A new report has called on London Mayor Boris Johnson and Transport for London (TfL) to adopt a more dynamic approach to tackling the increasing traffic problems in the capital or face gridlock.
The London Assembly report asked Mr Johnson andTfL to map out how they plan to deal with the rising congestion over the next 20 years.
Mr Johnson's Transport Strategy previously predicted a 20% rise in traffic delays in the next two decades if nothing is done to tackle the transport issues, or 14% if measures are introduced.
The report by the Assembly's transport committee also calls for newly revised congestion projections.
The report highlights the need to have a more detailed response to the rising congestion in the capital.
Some members of the committee also called on authorities to look into the potential consequences of TfL's lane rental scheme.
A Transport for London spokeswoman said: "The Mayor's Transport Strategy sets out how further investment will be necessary to support and keep pace with London's economic and population growth and we continue to develop innovative ways to both increase transport capacity and encourage Londoners to choose more sustainable ways to travel."
