Three intersections in Washington County are a part of a trial run of high-tech sign detection units aimed toward bettering the expertise of bicycle riders.

— eighty fifth Avenue approaching Durham Highway, throughout from Corridor Boulevard

Washington County is utilizing merchandise from FLIR Systems, Inc., an organization primarily based in Wilsonville, Oregon.

The product, which ranges from $15,000 to $25,000 per intersection, makes use of an built-in thermal sensor that creates a warmth map primarily based on the power emitted from automotive and bike customers they are saying can distinguish between the 2. The sign then mechanically adjusts its timing sequence to securely get a bicycle rider by the intersections. The attraction of this method is that riders don’t need to push a button or place their bike over an induction loop to set off a inexperienced gentle.

The expertise isn’t good but and the County says their engineers will probably be working with FLIR on any needed tweaks all through the check interval. The Metropolis of Portland Bureau of Transportation additionally makes use of thermal detection alerts from FLIR. There’s one getting used at SE César Chávez Blvd and Lincoln.

Washington County has secured a federal grant to put in extra of those within the upcoming fiscal yr.
