Sources of GIS Databases
► GIS databases can be used to enhance model highway
networks.
► The Florida Department of Transportation has purchased
GIS Mapping Files (GIS Street Data Bases) for the entire
state. The files are supplied by TeleAtlas/GDT.
► GEOPLAN Files are now downloadable and free from
the University of Florida. The files contain over 300 GIS
layers of information on each county in Florida.

Highway Network Input/Output Files
► The Highway Network Model requires the following input
files:
spdcap_yya.dbf
~ speed/capacity lookup tables
turn_yya.pen
~ turn penalties and prohibitors
tolllink_yya.dat
~ toll link and toll plaza information
vfactors.csv
~ variable factors file
► The Highway Network Model will generate the following
output file:
unloaded.ayy.net
~ unloaded network database
Note: Though the vfactors file is used as an input for updating the network, the
information it contains is used specifically during highway assignment. As such, the
vfactors file is discussed in greater detail in Lesson 9: Assignment.
