Radar-based speed cameras to be trialled by TfL and Met

TfL, working in partnership with the Metropolitan Police, is trialling a new type of radar-based speed cameras at up to ten sites around London. Evidence shows, it said, that exceeding speed limit or travelling too fast for the conditions is a factor in around half of all fatal collisions.

The new radar-based speed cameras will be installed over the coming weeks at sites in Haringey, Tower Hamlets, Havering, Croydon, Hammersmith and Fulham, Brent, Hackney, Ealing, and Sutton. All sites are located on 20mph or 30mph roads and have been identified on the basis of suitability and risk, according to TfL.

SUV Charge for London Considered by Mayor

Plans are being explored to introduce a new SUV charge in London as part of efforts to reduce congestion and improve air quality.

High Air Pollution Alert Issued by Mayor

A high pollution warning has been issued across London, urging residents to take precautions as air quality levels rise.

Boris Bus to Be Removed from Select Routes

The iconic Boris buses are set to be phased out from certain routes as Transport for London reviews efficiency and environmental impact.

The current spot speed cameras at these sites use sensors embedded in the road surface to detect the speed of all passing vehicles. The new cameras combine 4D radar and a 4k colour camera that requires no visible flash or white light, nor an in-ground sensor or road marking. This, TfL says, offers “increased reliability and a more effective method of detection,” as well as “better quality images, which in turn improves the police enforcement process for drivers caught speeding.”

They can provide coverage of up to five lanes of bi-directional traffic flow from a single camera, where the current kind can only monitor up to three lanes of traffic and requires sensors in each lane.

All enforcement signage will be checked and cameras will be calibrated before the police begin enforcement, as per TfL/MPS policy.
