BOX 3-A - National Transportation Atlas Database

RITA/BTS's authorizing legislation calls on the agency to develop and maintain geospatial databases that depict:

• transportation networks;
• flows of people, goods, vehicles, and craft over the networks; and
• social, economic, and environmental conditions that affect or are affected by the networks.

These databases are meant to support intermodal network analysis.
