Road and traffic signs have been used for a long time to inform motorist on how they are to behave and what to do at certain points, generally to make driving safer and less confusing. Speed limit signs were set up at street junctions to inform motorists and they are still in use today. However, within the last, the bloom of technology has influenced every area of our lives so much that speed limit signposts have gone digital. These devices are known as roadside speedometers, radar speed signs etc.
Speed display devices or radar speed display are speed sensitive devices and display speed information known as a feedback. They became a thing almost two decades ago and were installed with radars at strategic points for evidence-based and preventive safety reasons, to inform motorists or adjust their driving behavior. They are typically used in places where extra safety is needed such as schools, residential areas, narrow lanes, bridges, work, and construction zones etc.
Speed display information has to be in the most presentable and efficient way possible for effectiveness. Information display organizations and companies design speed displays in ways that they are versatile and dependable for displaying speed information and calming speeding motorists. The speed radars also serve as evidence that a particular motorist did not heed the speed limit.
Many speed display signs are designed to use solar energy as their major energy source alongside rechargeable batteries but these have been seen to fail during winter. The kind of materials used for their construction has to be durable because of the weather they are always exposed to. The following features show the standard of speed display devices as it is found in some high-end cameras like the ones from Traffic Logix.
#1: Quality construction
Speed display devices should be made with materials that are naturally corrosion resistant which includes aluminum and steel. These materials ensure their durability and warranty.
Even higher than functionality, the warrant for use of speed display devices shows its acceptability and eligibility for use.
#3: Good display and contrast
High-quality display that is not affected by headlight glares and even the sun is recommended for any display device.
#4: No stray LED light
This feature is especially important at night so that the radar lights do not stray unnecessarily into the area. The devices should have automatic mechanisms that dim its light at night.
- Slow down message
- Speed alert and driver awareness
The operation of speed display devices is such that it responds to the speed of an approaching motorist in a way to create a change in his speed giving emphasis to motorists moving at violated speeds.
