares.
Commuter Voice is calling for a three year price freeze on Tube fares, and index-linked fare rises from 2008.
Other demands include more bus lanes and a call for employers to do more to help people work from home.
A TFL spokesman said it successfully transported 10 million people across the capital every day.
This included six million on the tube, three million on the buses and one million on the Dockland Light Railway and tram services.
The spokesman said the problem was under-investment in London transport, and TfL planned to invest £10bn over the next five years.
He said: "I do not think the proposed protest by commuters would solve anything. There are problems and we need tackle them."
