The input network to the Ala-CC Bicounty Model is the All-streets, version 1 roadway network processed by Network Wrangler. This is much more detailed than the simple network used for PBA 2050 as part of MTC Travel Model 1.5.
Input Network (complete_network_with_externals.net) attributes:
File location: hwy/complete_network_with_externals.net

The highway network uses a numbering system whereby each county has a reserved block of nodes. Within each countyโs block, nodes 1 through 9,999 are reserved for TAZs, 10,001 through 89,999 are for MAZs, and 90,001 through 99,999 for transit access points or TAPs. The blocks are assigned to the nine counties per MTCโs numbering scheme, as shown in the table below.
Roadway, walk, bicycle, and transit network nodes are numbered by county as well and range from 1,000,000 to 10,000,000 as shown below.
| Code | County | TAZs | Network Node | HOV Lane Node |
