Washington Metro Area Transit Authority WMATA provides passenger transit rail, bus and paratransit services for DC and surrounding areas of MD and VA (1,500 sq mi). Rail: 117 mi track; 91 stations; 1,100 railcars; 217M annual ridership Bus: 11,000 stops; 350 routes; 1,480 buses; 124M annual ridership Paratransit: 600 vehicles; 2.4M annual ridership Infrastructure: Structures, track, power, signals, HVAC, drainage, IT networks, etc.

WMATA GIS Who we are: An IT Division within WMATA Enterprise IT Provides one consistent platform agency-wide for maps and data on WMATA’s infrastructure, transit service networks, and support services; Is WMATA’s sole and authoritative repository for geospatial information; Enforces spatial data consistency across other IT systems; A unique and critical component of WMATA’s overall IT architecture, and a critical resource for infrastructure asset management, service planning and analysis, incident management, and public information. Staff: 7 fulltime GIS professionals Software: ESRI suite of software with ArcGIS Server 10.2.2 and Oracle 12c, ArcGIS Desktop 10.2, 10.4.1, and number of extensions: Network Analyst, Spatial Analyst, 3D Analyst, GeoEvents, CityEngine, etc.

FTA Transit State of Good Repair Initiative 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 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

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

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

Asset Location Reference Model

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)

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)

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

Development of Location Services in GIS

Development of Location Services in GIS SOE Service Example:

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

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

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
