KYTC - How Kentucky Roads are Segmented

In Network Screening - Segments, all routes in Kentucky are subdivided into segments based on roadway attributes. This allows you to compare smaller portions of a roadway with similar characteristics in Network Screening rather than evaluating an entire route.

KYTC’s segmentation attributes are dependent on the roadway type, provided below:

For a rural two-lane roadway, a new segment is created each time one or more of the following roadway characteristics change:

For an urban two-lane roadway, a new segment is created each time one or more of the following roadway characteristics change:

For a rural interstate/parkway roadway, a new segment is created each time one or more of the following roadway characteristics change:

For a rural urban/parkway roadway, a new segment is created each time one or more of the following roadway characteristics change:

For a rural multilane divided roadway, a new segment is created each time one or more of the following roadway characteristics change:

For a rural multilane divided roadway, a new segment is created each time one or more of the following roadway characteristics change:

For an urban multilane divided roadway, a new segment is created each time one or more of the following roadway characteristics change:

For an urban multilane undivided roadway, a new segment is created each time one or more of the following roadway characteristics change:

After segments are created following the guidelines above, minimum and maximum segment lengths are used to ensure that segments are not too small or too large.
