Florida Department of Transportation's LOSPLAN (Level Of Service PLANning) Software


LOSPLAN is a suite of three software programs that perform level of service analyses targeted for planning and preliminary engineering applications.  The three programs are ARTPLAN, for signalized arterial facilities, FREEPLAN, for freeway facilities, and HIGHPLAN, for two-lane and multilane highway facilities.  The LOSPLAN calculations are based largely on the analysis methodologies of Highway Capacity Manual, but also incorporate numerous simplifying assumptions and enhancements based on Florida Department of Transportation research. The software is developed by Dr. Scott Washburn at the University of Florida's Transportation Institute.
