In Network Screening - Segments, all routes in Oklahoma 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. If the route changes between Functional Classifications

  4. When the number of lanes changes on the route

Segment Lengths

Oklahoma DOT did not limit segment lengths.

  • The shortest segment is 0.0 miles

  • The longest segment is 34.66 miles.
