The traffic light - a small energy wonder

The participants of the 2015 UN Climate Change Conference in Paris resolved to limit global warming to a maximum of two degrees. To reach this goal, highly energy efficient innovations in road traffic are needed. Siemens wants to reduce the energy consumption of the more than 60,000 intersections equipped with traffic lights in Southern Germany. With a low energy consumption of just one to two watts per light signal, about 1,600 kilowatt-hours (kWh) can be saved per year at a typical intersection. By way of comparison: A single-person home consumes just over 1,000 kWh a year.

1-watt technology: The world's thriftiest traffic light

In addition to power costs, the 1-watt signal light units also reduce service costs, thanks to digital LED drivers. Optical monitors continuously check the state of the LEDs. It is conceivable that in the future it may be possible to predict when units will fail to enable preventative maintenance of signal light units, thus reducing the risk of chaos caused by a traffic light failure during rush hour.

'Green wave' for cyclists

It's just not fair. For decades cars have been whizzing through cites, unimpeded by constant stops at red lights. The phenomenon Germans call the Gruene Welle, or "green wave" (when a string of traffic lights turns green in sequence), has become an everyday occurrence in big cities, thanks to ingenious traffic control systems. Cyclists, however, constantly have to put on the brakes for red phases. Now, those days are over. Thanks to Siemens technology, cyclists can now experience the joy of the Gruene Welle on German streets.

Making life easier for cyclists

Every driver hopes to arrive at the next traffic light as it turns green, to catch a green wave. Carefully planned green waves ensure free-flowing traffic, reduce unnecessary braking and acceleration maneuvers, and thus make a proven contribution to reducing fine particulate and nitrogen oxide emissions. This effect is achieved by setting a series of traffic lights so that at a specific, constant traveling speed they can all be reached in a green phase.

How does the green wave for cyclists work?

As the cyclist with the SiBike app approaches an intersection, the traffic light either automatically turns green in a matter of seconds or a green phase lasts longer. SiBike takes advantage of the benefits of satellite navigation technology. The cyclist's smartphone determines its position via GPS and checks whether the bike has passed a specific trigger point at a predetermined speed. When the bike passes the trigger point, the app reports its activation to the traffic control center. The traffic control center then issues a command to the traffic light controller and ensures that the cyclist gets a green light.

1-watt technology: The world's thriftiest traffic light

A shake-up in transportation systems: Siemens engineers have managed to reduce the power consumption of a traffic light to just one to two watts. This achievement, made possible with "1-watt technology", has enabled Siemens to revolutionize the market and improve the energy efficiency of standard 230 V LED technology by up to 85 percent.
