LED Triangular Warning Signs with Alternative QUEUE AHEAD display

Triangular Warning Vehicle Activated Sign (VAS) with LED Display

Vehicle Activated Sign (VAS) triangular warning sign (QUEUE AHEAD)

This interactive highway speed sign has been designed to mirror the triangular warning sign as seen in Diagram 584 described in the TSR&GD, which is displayed above the message QUEUE AHEAD. This display alternates with an alternative display of Diagram 670 “30” with the safety message SLOW DOWN. Each message displays for 1 second before alternating to the next display, which usually would have an overall display time of 6 seconds.

The light output of the directional LED display on the triangular warning sign is controlled via the inbuilt photocell, achieving best performance whatever the light or weather conditions.

The MVD is discretely positioned within the sign body, showing no external traces of a detector, yet allowing maximum detection. The MVD is easily programmed via a Netbook or Laptop computer, the lead is connected via USB Interface connector on the front of the sign which makes on-site adjustment simple and easy. This road safety speed limit sign can be radar activated and utilised for data collection.
