Multi Coloured DSD speed display SID Speed Indication Device

Large LED DSD SPEED DISPLAY with SLOW DOWN Safety Message & Sad / Smiley Face Option [EN12966:2014]

The Multi-Coloured DSD Speed Display Sign is an interactive vehicle activated sign that displays 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 the vehicle’s speed and” SLOW DOWN”. When the vehicle then slows down and the speed falls below the secondary threshold limit, the sign will display “THANK YOU” with the real-time speed.

The “SLOW DOWN/THANK YOU” message can easily be substituted by the “SAD/ HAPPY FACE” option by use of a hidden switch. This traffic calming dual colour DSD speed display sign is available in red and green and can be radar activated or utilised for data collection. It can also operate as a remote data collection facility and requires virtually no maintenance.
