This dataset contains the Roads and Highways Road Network Linear Referencing System (LRS) Metropolitan Planning Organization (MPO) event polyline feature class that includes all roads within the road network. In Idaho, Metropolitan Planning Organizations (MPO) coordinate transportation planning in urbanized areas by working with local governments and the Idaho Transportation Department (ITD) to set regional priorities and manage federal transportation funding.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) Metropolitan Planning Organization (MPO) limits event polyline feature class is a linear representation of the MPO polygon layer. This layer is used within external applications that summarize data based on MPO boundaries but cannot utilize a polygon geometry, therefore utilize the linear features.</SPAN></P><P><SPAN>An MPO is a transportation policy-making and planning body with representatives of local, state, and federal government and transportation authorities. MPOs ensure that transportation planning in urban areas is developed cooperatively and guided by local and public input. MPOs work to balance the planning needs of local communities with the need for statewide connectivity, putting some of the planning process back in the hands of the locals.</SPAN></P><P><SPAN>Any area with 50,000+ population must have an MPO, Idaho currently has six: Kootenai MPO in Coeur d'Alene, Lewis-Clark Valley MPO in Lewiston (Asotin, WA), Community Planning Association of Southwest Idaho in Meridian, Magic Valley MPO in Twin Falls, Bannock Transportation Planning Organization in Pocatello, and Bonneville MPO in Idaho Falls.</SPAN></P><P><SPAN>MPOs receive funding through federal, state, and local sources for their operation. Federal transportation funds are channeled through state departments of transportation to the MPOs, but state and local government entities may also support MPO planning activities with matching grants, employee salaries and benefits, contract oversight, information technology services, and more.</SPAN></P></DIV></DIV></DIV>
The dataset follows established standards and conventions for logical consistency. 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 MPO limit features 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.
