The Welsh Speed Indication Device will display a real-time illustration of the approaching speed of an oncoming vehicle when exceeding a pre-set threshold limit. However, if the approaching vehicle is above a second higher threshold limit, the sign will display both SPEED and “ARAF SLOW”.
When the vehicle then slows down and the speed falls below the secondary threshold limit, the sign will display “DIOLCH THANKS” with the real-time speed. In addition, this dual colour speed display sign is available in red and green.
The light output of the directional LED display is controlled via the inbuilt photo cell, achieving best performance whatever the light or weather conditions. Furthermore, the MVD is discretely positioned within the sign body, showing no external traces of a detector, yet allowing maximum detection. The road safety speed limit sign can be radar activated and utilised for data collection. It can also operate as a remote data collection facility and requires virtually no maintenance.
