Three in four London road junctions will have traffic sensors by 2018 as transport chiefs bid to reduce the impact of a £4bn programme of works.
Transport for London said today that the technology would allow it to detect real-time traffic conditions and optimise traffic light timings across the capital.
The technology is one of a number of ways the body is looking to minimise disruption from extensive works to improve London’s roads.
Iconic road systems such as the Imax roundabout at Waterloo and the northern roundabout at Elephant & Castle are among 50 that will undergo improvement under an initiative announced last year.
This programme, part of a wider effort to achieve a 40% cut in the number of people killed or seriously injured on the roads by 2020, aims to improve the efficiency, safety and reliability of the network.
Transport for London managing director of surface transport Leon Daniels said: “This programme is changing London for the better and we must work with Londoners, businesses, boroughs and others to help people adapt.
“However, just like with the recent upgrades on the Underground, Londoners will find that there are more modernisation projects underway that affect their journeys.
“Just as we did during the London 2012 Games, we’re utilising the latest technology to manage the road network and limit disruption.
“We’re also working with businesses to re-time deliveries outside of peak times and are providing a huge range of detailed travel information, advice and tools so that, wherever possible, road users can plan ahead and avoid hotspots.”
