A406 North Circular - London

Ampera will significantly reduce the power needed to light this busy road, significantly cutting energy costs and CO2 emissions

The ‘dull North Circular roar’ of the A406, immortalised in Guyanese poet Grace Nichols’ poem ‘Island Man’, reverberates for more than 25 miles of road running from Chiswick in West London to Woolwich in the east. In conjunction with the South Circular Road, the A406 forms a ring road around Central London, connecting the Outer London Suburbs such as Wembley, Willesden, Ealing, Southgate, Tottenham, Woodford and Barking.
The A406 incorporates a variety of road types, from six-lane dual carriageway to urban streets with adjacent residential buildings. London is one of the busiest cities in the world and the popularity of the road, in conjunction with the diverse route layout, means that vehicular congestion is a regular issue.
The section of the North Circular Road between the M11 and the A13 opened in 1987 to extend the route and ease congestion. It now passes the A12 on a flyover at the Redbridge Roundabout, moving south past Ilford and Barking to the A13.

Schréder worked with Ringway Jacobs to regenerate the road lighting on this section of the North Circular Road as part of the North East segment of Transport for London (TFL). Ringway Jacobs was responsible for the design and installation from conception to completion and the project is part of TFLs wider aim to completely regenerate London’s street lighting. An important aspect of this scheme is the connection of every TFL managed luminaire to its Harvard central management system (CMS). This will enable TFL to operate switching and dimming centrally and in real time, rather than having to rely on photocells attached to each individual luminaire. Previously, each luminaire would activate individually based on the reduction in the level of daylight, causing individual luminaires to come on and switch off at different times. With the new centrally managed LED scheme, TFL can operate dimming and switching depending on weather and traffic requirements.
Schréder supplied the Ampera Maxi (128 LEDs) to replace the previous lighting scheme with 250W high-pressure sodium lamps. The new scheme will significantly reduce the power needed to light the road.

When London’s street lighting regeneration project is complete, it is estimated that the lower energy consumption of the LED luminaires will contribute to savings of £1.85 million, and dramatically cut CO2 emissions by 9,700 tonnes, each year, supporting the Mayor of London’s target of a 60 per cent reduction in CO2 emissions by 2025.
