Variable Message Signs are key elements of dynamic traffic management systems . Depending on the traffic situation , the variable displays inform , warn , and guide the motorists on highways and expressways . Our VMS are certified by INTRON according to the requirements of EN 12966 and provide brilliant legibility , efficient use of energy and an excellent luminance ratio .
2. Features
1. Ultimate optical performance – exceeding the highest optical classes according to EN 12966
2. Conformity to EN 12966 : more than 100 class-combinations of different color , luminosity , contrast , beam width , pixel pitch , LEDs ,forward current , etc. have been tested and certified by SGS/INTRON.
3. Cutting edge performance – Anti-aliasing for picture smoothing , Optical System , Optimized Pixel Density , True Type Fonts ,Display Luminance Intensity Regulation , Current Source Monitoring Technology , Surface Mount LEDs – provide extraordinary advantages over standard LED signs in situations where motorists have only a brief period of time to absorb and react to information.
