Siemens delivers 25,000th traffic controller

A Siemens type C940ES traffic controller, part of a shipment to the Glückstein district of Mannheim, was also the 25,000th traffic controller of the series. The controllers will be used to upgrade traffic signal control at all junctions in Glückstein, and is specifically designed to meet the requirements for controlling 40-volt LED (light-emitting diode) lighting equipment, which saves up to 90 per cent of the energy consumed by conventional bulbs.

A 189 Siemens type C940ES traffic controller, part of a shipment to the Glückstein district of Mannheim, was also the 25,000th traffic controller of the series.

The controllers will be used to upgrade traffic signal control at all junctions in Glückstein, and is specifically designed to meet the requirements for controlling 40-volt LED (light-emitting diode) lighting equipment, which saves up to 90 per cent of the energy consumed by conventional bulbs.

The high safety level of the controllers installed in Mannheim will check changes in the behaviour of the LED signals at the extremely rapid rate of 1,000 times per second, and report any conflicting signal states and defective lamps.

    Substantial savings from smarter street lighting
    As authorities strive to reduce expenditure and carbon emissions, Colin Sowman looks at some of the smart ways of managing street lighting while containing costs and maintaining safety. Street lighting can account for 40% of an authority’s energy consumption. So, faced with the need to reduce outgoings, some authorities are looking for smart ways of managing street lighting or even turning off swathes of street lights in the small hours. Back in 2008 the E-street Initiative report concluded that authorities
