How To Improve Lrs Maintenance

Transcription

1 GIS-T Conference 2015 Crossroads in the Heartland LRS Maintenance and Asset Management Systems Phil Hardy LRS Product Manager

2 Agenda Evolution of LRS Maintenance Lessons learned implementing Roads & Highways 1. Periodic vs dynamic updates 2. LRS editing with event updates in mind 3. Include Asset Managers into the QC process 4. Post-processing the LRS Interface GIS-T Conference

3 Evolution of LRS & Event Location Maintenance Historical Method Everybody s on their own (LRS & Events) LRS & Pavement LRS & Bridge LRS & Etc. GIS-T Conference

4 Evolution of LRS & Event Location Maintenance Historical Method Everybody s on their own (LRS & Events) Current Method in many DOTs Integration by memo Each group makes its own Event changes Pavement LRS Bridge Etc. GIS-T Conference

5 Single-Source LRS Great force multiplier 1 LRS edit makes many event edits across all systems Double-edged sword 1 LRS editing mistake means many event errors Automated Updates AgileAssets Transmetric Etc. GIS-T Conference

6 Lessons Learned Implementing Roads & Highways 1. Periodic vs dynamic updates 2. LRS editing with event updates in mind 3. Include Asset Managers into the QC process 4. Post-processing the LRS Interface GIS-T Conference

7 1. Periodic vs Dynamic Updates Dynamic The LRS is always the same as the source system ( internal events) Periodic Deliberate snapshots from the source system ( external events) GIS-T Conference

8 When to Use Dynamic Updates Roadway Inventory Functional classification Federal Aid # Jurisdiction Number of Lanes Lane widths Shoulder widths Median type Etc. GIS-T Conference

9 When to Use Periodic Updates Real Asset Management Pavement Bridge Safety Etc. Items that involve analytics Project package creation Scenario evaluation Works best in a stable environment GIS-T Conference

10 2. LRS Editing with Event Updates in Mind Remember you are not just editing the LRS you are editing EVERYBODY s events GIS-T Conference

11 Keeping the right perspective on LRS LRS GIS-T Conference 2015

12 Keeping the right perspective on LRS Asset Management Safety Congestion Pavement Bridges LRS GIS-T Conference 2015

13 3. Include Asset Managers in QC Suggested workflow No Roads & Highways LRS Editing LRS QC Pass LRS standards? Yes Agile Assets Run Test Interface Acceptable results? Yes Run Full Interface No GIS-T Conference

14 Change Reports GIS-T Conference

21 LRS Interface Methodology External System Esri Roads & Highways Bentley/Exor Various homegrown systems Integration Layer Custom for each external system Buffer Tables Allows prior review of changes LRS Gateway Common across the board AgileAssets AMS Home base for Asset events

22 LRS Editing with Assets in Mind 2 ways to do this edit Replace the entire route Do 2 realignments ~7 miles

23 LRS Editing with Assets in Mind 1) Replace the entire route Event effect: retire all events ~7 miles

24 LRS Editing with Assets in Mind 2) Do 2 realignments Event effect: retire only affected events ~7 miles

25 Involve Asset Managers in LRS QC Test Mode Option Allows business units to preview results Can preview changes to both LRS and Events Allows LRS to be reworked if necessary with no harm done GIS-T Conference

26 New Alignment Old Alignment

27 Interface to Roads & Highways GUI standard system job

28 LRS Interface Planning Make sure the 2 LRSs are in sync In terms of data In terms of LRM design Make sure your event location data is clean (i.e. it fits on the LRS) Make sure the 2 sides of the interface can fully communicate with each other

29 Configuration Steps Fill in Interface Config window (partially) Make connection (ArcCatalog - AgileAssets system) Register External Events with Rds & Hwys Create Rds & Hwys Export Network web service Create Rds & Hwys Relocate Events web services Finish filling in Interface Config window

41 Event Measure Behaviors Before Realignment Stay Put Move Snap Retire

42 Planning Make sure the 2 LRMs are in sync In terms of data In terms of LRM design LRM design needs to be based on lowest common denominator Examples: AgileAssets requires a base LRM that covers entire network R&H returns a single, concatenated route name for all LRMs Make sure the 2 sides of the interface can fully communicate with each other Make sure your event data is clean (i.e. it fits on the LRS)
