nopeusnäytöillä

Nopeusnäytöt, often translated as speed displays or radar speed signs, are traffic calming devices designed to inform drivers of their current speed. These electronic signs typically use a radar unit to detect the speed of approaching vehicles and then display that speed back to the driver in large, highly visible numbers. The primary goal is to increase driver awareness of their speed and encourage them to reduce it if they are exceeding the posted limit.

These devices are commonly found in areas where lower speeds are desirable for safety reasons, such as school zones, residential streets, and construction areas. The visual feedback serves as a non-punitive reminder, aiming to modify driver behavior through self-correction rather than enforcement. Studies and anecdotal evidence suggest that speed displays can be effective in reducing average vehicle speeds and the number of speeding violations.

Some speed displays also incorporate additional features. These can include flashing lights or messages like "Slow Down" when a vehicle is detected traveling above a predetermined threshold. More advanced versions might log traffic data, providing valuable information for traffic management studies. The effectiveness of speed displays can vary depending on factors like placement, visibility, and the specific community context. They are generally considered a supplementary tool within a broader traffic calming strategy.
