Rectangular Rapid Flashing Beacons (RRFBs) Cost $10,000 Per Crosswalk.

A Rectangular Rapid Flashing Beacon (RRFB) is a traffic control device used to enhance the visibility of uncontrolled (mostly mid-block) marked crosswalks. RRFBs consist of a pair of pushbutton activated beacons that supplement the normal signs at a marked crosswalk and require power through a hard-wired connection or a solar assembly. The typical cost per crosswalk (with the cost of materials, equipment, and labor) is $10,000. 

Additionally, for VTrans, the average special provision costs for solar-powered RRFB's for locally managed sidewalk and shared-use path projects constructed between January 2014 and February 2019 was $7,767.70.
