In Network Screening - Segments, all routes in Texas 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.

Volume on the route (AADT, or Annual Average Daily Traffic)
When a route changes between Urban and Rural
When a route changes between Functional Classification
When the number of lanes changes on the route
