  1. July 14, 2011 Esri Highway Data Maintenance Solutions: An Introduction Adrien Litton Majunu Seran

  2. Overview of Highway Data

  3. Multiple datasets across multiple agencies • Pavement • Maintenance • Traffic • Safety • Signs • Freight • Snowplowing • Etc.

  4. Esri Road and Highways Solution Highway Engineers Applications Multiple Clients Web Multiple Users Mobile Workflows Desktop Maps & Reports LRS Field Crews Planning Maintenance We’re changing the way we think about highway data Multiple Systems GIS Analysts Pavement Management Assets Management Traffic Safety

  5. Roads and Highways Data Model

  6. Data Model • Based on Esri Roads & Highways model • Supports Advanced Linear Referencing • Multiple LRMs • Dynamic Features • Location Management • History • Extends to client data requirements • Loosely coupled with business data

  7. Roads and Highways Data Model

  8. Introduction to Linear Referencing Systems

  9. What is LRS? • Method for locating assets along linear facilities • Distinguishes position from location • Position represents an XY coordinate on a map • Location represents a distance along a linear feature • Most highway departments’ method of choice for managing asset data

  10. Highway data is managed using linear referencing • A route reference and a measure value

  11. Highway data is managed using linear referencing • A route reference and a measure value • One measure creates point events • Two measures create line events

  12. Highway data is managed using linear referencing • A route reference and a measure value • One measure creates point events • Two measures create line events • Allows non-spatial data to be overlaid for advanced analysis A one-dimensional location system

  13. Highway data is managed using linear referencing • A route reference and a measure value • One measure creates point events, two measures line events • Allows non-spatial data to be overlaid for advanced analysis A one-dimensional location system

  14. Advanced Linear Referencing Systems

  15. Advanced Linear Referencing • Multiple Linear Referencing Methods • Dynamic Route Representations • Time Aware LRS • Rule-based Event Behavior By making LRS more robust we make highway data more interoperable

  16. Multiple Linear Referencing Methods

  17. Multiple Linear Referencing Methods • Reference Markers • Project Stationing • Mile Posts • Road Inventory LRMs are like map projections; users need to be able to translate seamlessly from one to another

  18. Traditional approaches to multiple LRMs LRM 2 LRM 3 LRM 1 • Multiple Route Geometries • Transformed Measures in Event Tables • Reference Datum LRS LRS LRS Our solution is closer to the Reference Datum approach

  19. Dynamic Route Representations

  20. Dynamic Route Representations • Routes are defined in the data model • Dynamic routes are real features that are managed as tabular data • Dynamic route live in the map Different users have different definitions of a route

  21. Time Aware LRS

  22. Time Aware LRS • Present – We need to see the current state of our highways • Past – We need to see what our highways looked like when incidents occurred • Future – We need the ability to add planned highways to our data By capturing time we add a whole new dimension to highway data

  23. Location Management

  24. Esri Roads and Highways manages location Four possible things that happen to events.

  25. Esri Roads and Highways manages location The event moves (preserves location)

  26. Esri Roads and Highways manages location The event moves The event stays put (preserves position)

  27. Esri Roads and Highways manages location The event moves The event stays put The event goes away (preserves both location and position)

  28. Esri Roads and Highways manages location The event moves The event stays put The event goes away The snaps to another route (preserves proportion)

  29. Esri Roads and Highways manages location Events are configured based on the type of work being performed By updating events based on maintenance activities you control the LRS rather than react to it

  30. Configuring the ALRS

  31. Managing Workflow

  32. What is a Workflow? Projects Web Activities Tasks Mobile Desktop

  33. Esri Roads and Highways Workflow Create a Project Publish Data Add a Redline Update Network Verify Results Road Inventory User Road Inventory User Linear Network Maintainer QA/QC Staff GIS Supervisor

  34. Editing and Validating Data

  35. Summary

  36. Summary • Esri Roads and Highways is a world class highway data management solution • Supports Advanced Linear Referencing • Workflow driven • Easy to use editing tools • Incorporates data validation • Scheduled for release Q4 2011
