The Miasma Beach Transportation Model
Task 2. DEVELOP 2004 BASE YEAR transcad NETWORK and SKIMS
The objective of this task is to create a transcad network file that will convert the GIS information that represents the Transportation System T into a form suitable for subsequent transportation analysis.

2.1 Create transcad Network File
Set the Highway/Streets layer as the Working Layer. If you don't see Networks/Paths in your menu bar (on top of the transcad window), go to Procedures and check it.
