Rectangular Rapid Flashing Beacons Experimental Feature Project

The Dowling Road and Seward Highway Interchange has anecdotally poor compliance for yielding to pedestrians and bicyclists when motorists leave the roundabout. Eight rectangular rapid-flashing beacons (RRFB) will be installed at the North and South crosswalks. The primary objectives of the experiment feature are: (1) assess the compliance of motorists prior to installation of RRFBs; (2) install RRFBs during the 2023 construction season; and (3) long-term performance & compliance monitoring.
