6. FTA Transit State of Good Repair Initiative • Steps in Developing a Transit Asset Management Plan • Inventory Assets and Data • Analyze Asset Conditions and Performance • Define Asset Investment Scenarios • Finalize Asset Investment Scenarios • Develop the Asset Management Plan • Objectives • Help public transit operators proactively maintain public transportation infrastructure in a state of good repair so that • they operate safely, efficiently, reliably, and sustainably, and • offer balanced transportation choices that help to improve mobility, reduce congestion, and • encourage economic development • Asset Management Lifecycle • Procure New Asset • Asset Delivery and Service Performance • Asset Condition Assessment • Asset Re-capitalization • Asset Management Plan • Outline how people, processes, and tools come together to address asset management policy and goals • Provide accountability and visibility for furthering understanding of leveraging asset management practices • Support planning, budgeting, and communications to internal and external stakeholders

7. What Role Does GIS Play in Asset Management • Asset Inventory vs. Asset Management • Asset Location vs. Asset Attributes • Asset Hierarchy vs. Location Hierarchy • GIS Centric Solution vs. System Integration within Enterprise IT Environment • GIS as Authoritative Source for Asset Location • GIS Integration with Enterprise Asset Management System

8. Asset Location Reference Model • Location Reference in GIS • Coordinate Reference: LAT/LON, Projected Coordinate System (State Plane Coordinates, UTM Coordinates, Local Coordinate System) • Address Reference: Address Geocoding • Spatial Feature Reference: Landmarks, Common Place Names, Existing GIS Features (Parcels, Bus Stops, Rail Stations, etc.) • Linear Reference: Location Referencing based on Linear Distance along Linear Features such as Bus Routes, Rail Tracks, etc. • Network Reference: Power Network, Drainage Network, ATC Network • Spatial Data Model for Location Referencing • Location Table and Representation Tables • Bridge Layer-based GIS data Model and Object-based Data Search Model • Facilitate Multi-methods of Asset Location Search

9. Asset Location Reference Model

10. Asset Location Reference Model • Standard Location Identifier as Common Key to Integrate with Enterprise Asset Management System • LocationID for Assets in Location Hierarchy • FACILITY-STATION Hierarchy: • e.g., A10-MZ(104)-RM(201) • FACILITY-YARD Hierarchy: • e.g., A99-BLD(A)-TPSS • FACILITY-WAYSIDE Hierarchy : • e.g., A12(WAY)-BLD(TCR-TPSS)-TPSS • LocationID for Assets Referenced by LRS (only) • ASSET CODE_ROUTE CODE_CHAIN MARKER (SIDE): • e.g., ETS_A1_319+58(1) • LocationID for Asset Referenced by Address (only)

11. GIS of Location Referencing Framework for Transit Emergency Exit at Track 2 282+60 Bridge from 277+90 to 281+75 Track 2 Track 1 Incident Happened at this location (chain marker 283+00) Platform from 275+78 to 281+75 Emergency Exit at Track 1 282+60 • Linear Events: • Bridge: location from 27790 ft to 28175 ft on Track line A1 & A2 • Platform: location from 27578 ft to 28175 ft on Track line A1 & A2 • Point Events: • Emergency Exit: location at 28260 ft on Track A1 & A2 • Incident: location at 28300 ft on Track A1 Linear Referencing System for Transit Network such as Track Network (Example is fictitious)

12. Development of Location Services in GIS • Purposes of Developing Location Services • SOA compliance • System integration with other business systems • Data sharing • Location Service Types • Data Services (Map Services) for Transit Asset Location Display and Query • Map display (require ArcGIS APIs) • Data Query (Rest end point style) • JSON (JavaScript Object Notation) formatted representation • RESTful (Representational State Transfer) Web Services for spatial functions • Spatial Search: e.g., • GP Process Services: e.g., • SOE (Server Object Extension) Services • SOE: custom built code to extend base functionality of ArcGIS Server by using ArcObjects • SOE service example: linear referencing service to locate a point/line event or asset along the LRS track • Hybrid Location Services • Location Services • Map Interface • Can be embedded within non-GIS application, or • Communicated through URL call

13. Development of Location Services in GIS

14. Development of Location Services in GIS SOE Service Example:

15. Development of Location GIS Portal for Asset Location Search • Asset Location Search Methods • Free Text Search • Hierarchy Search • LRS Search • Address Search • Mobile Version of GIS Asset Portal • Demo • Who will use it • Engineer • Repair Technician • Safety Inspector • First Responder/MTPD • Emergency Management Officer

16. GIS Integration with Maximo and Windchill • Common LocationID • Use Same LocationID • Embedded LocationID • Access Asset Attributes from GIS • Display Map from Maximo or Windchill • Challenges • Location Hierarchy Matching • Differentiate Location from Asset • Example: Rail Station is a location, also an Asset (Structure) • Example: Weez Bond is a location, also an Asset

17. Conclusion • GIS is the authoritative source for locations in Asset Management • Location Reference Model is the key to integrate GIS with Enterprise Asset Management System • Development of Location Services and GIS Location Portal facilitates integration of GIS with Enterprise Asset Management System • GIS is an essential component of the enterprise transit asset management system
