In Network Screening - Segments, all routes in Georgia are subdivided into segments to make network screening easier. This allows you to compare smaller portions of a roadway with similar characteristics in Network Screening rather than evaluating an entire route.

Segment Criteria

When segmenting a route, a new segment is created each time one or more of the following roadway characteristics changes:

  1. Volume on the route (AADT, or Annual Average Daily Traffic)

  2. When a route changes between Urban and Rural

  3. When a route changes between Functional Classifications

  4. When the number of lanes changes on the route

  5. When a route changes between Ownership

  6. When a route changes between Speed Limits

Segment Lengths

Georgia DOT did not limit segment lengths.

  • The shortest segment is 0.0 miles

  • The longest segment is 12.31 miles.
