Transport for London (TfL) has announced the introduction of a 20mph speed limit on 8.9km of road in central London, with work to begin later this year.

The move is a key part of Mayor Sadiq Khan’s Vision Zero ambition to eliminate death and serious injury from London's transport network. The announcement follows the publication of a consultation report “showing public support for lower speeds in central London”.

Congestion Charge Zone 

Sadiq Khan, said: “Every single death on London’s streets is one too many so I’m really pleased that Londoners have backed our plans to introduce a 20mph speed limit on TfL roads within the Congestion Charge Zone and at Aldgate Gyratory. By also bringing forward plans to lower speed limits in other parts London, we will help protect more people walking and cycling across our city.”

Active and sustainable

Penny Rees, Head of Network Sponsorship at TfL, said: “We know that lower speeds save lives, it’s that simple. As more and more people choose to walk and cycle around London we must reduce the risk of them being killed or seriously injured. It’s clear people agree that making our roads safer will encourage Londoners to travel in more active and sustainable ways.”

Pedestrians and cyclists

In response, Chair of the London Assembly Transport Committee, Florence Eshalomi AM (Assembly Member), said: “With the recent rise in road deaths, this is a good start from the Mayor and TfL but much more needs to be done to protect pedestrians and cyclists. Our roads will be made safer by reducing speed limits.

“TfL took on board the Transport Committee’s advice in the ‘Hostile Streets’ report to review all the speed limits on its roads. However, we suggest the Mayor considers going further to areas outside of the Congestion Charge Zone where walking and cycling should be safer.

“Every life lost on the road is tragedy. Particularly when the cause is a driver not obeying the speed limit.”

New signage 

The lower speed limit will be supported by new 20mph signage and road markings, as well as raised pedestrian crossings in seven locations where a high number of people walk, including near Embankment and Tower Hill Tube stations and outside the Tate Britain.

TfL will recalibrate all speed cameras in central London and use mobile speed cameras “to ensure that drivers are complying with the new safer speed limit”.

The new speed restriction will affect Victoria and Albert Embankments, Millbank, Tower Hill, Blackfriars Road and more.

Average speed of 7.4mph 

According to figures published by TfL, in Q1 2017/18 average traffic speeds for the 12 hours between 7am and 7pm across central London were 7.4 mph; a 0.2mph (3.2%) decrease year-on-year.
