Technical Traffic Solutions

Application

TTS is one of Europe’s most innovative and productive companies within the business of traffics, parking and city-owned equipment. PSC supplies the window displays for the “Green Light” series of traffic lights.

Most important requirements

TTS changes the traffic lights from the traditional glow lamp into a LED (Light Emitting Diodes) technique. Furthermore it is a flat panel design without the “sunshades” normally seen on traffic control lights. The requirements therefore are a display window solution which provides maximum readability in full daylight. Furthermore the solution must be suitable for outdoor use and impact resistant to prevent vandalism.

Solution

The solution chosen is based on a tinted polycarbonate filter as this material is very well suited for outdoor use and has a very high impact resistance. A special grey-shaded filter was chosen to provide good contrast enhancement. Finally, a Fine Mat surface treatment is applied to reduce reflections from incoming light.

Customer benefits

The traffic lights are difficult to break due to the polycarbonate display filter and the signal is easier to see because of the contrast enhancement. This adds to the security in traffics. In addition, the mat finish treatment reduces the need to clean the surface = less maintenance costs.

The modern traffic light “Green Light” won the Danish Design Award in 2000 for its minimalist and pure design and not to forget the sustained functionalism. Furthermore, TTS wins the European awards for environment 2002 with the LED technology used in “Green Light”, since it uses 60% less power than original traffic lights.
