Yield signs get around 30% driver compliance. RRFBs get 72-82% or higher. A HAWK signal costs $60,000-$100,000 installed. An RRFB costs $8,000-$15,000. When the location doesn't warrant full signalization, the RRFB is often exactly the right call. #RRFB #PedestrianSafety #CrosswalkDesign #MrBarricade
