- Transportation hubs (ports and terminals) moving people or goods;
- Interregional corridors (highways, rail lines, waterways and urban fixed guideway transit facilities) connecting major origin/destination markets; and
- Intermodal connectors (highways, rail lines, or waterways and other exclusive use facilities) linking hub-to-corridor; hub-to-hub; or strategic military installation-to-corridor
