Dept. of TransportationBenghuzzi, EzzeldinUS Transportation CollectionThough drivers may disagree, traffic signals are timed to optimize throughput at intersections. Timing settings depend on the normal traffic flows, but these flows can be severely affected by work zones, which often block lanes. The 2010 Florida Department of Transportation (FDOT) Design Standards provide information regarding traffic control through work zones on multilane arterials. However, there are currently no quantitative guidelines for optimizing signal control around work zones. Therefore, University of Florida researchers sought to formulate recommendations for development of signal control plans, including phasing, signal timings, and channelization. The research focused on multilane arterial streets.75
