Functional Classification

The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) functional classification event polyline feature class represents the functional classification of a roadway. This process is the recognition that individual roads and streets do not serve travel independently; rather, most travel involves movement through a network of roads. It becomes necessary then to determine how this travel can be channelized within the network in a logical and efficient manner. Functional classification carries with it expectations about roadway design, including its speed, capacity and relationship to existing and future land use development. Federal legislation uses functional classification in determining eligibility for funding under Federal Aid. This layer is an export from Roads and Highways that represents only the active records within the LRS. These are current “working” records.
