Siemens launches one watt traffic signal

189 Siemens claims to have improved the energy efficiency of traffic lights by more than 85 per cent by using what it calls one-watt technology. The first pilot projects are already running in Bolzano, Italy and Bietigheim-Bissingen near Stuttgart in Southern Germany.

According to Siemens, a typical intersection with bulb-based technology and around 55 traffic signals (red, amber and green) can now avoid more than 6,000 kilograms of harmful carbon emissions a year. One-watt technology uses digital LED driver modules, which Siemens says eliminates the need for load resistors and switching elements in the signal light units which consume most of the energy.

Compared with the 60 watts sometimes consumed by incandescent bulbs, the electricity required by individual traffic light signals can be cut to just one or two watts. State-of-the-art LEDs with extremely low power consumption still retain full light intensity, while the one-watt light units also reduce service costs.

    Delcan’s Joe Lam, who managed the first computerised signal system in the world, provides an expert insight into adaptive signal control. There are no gadgets in the world that regulate our daily behaviour as much as traffic signals, except perhaps our mobile phones. It has been estimated that the daily commuter goes through at least 10 signals on his journey to work. However, unlike mobile phones, traffic signals cannot be ignored or switched off by their daily users, at least not without legal consequence
