PTV Visum supports the import of UTDF (Universal Traffic Data Format) files. These files are used by numerous software programs to import network updates, signal timing plans, and traffic volume information. You can import the following files:
-
Layout (node/link structure)
-
Lanes (node topology/geometry)
-
Phasing (signalization data)
-
Timing plans (schedule data)
-
Volumes (traffic volumes)
UTDF files are imported into existing networks.
