Dept. of TransportationAbou-Senna, HatemUniversity of Central FloridaUS Transportation CollectionThe Florida Department of Transportation (FDOT) has set a goal to optimize existinginfrastructure to improve safety, capacity, and reliability while reducing congestion and delays.FDOT is pursuing this goal through Transportation Systems Management and Operations(TSM&O), a program of strategies to improve the performance of multimodal structures.TSM&O offers strategies to a common interruption of traffic flow: left-turn movements. Trafficflows must be regularly interrupted to allow cross-street traffic to proceed and to allow leftturns onto the cross street. Overpasses can be utilized to separate some of these conflictingmovements, but left turns must still be provided at street level
