Traffic light upgrade saves energy at M-way junctions

Upgraded traffic signals at junctions on motorways and major A roads in the south of England will not only save energy for the Highways Agency but also contribute to greater safety for drivers.

Siemens Mobility, Traffic Solutions will supply and install replacement Extra Low Voltage (ELV) traffic controllers and signal heads at more than 40 sites on the M3 in Surrey and Hampshire, the M4 in Buckinghamshire, Berkshire and part of Wiltshire, the M27 and A27 in Hampshire and the A3 in Surrey as part of EnterpriseMouchel's Managed Area Contract (MAC) with the Highways Agency.

The new equipment is being installed following surveys by the Siemens Design Services Group and is expected to be validated and fully completed in 10 months. Siemens will also provide a new Urban Traffic Control (UTC) system in Basingstoke.

Highways Agency construction manager Guy Berresford said: 'this work is part of our commitment to help improve safety and journey reliability. The new LED traffic lights use less power and will be more visible to drivers in bright, sunny conditions. This has the double advantage of saving energy and increasing safety for road users.'

The use of ELV provides reduced power and cabling costs as well as improved lamp monitoring of very low power LED traffic and pedestrian signals. ELV also provides increased electrical safety for both members of the public in the event of any damage to the installation and personnel working on or around the junction.
