This dataset contains the Roads and Highways Road Network Linear Referencing System (LRS) flow map node point event feature class where node locations represent a point of interest based off the flow line activity tracked within Idaho Transportation Department (ITD).
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) flow map node point event feature class identifies node locations that represent a point of interest based off the flow lines activity tracked within ITD.

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 flow map node 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.
