Road Mode

The Idaho Transportation Department's (ITD) Roads and Highways Linear Referencing System (LRS) road mode event polyline feature class identifies all road segments mode of travel. One-way roads carry traffic in only one direction. Interstates are divided roads with each direction of travel separated by a divider or median. The ascending direction of an interstate (in relation to the geometric measures) will have an ascending direction and the descending direction of a interstate (in relation to the geometric measures) will have a descending direction. Two-way roads carry traffic in two opposite directions, separated by a center line. Many state highways are undivided roads with no physical separation of travel. All two-way roads should have an ascending direction. This layer is an export from Roads and Highways that represents only the active records within the LRS.
