Road Type

The Idaho Transportation Department's (ITD) Roads and Highways Linear Referencing System (LRS) road type event polyline feature class distinguishes road segments based on road type, which can be a road, ramp, or port of entry/rest area. Roads are public thoroughfares or routes used primarily for the movement of traffic. Ramps are roads that allow vehicles to enter or exit a main road safely by providing space to change speed and navigate the change in elevation if necessary. Port of Entries within states are locations where a state enforces commercial vehicle regulations. Rest Areas are facilities for travelers to rest, often located every 50-100 miles along major roads, providing amenities like restrooms and picnic tables.
