Planning

Florida Access Management Benchmarking Study

University of South Florida researchers will determine what improvements in FDOT access management policy or practice may be called for in relation to the FDOT mission and national best practice. The researchers will identify contemporary access management policies and practices in other states that may benefit FDOT in these improvement areas and how they are applied in practice, as well as any lessons learned. They will use this information to identify potential changes to current FDOT policy or practice that may help FDOT improve its performance.
