Driver Feedback Signs

Keep it QUIET!
Presenting Noise Limit Warning Sign

The noise limit warning sign detects oncoming vehicles and, based on the noise they are making (e.g. noise levels above 84dB), displays a warning message for drivers to ease up on the accelerator while passing through a village or neighbourhood whose residents prefer a calmer and quieter environment.

The noise limit warning signs are already successfully installed in Austrian villages where there were many complaints from local residents about noise from motorcycle drivers, from spring until autumn.

Dot-Matrix Display

Each matrix module we install consists of 8x16 pixels capable of displaying Latin, Cyrillic or Arabic alphabet with animated text or graphics, while LED digit size of 390mm ensures excellent visibility to all oncoming drivers.

Our efficient power consumption system guarantees flawless operation even with several weeks of snowy, rainy of foggy weather, when there is limited sunlight available for the solar cells to absorb.

The wide viewing angle LEDs provide excellent visibility in all weather conditions, while adaptive photosensor technology adjusts the brightness of the LEDs in more than 100 different levels of luminosity.
