RRFBs are <br />applicable on roadways with higher pedestrian <br />demand, traffic volumes, and traffic speeds. It is a <br />proven safety strategy for reducing crashes per the <br />FHWA with a typical crash reduction of 47 percent. <br />Average cost is $15,000 to $50,000 per crossing or <br />$80,000 to $100,000 for an overhead system. <br /> <br />Source: Minnesota Department of Transportation <br /> <br />Pedestrian Hybrid Beacon (PHB) <br /> <br /> <br /> <br /> <br />A pedestrian hybrid beacon (PHB), formerly known <br />as a HAWK, is a beacon installed to warn and <br />control traffic by having vehicles stop with a red <br />light. It consists of two red lenses and one yellow <br />lens and is dark until pedestrian activated. PHBs are <br />applicable on high speed, multilane roadways, with <br />higher traffic volumes and where RRFBs are no <br />longer a viable safety solution, such as when gaps <br />in traffic are not sufficient. If PHBs are not already <br />familiar to a community, agencies should conduct appropriate education and outreach as part of <br />implementation. It is a proven safety strategy for reducing crashes per the FHWA with a typical <br />crash reduction of 55 percent. Average cost is $100,000 to $170,000 per crossing. Of note, if <br />pedestrian demand is higher, a pedestrian signal should be explored in lieu of a PHB. A pedestrian <br />signal is a traffic signal placed at a pedestrian crossing and does not refer to a signalized <br />intersection.
