New safety measures are being trialled a roundabout following concerns over congestion, air quality and road safety.

Improvement measures at Redbridge roundabout include a new timing strategy where signals will be held on red for up to six seconds longer to provide more time for vehicles to exit at Redbridge Lane East.

There is a three-second increase in green light time to reduce congestion on the A12.

A406 traffic will receive a green signal once every two minutes – it is currently every minute – to reduce queues which normally go up to Redbridge Lane East.

Mayor of London Sadiq Khan plans to trial the changes, which will be monitored by signal engineers, for four weeks.

Lane markings will also be reviewed to make the roundabout safer with the mayor hoping to reduce “side swipe” collisions.

Mr Khan said: “Having visited the area and seeing the issues at Redbridge roundabout for myself, I made a firm commitment to produce an outline plan to address Londoners’ concerns about congestion, air quality and road safety.

“Working with Transport for London (TfL), I have now delivered on that promise within two weeks and we have already put in place a range of signalling measures to begin reducing congestion for residents, improving safety and cracking down on pollution.”

Ilford North MP Wes Streeting praised the mayor for implementing the changes swiftly.

He added: “We’ll have to see how the trial proceeds, but I sincerely hope that it contributes to reducing congestion around the roundabout in a way that helps make residents’ journeys easier and quicker.”
