Driver Feedback Signs – DFS signs

driver feedback signThese driver feedback signs or DFS signs are traffic calming devices that are proven to give drivers instant feedback as to their speed thereby encouraging a reduced speed and traffic calming where appropriate without the threat of a speeding conviction.

Using our patented “Lite Plaq” technology, these signs are slimline and pleasing to the eye, whilst providing an effective visual indication in excess of 100 metres of approaching vehicle’s speed whilst activated by a Doppler radar detection system which is coupled to a decoder that illuminates the LED’s (light emitting diodes) with the relative speed and sampled at 0.5 second intervals

The detection range can be set at various distances as well as the required trigger speed.  The DFS displayed speed can be set to KPH or MPH by means of a dipswitch setting. The minimum speed can also be set with a dip switch. To avoid encouraging young drivers from challenging each other to achieve the highest speed the sign can be simply programmed to illuminate two dashes if the approach speed is 20 mph greater than the desired setting.

The DFS display LED’s illuminate in red for an over speed and green for speeds below the set legal speed limit for any particular location.

These DFS units can be set to the various parameters using “Bluetooth” connectivity from a tablet PC.  Moreover, the DFS memory card stores the number of over speeds and the number of decelerating vehicles that are responding to the feedback, thereby providing useful data as to the effectiveness of the DFS in any particular location.

These driver feedback signs are available for mains powered locations, or solar powered locations where it is not cost effective to provide a mains supply.
