Use: For the querying and analysis of data (e.g., transportation performance management (TPM) metrics, Federal-aid project information, etc.) by the unique identification of a State’s urbanized areas, and generically by small urban or rural areas. Extent: All Public highways including ramps located within grade-separated interchanges as identified in 23 U.S.C. 101.a(27).

We also try to include all incorporated areas of the urban city, though an outlying island for the water plant or airport can be ignored if it has no classified roads. From there, we look for transportation assets to use as the UAB boundary. Census tracts give us jagged borders that cross and re-cross roads, as well as depend on ‘city limits’ and other imaginary boundaries that are too hard to find in the field. Where a segment of roadway is crossed by the Census boundary we will extend the UAB along that road to a cross-road, river bridge, railroad crossing, or other fixed asset. In the extreme, we might use a survey corner or extend a road alignment that doesn’t actually have an intersection but those are not ideal. We will also use rivers as they form a natural geographic barrier to urban spread. The ideal border road should be just beyond the commercial development; in keeping with the 5-10 year horizon of Functional Classification, as well as to avoid having equivalent commercial development on opposite sides of the street in distinct Character areas.
