Rectangular Rapid-Flashing Beacons Experimental Feature

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 and compliance monitoring.
