Variable Message Signage (VMS)

Variable Message Signs (VMS) are one of the key elements of dynamic traffic management systems. Depending on the traffic situation, VMS inform, warn, and guide the motorists on highways, expressways and arterial roads of cities by displaying route /rerouting information, warnings (accidents, congestions), toll rates and special information.

Efftronics VMS works reliably without being affected even at high environment conditions and can be offered as text sign as well as monochromatic, bicolor and full color graphical displays.

Why EFFTRONICS VMS:

  • Proven track record of 10+ years product working life.
  • Expertise in designing and manufacturing for various communication networks like GPRS, Ethernet, GSM etc.
  • Supports all Indian languages and are according to UNICODE language standard.
  • Usage of high quality LEDs from grade A manufacturers like NICHIA / AVAGO etc.
  • Can customize for specific needs as required by transport authorities.

Salient Features:

  • High display stability and uniformity.
  • Reliable proven communication protocols.
  • The onboard firmware of the variable message sign provides diagnosis information and also reports any error status to the central system.
  • Use of constant current LED driver with static drive and restricting power dissipation with in safe limits of operation increases LED life time and reduces ageing effects and luminosity losses.
  • Brightness control from central place.
  • Easy to use image and message editor and download to variable message signs.
  • Configurable Scheduler to auto send information according to calender (day / date / day of week).
  • Addresses maximum of 256 displays in a network.
  • Sends SMS to configured mobile numbers in case of sign failures.
  • Easy access, quick and easy replacement of parts.
  • Reliable power supply and sign controller.
