A driver speed feedback sign is intended to hand-off vehicle specific information back to drivers. The most widely recognized type of Driver Feedback Sign uses a radar assembly or other gadget for identifying the speed of moving vehicles and transfers that data to drivers through a variable message display.
Studies have found that Driver Feedback Signs can be very effective in decreasing speeds in an assortment of circumstances, particularly when the area's speed limit is posted related to the Driver Feedback Sign.
These digital speed signs are called by different names in different parts of the world. Some of the most popular names include the following:
● Driver feedback sign
● Vehicle Activated Sign
● Changeable message sign
● Your Speed sign
● Radar feedback sign
● Speed radar sign
● Radar speed display
● Speed sign or feedback sign
● Traffic calming sign
● Speed display board
● Dynamic speed display (DSDS) and
● Variable message sign.
While different studies have indicated that Driver Feedback Signs can play a very effective role in minimizing operating speeds in the long term, the best possible speed reductions are achieved shortly after a radar sign is installed. Allowing permanent installations can result in a proliferation of Driver Feedback Signs while decreasing the visual effect of the signs when the situations needed them most. To increase their effectiveness, these digital signs must only be utilized temporarily only at the locations that need them most.
Sign location has a very remarkable impact on the efficiency and effectiveness of any digital feedback signs. The signs offer the best of benefits when they are installed at spots where there is a need for an immediate reduction in the posted speed limit. Some of the most relevant examples include the following:
● Highway transition zones
● School zones
● Kids playground zones
● Construction zones &
● Medical establishments
Driver Feedback Signs need to be programmed well not only to display speeds which are beyond the posted limits but also to discourage the drivers from “racing” the speed display.
When speed beyond the permitted speed display threshold is observed, the sign may:
● Display a blank message
● Display value of the maximum speed
● Display threshold
● Display a text message such as “slow down” or “too fast”.
