Tunnels traffic signs are installed in the interior or entrance of the tunnel. The signs are produced in compliance with European standard EN12966. Modular design ensures simple maintenance by simple replacements of the parts. LEDs with high luminous intensity and long life time. Special system to protect LEDs from temperature peeks that might happen during device operation. Possible brightness control: manual brightness control, brightness control according to actual day time using precise algorithm, brightness control according to external illumination measured by 1 or 2 light sensors and external brightness control. Communication interfaces: RS232, RS485, Ethernet, Wi-Fi, GSM/GPRS.
Matrix tunnel signs
Matrix signs for tunnel show text information or indicate a hazard ahead on the road that may not be readily apparent to a driver. Size, text and symbols are custom made.
Predefined tunnel signs
Predefined signs for use in the tunnels are TRS-SD45. This signs usually consist from two parts, one of them shows speed limit and the second shows a certain commands.
Lane control signs
Directing or forbidding the passage of the vehicles in the tunnels. Possibility of two or three LEDs rows. Possible shows: green arrow (free passage), red cross (forbidden passage), yellow arrows (directing towards left or right side of the road)
