Boris Johnson's transport plans includes a review of bus services
Dedicated cycling routes into central London and opening up bus lanes to motorbikes are among Boris Johnson's plans to improve transport in London.
In a paper, Way To Go, the mayor stressed the importance of moving ahead with Crossrail and Tube improvements including air-conditioned trains.
But he admitted "huge challenges" still remained.
The London Assembly Labour group said Mr Johnson's plans lacked any vision or ambition.
Mr Johnson said "packed trains, clogged streets and roads where cyclists take their lives into their own hands" hampered the quality of life for commuters and other travellers.
In his paper, he announced plans to develop an orbital rail equivalent to the M25 and to continue rolling out the Oyster card system across the private rail franchises.
Other plans included re-phasing traffic lights, a review of bus services and clamping down on companies which leave holes in streets.
"I want to improve Londoners' quality of life and we will be investing billions in achieving this through better transport - boosting capacity on the Tube network by 30%, delivering Crossrail, which will revolutionise the way we get across the city, and in a host of other measures to improve the experience of navigating the capital," he said.
But BBC London's transport correspondent Tom Edwards said the paper also revealed that some major schemes could be scrapped.
"What this document also says is that this administration is no longer going to fund projects that do not have central government funding," he said.
"What we are talking there, although we cannot confirm it, are projects such as the cross-river tram project and the Docklands Light Railway extension to Dagenham Docks."
Labour's transport spokesperson Val Shawcross said the plans were "a huge disappointment for London's travelling public".
"Any serious transport strategy for London would include a commitment to additional major transport schemes and a clear aim to shift people from private cars to public transport, walking and cycling," she said.
She said Mr Johnson talked about investing in major projects but only listed a few schemes such as Crossrail, which she said were under way before he was elected.
