Availed Technologies Has Been Approved by Oregon DOT

We are happy to announce that the Availed AV-400 Rectangular Rapid Flashing Beacon is now listed as a qualified product on the Oregon DOT Green Sheets.

What is the Green Sheet Qualification Process?

Maintained by the Traffic-Roadway Section of the Oregon Department of Transportation, the Green Sheet Qualification process has a comprehensive evaluation process for a wide range of Traffic Signal, Illumination, and ITS equipment that includes physical, operational, and environmental testing.  For RRFBs in particular, the device is evaluated to ensure it is compliant with the requirements of the FHWA interim approval and the MUTCD and that it meets the requirements for mounting as shown in TM493.  Only prequalified RRFBs already listed on the green sheets will be approved for use for Oregon DOT projects under contract

The Importance of Energy Efficiency for RRFBs

As is very typical in the Pacific Northwest, many parts of Oregon have very low solar insolation during the winter months which presents a challenging environment for solar products such as the Availed AV-400 RRFB.  Key to ensuring reliable operation is energy efficiency, and this is where the AV-400 stands out.  All aspects of the product, from the wireless connectivity between units to the optical design of the LED lightbars has been designed to minimize power consumption.
