Overview
Esri Roads and Highways
Esri’s LRS solution for DOTs

   Unifies existing DOT systems through a centralized LRS in the
   GIS, enabling data fusion and sharing across business units

      - Plan, manage, and maintain roadway LRS networks
      - Author maps that fuse data from different LRMs
      - Publish and share linear referenced data services

      rules can be applied to
      events.

  •   Events can have a different
      behavior for each type of

Temporality


•   Date ranges can be applied
    to LRS edits

•   Event measure updates
    reflect date ranges of LRS                 View After
    edits

•   Historical event measures
    that change due to LRS
    edits are “retired”

•   “Temporal View Date”
    enables data visualization
    and query for any moment     View Before
    in time

Data Model
Dynamic routes

    •   Dynamic routes are generated from centerline
        geometry and calibration point measures

  Centerline                                                  •   3 centerlines

                      The two routes above are derived
                         from three centerline lines

   •   Dynamic routes are generated from two feature
       classes and two tables

Bottom Line

  •   Roads and Highways requires data migration
      •   Migration approach requires modeling and ETL


  •   Understand the data model
