P31.25 Outdoor VMS for Highwayign Board IP65 Dynamic Message Signs Multi Color LED Board
Variable Message Signs (VMS) are crucial components of modern mobility management systems. LED variable message signs give information and warnings, provide directions, prevent accidents and control the flow of traffic. Not only are they good for road safety and the environment, they ultimately benefit us all in our daily mobility. They are very common on motorways but are also used in urban environments and in parking managament.
With introduction of the first LEDs in the transport sector, YAHAM developed its own high performance optical lens. Using a special lens design, the RGB colors are mixed, the light from the LED is bundled and projected without loss towards the driver on the road, exactly where it is needed.
This innovative technology has been patented by us and is used in any type of YAHAM’s variable message signs.

Wireless and remote control
1,It is the system that informs the drivers by converting the segment information shown in color on the traffic density map into text or image.
2,It allows drivers to plan their journey using this information. In this way, it helps to use the road network capacity more effectively, reduce traffic density and save time and fuel during the journey.
3,Additionally, it ensures the warning of the drivers about the changing road and weather conditions (accident, icing, fog, etc.) and contributes to the traffic and navigation safety.
