All data elements are structured and formatted according to predefined rules, with validation processes in place to confirm consistency and accuracy. The dataset has been reviewed to ensure all relevant friendly route name are included. The Idaho Transportation Department (ITD) implemented ArcGIS Roads and Highways in 2018, which is a Linear Referencing System (LRS) that manages road and highway data. It uses a data model with feature classes for routes, centerlines, and events to store and maintain roadway information, enabling accurate location management and analysis. The Idaho Transportation Department (ITD) first implemented a Linear Referencing System (LRS) for managing road data in the 1970s, which was a mainframe based system called the Milepoint and Coded Segment System (MACS System). In 2012, the LRS was migrated off the mainframe to Network Manager (NetMan). And finally in 2018, the LRS migrated to ArcGIS Roads and Highways. Editing stopped in NetMan in early 2017 for the migration to Roads and Highways, which is why the earliest "From Dates" on the data layers is 02/07/2017. 2017-02-07T00:00:00 1315 Enterprise Geodatabase Feature Class dataset EPSG 9.5.1(10.8.0) Simple FALSE 1315 TRUE FALSE Roads and Highways - Friendly Route Name Feature Class 1315 Road Network LRS Friendly Route Name Idaho Transportation Department OBJECTID OBJECTID OID 4 10 0 Internal feature number. Esri Sequential unique whole numbers that are automatically generated. RouteID Route ID String 12 0 0 The Route ID is created by the following in order: - 5 unique numbers - Designation of A (Ascending) or D (Descending) - Designation of IN (Interstate), US (United States Highway), SH (State Highway), OH (Off Highway), FD (Federal Route), or PO (Polygon/Political Boundary) - Highway number (i.e., 184, 093, etc.) or 000 for all other routes. Idaho Transportation Department String field representing the unique identifier. FromMeasure From Measure Double 8 38 8 Starting measure for the record along the road network. Idaho Transportation Department Double field representing the measure location. ToMeasure To Measure Double 8 38 8 Ending measure for the record along the road network. Idaho Transportation Department Double field representing the measure location. RoadCode Road Code String 200 0 0 Five digit number that represents the first five digits of the Route ID (i.e. 01500AIN015). This number is unique where each new segment added to the road network is the next number in the sequence. The exception to this is when a road has both ascending and descending sides (i.e. Interstate 15), then the five digit number will match for both segments. Idaho Transportation Department Number field representing the road code. Travelway Travel Way String 200 0 0 The direction of travel in reference to geometric measures, ascending (A) or descending (D). Idaho Transportation Department String field representing travel way. SystemCode System Code String 200 0 0 The system code is a 2-letter designation for the type of road, Interstate (IN), US Highway (US), or State Highway (SH). Idaho Transportation Department String field representing the system code. ICNO Interchange Number Integer 4 10 0 Shows the number associated with the interchange. Interchanges along interstates are assigned the closest milepost number to that interchange (all legs of the interchange have the same number). Idaho Transportation Department Number field representing the interchange number. CityAbbr City String 254 0 0 The name of the city the road is located within. Idaho Transportation Department String field representing the city name. SHSNumber State Highway System Number Integer 4 10 0 The highway number the segment belongs to. Idaho Transportation Department Whole number representing the highway number.

Idaho Transportation Department String field representing the abbr. route code. FriendlyRouteName Friendly Route Name String 200 0 0 Idaho Transportation Department String field representing the friendly route name. A combination of attributes from Roads and Highways layers to provide a more user-friendly road identifier as opposed to Route ID. This field information is fed in the Transportation Asset Management System (TAMS). - Main Routes : Route System Code + Route Number + Travel Direction + M - Connectors: Route System Code + Route Number + Travel Direction + C + City - Spurs / Business Loops: Route System Code + Route Number + Travel Direction + S or B + City - Ramps: Route System Code + Route Number + R + Exit Number + Cardinal Direction + On/Off Designation - Port of Entry (POE): Route System Code + Route Number + POE SegmentLengthMile Segment Length Mile Double 8 38 8 The route segment length in miles. Idaho Transportation Department Double field representing segment length. OnOffRamp On/Off Ramp String 5 0 0 Designates if the segment is leaving (Off) or entering (On) the highway. Idaho Transportation Department String field representing ramp type. CardinalDirection Cardinal Direction String 50 0 0 Designates the cardinal direction of the associated highway, North (N), South (S), East (E), or West (W).
