LRSID_Routes
The Louisiana Department of Transportation and Development’s (DOTD) LRSID_Routes dataset serves as the State’s official Linear Referencing System (LRS) for managing public roadway data, supporting transportation analysis, asset management, and federal reporting requirements including ARNOLD and HPMS submissions to the Federal Highway Administration (FHWA).
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>DOTD’s LRSID_Routes dataset is the foundational linear referencing framework used by Louisiana to identify, locate, and manage public roadway information across the State’s transportation network. The system assigns unique route identifiers and measure-based referencing that allow roadway characteristics, events, assets, and transportation data to be spatially aligned and consistently maintained over time. This network serves as Louisiana’s official contribution to the Federal Highway Administration’s All Roads Network of Linear Referenced Data (ARNOLD), which integrates all public roads into a standardized national framework. Using this linear referenced network, Louisiana annually develops and submits Highway Performance Monitoring System (HPMS) data to FHWA to support federal transportation planning, funding allocation, system performance analysis, and national roadway reporting requirements.</SPAN></P></DIV></DIV></DIV>

The GlobalID field within the Roads and Highways Linear Referencing System (LRS) is a system-managed, non-editable registry field that automatically assigns a unique 36-character Global Unique Identifier (GUID) to every feature or row entry. It ensures every center line, calibration point, route, and asset event maintains a single immutable identity across disparate geodatabases and non-GIS external systems; it is explicitly required by the platform to execute database replication, enterprise synchronization, and web-based transactional editing in the Event Editor; it serves as the primary key field used to preserve links to related tables or foreign key GUID fields when split, merge, or append editing operations occur on linear features.

LRS Network properties (https://doc.esri.com/en/arcgis-pro/latest/help/production/roads-highways/view-lrs-network-properties.html)
In Esri's Roads and Highways, the FromDate field is a temporal date-and-time attribute that defines the exact date and time when an LRS feature (such as a route, centerline, or event) officially became operational or active Together with the ToDate field, FromDate facilitates time awareness and time slicing. It dictates how geographic and attribute data are queried, edited, and visualized over time:

In Esri's Roads and Highways, the ToDate field is a temporal date-and-time attribute that defines the exact date and time when an LRS feature (such as a route, centerline, or event) officially ceased to be operational, active, or valid. The ToDate field acts as the closing boundary for a feature's lifecycle within the Linear Referencing System (LRS)

STATE MAINTAINED ROADS XXX-XX-F-LLL The RouteID for state maintained roads will be created from the existing five-digit Control Section number including a dash between the third and fourth digit (XXX-XX), a dash (-), followed by the one-digit Legacy Feature Type code (F), a dash (-), and a three-digit number representing the sequential occurrence of the feature (LLL). Note: All state maintained roads will have a twelve (12) character RouteID which will remain as a fixed identification number for each roadway segment as long as it remains a state maintained road. This RouteID includes the current control section number LADOTD employees are familiar with and limits possible confusion between control section numbers and Parish FIPS numbers used to identify non-state maintained roads. NON-STATE MAINTAINED ROADS PPPXNNNNNNTTTSFLLL The RouteID for non-state maintained roads will be created from the three-digit Parish FIPS number (PPP), the one-digit Prefix Code number (X), the six-digit Road Name Code number (NNNNNN), the three-digit Road Type Code number (TTT), the one-digit Suffix Code number (S), the one-digit Legacy Feature Type code (F), and a three-digit number representing the sequential occurrence of the feature (LLL). Discontinuous roadway segments of the same name within the same parish will be unique based on the sequential occurrence number. The Parish FIPS number is determined based on the physical location of the road. The Feature Type must be derived from codes provided in LA DOTD's GIS guidance document LADOTD_LRSID_Routes_RouteID_Format_2018.doc Note: All non-state maintained roads will have an eighteen (18) character RouteID which will remain as a fixed identification number for each roadway segment.
