1 LRS Maintenance at Idaho Transportation Department Phil Hardy LRS Product Manager Brian Emmen GIS Manager

2 Idaho Transportation Dept. LRS History at ITD Mainframe-based attribute system (MACS) Functional class, federal aid #s, etc. Went into service in 1978 Paid for itself in 15 months dynamic segmentation Temporality / business rules GIS Esri since 1998 Asset Management Systems AgileAssets for Pavement, Maintenance, and Fleet Various other systems for Bridge, Safety, etc.

3 Idaho Transportation Dept. Room for improvement High mainframe maintenance costs No automated event location stability Integration by memo Bridge GIS MACS Safety Traffic

4 Idaho Transportation Dept. New system: Network Manager Handles both geometry and attributes Keeps them in sync Esri-based Task-specific interface Handles high-end LRS needs Easy to use Automated update of the entire enterprise Network Manager The devil is in the details

5 Network Manager LRS is simple except for things like: Multiple LRMs Concurrent Routes Event location stability Temporality Route anomalies Data maintenance Enterprise-wide integration

6 Multiple LRMs Event conversion Intelligent editing Shared fields State Cum. County Cum. RouteNum County StateBMP CountyBMP Length State Border Hays County Travis County Route 66 Route mi State Cumulative 7.8 mi County Cumulative

7 Concurrent Routes Handling weird configurations Reporting based on dominant route No double counting

8 Event Location Stability Before Event Location Stability After (basic LRS) Desired behavior

9 Network Manager Split Rules Don t split Split along Split across Split along & across Before Event LRS Rte Rte After Event LRS Rte Rte Rte Rte

10 Temporality Temporal Data Maintenance For both LRS & Events Sat Sun 2/2/2002 4/4/2004 Birth transaction: 1134 Birth transaction: 1569 Death transaction: 1569 Temporal Data Integrity Performance Transaction table ID: 1134 Date: 2/2/2002 ID: 1569 Date: 4/4/2004

11 Temporality Temporal Queries For both LRS & Events Temporal Event Conversion Ability to correct temporal mistakes

12 Route Anomalies Gaps Iron Mountain Road Loops Forks Heritage Harbor Drive Chestnut Ridge Circle Segment Codes: 1 for Circle 1 for Connectors Combinations Roundabouts Franklin Chase Terrace

14 LRS Data Maintenance Transaction & Event Effects Keeps a running audit trail of transactions (reports) Dates & Projects are associated with transactions Event Effects are associated with transactions Transactions can be rolled back, approved, disapproved Sample Transactions : Rename route Realign route Calibration Merge routes Delete route Reverse route Import geometry Split link Merge link Add link Delete link Reshape link Etc.

15 LRS Data Maintenance Projects Sat 2/2/2002 A collection of transactions Helps segregate multiple editors Just-in-time locking Can be selectively published Project A Project B

16 LRS Data Maintenance Quality control Locational ambiguities Null fields Sequencing/direction problems Geom/measure length ratios Measure gaps (warning only) Remembers allowed warnings Check each LRM, each subordinate route Check event tables Disallow version creation until QC is passed

17 Long term transaction LRS Data Maintenance Change Request Network Manager LRS Maintenance LRS QC Approve changes & publish new Version AgileAssets AMS Other Systems Process new Version: affected Event data are automatically updated Web services for getting latest LRS and updating Event data

18 LRS Web Services LRS export Network Manager with LRM and temporal options Event transform with LRM and temporal options Pull vs Push Fits into almost any workflow Simple web page Standalone app DB Integration

19 Network Manager LRS is simple even with things like: Multiple LRMs Concurrent Routes Event location stability Temporality Route anomalies Data maintenance Enterprise-wide integration

20 Idaho Transportation Dept. Where are we at now? Code complete as of the end of March Integration with AgileAssets asset management systems Testing Training What s next? Fully online by end of June 2012 Integrating other asset management systems via web services GIS-T 2013
