Infrastructure Management Location Referencing Management System Project LRMS Infrastructure Management Regional Presentations 1. LRMS Background

LRMS Infrastructure Management Regional Presentations Project Beginnings 1996 Common Highway Location Referencing –SISP Vol.2 Issue 2, October 1996 The Referencing System Must: Provide a recognisable field location system for contractors, consultants, LTSA, Police etc. be compatible with current (and developing) database technology used by Transit be a quality controlled system with high integrity meet timeliness requirements be able to handle complex motorway environment manage databases by internal processes

LRMS Infrastructure Management Regional Presentations Objectives of LRMS “To specify consistent and accurate methods of location referencing, supported by quality systems with timely and appropriate office and field procedures, to provide accurate and consistent referencing on the State Highway network over time.” Catalyst IT Report

LRMS Infrastructure Management Regional Presentations Project Framework Location Referencing Methodology and Procedures LRS Where are we? LRMS The Foundation for Managing the New LRS Management of LRS

LRMS Infrastructure Management Regional Presentations LRMS tells us Where we Are A single location can have a number of references depending on the LRS Method adopted

LRMS Infrastructure Management Regional Presentations Transit Information Hub TMS PROMAN RAMMEtc. Data Database Application Communication User Interface Oracle: Network Model (Based upon LRS) GIS exor Highways exor Highways will become the Referencing Platform Project Vision: “LRMS will be the Integrator for Transit’s asset information systems and will be the Hub for the Road Information Management System” - Dave Robertson

LRMS Infrastructure Management Regional Presentations Benefits from LRMS Project Enhanced Location Referencing Methods Improved business practices Quality assured processes Timeliness of recorded changes to the network information Better understanding by the users A core database for Location Reference Information for all Transit Systems Spatial representation of the Highway Network

Infrastructure Management Location Referencing Management System Project LRMS Infrastructure Management Regional Presentations 2. Project Overview

LRMS Infrastructure Management Regional Presentations A Lot has been Happening Behind the Scenes Much of the project development will not be seen by the general practitioners LRMS Workshop LRMS

Infrastructure Management Regional Presentations Progress is on Schedule 100% 98% 60% 10% Key Milestones Reached –Reviewed existing LRMS and proposed new system (Field and Data Model) –Reviewed Business Processes and identified improvement opportunities –Developed interface methodology

LRMS Infrastructure Management Regional Presentations Project Deliverables Include Task 2000 –Business Process Analysis Task 2100 (draft) –Principles of Location Referencing Task 2200 (draft) –Spatial Referencing Requirements Task 2300 (draft) –Location Referencing Requirements in Transit Task 2400 (draft) –Highways by Exor Gap Analysis Task 2500 (draft) –Implementation Strategy for LRMS

Infrastructure Management Location Referencing Management System Project LRMS Infrastructure Management Regional Presentations 3. Changes to Field Signage

LRMS Infrastructure Management Regional Presentations Existing Field Signs 1. Reference Stations (RS) –Benchmarks along highway –Start of displacement measurements –Established at: Region Boundaries SH Intersections Approximately 16km intervals

LRMS Infrastructure Management Regional Presentations Existing Field Signs 2. Established Route Position (ERP) –Intermediate Benchmarks –Installed to  0.1% –Established at: Ramps Dual or Divided Carriageways Approximately 3-5km intervals

LRMS Infrastructure Management Regional Presentations Existing Field Signs 3. Route Position Marker (RPM) –Intermediate Reference “flags” –Also called km markers –Installed to  100m –Established at: 1km offsets from RS

LRMS Infrastructure Management Regional Presentations Existing Field Signs 4. Bridge Position Marker (BPM) –Unique bridge reference –Sign displays bridge position to 10m –Established at both ends of bridge –Can double as ERP (letters ERP included below number)

LRMS Infrastructure Management Regional Presentations Other Aspects Ramps also marked with ERPs Roundabouts not treated as separate roads OFF RAMP

LRMS Infrastructure Management Regional Presentations What is Changing (Summary)? Signs meant for distance referencing will –Have a green marker band –Have clearly marked distances to two decimals (10 m) KM Markers will be used as ‘flags’, not for accurate referencing Bridges will be referenced differently

LRMS Infrastructure Management Regional Presentations New Signage 1. Reference Stations (RS) –Remain Unchanged –“I” and “D” added for dual carriageways OFF RAMP

LRMS Infrastructure Management Regional Presentations New Signage 2. Kilometre Markers –Install on separate post to edge marker –Include SH shield –Not used for referencing (+/- 100m “flags”) –Remove green band OFF RAMP

LRMS Infrastructure Management Regional Presentations New Signage 3. Established Route Position (ERP) –Install new signs at exact km (3-5) existing sign positioning phased out –Displacements from distance marked on sign (e.g. 3.00km) –Add green “referencing” band Retrofit existing OFF RAMP

LRMS Infrastructure Management Regional Presentations New Signage 4. Ramp Identification –Introduce Interchange numbering –Ramps given unique reference –Displacements from 0m at signs –Include green “referencing” band –Include SH shield OFF RAMP

LRMS Infrastructure Management Regional Presentations New Signage OFF RAMP 5. Bridge Identification –Bridges given unique reference –Reference will not change –No link to LRS RAPID system used to create ID

LRMS Infrastructure Management Regional Presentations New Signage OFF RAMP 6. Roundabout Identification –Roundabouts are separate roads with break in main road referencing –Signs same function as Ramp identifiers –Displacements from 0m at sign –Roundabouts treated as separate roads Many TLA’s reference this way

LRMS Infrastructure Management Regional Presentations Distance Breaks SH SH1 SH1 and SH3 SH Distance Break

LRMS Infrastructure Management Regional Presentations Summary of Principles All location referencing (LRS) signs have green bands KM Markers are only reference “flags” and not to be used for measurement Only LRS signs have distances Further Information in Task 2300 Report OFF RAMP

Infrastructure Management Location Referencing Management System Project LRMS Infrastructure Management Regional Presentations 4. Interfacing with RAMM

LRMS Infrastructure Management Regional Presentations Multiple IT Platforms Requiring Location Referencing These are used to support its business, for example: –RAMM (Road Asset Maintenance Management) –dTIMS (Multi-year Programming and Optimisation) –LAR (Local Access Roads) –NOMAD (Forward Works Programming) –TOPS (Overweight Permits) –PROMAN (Project Management) –TMS (Traffic Monitoring Information System)

LRMS Infrastructure Management Regional Presentations Highways by Exor Being Implemented for: –Ability to manage the network over time (i.e. roll back the clock) –Ability to better manage underlying inventory when changes to the network –Seamless Spatial and Linear referencing methods

LRMS Infrastructure Management Regional Presentations Transit’s “Vision” is for an Enterprise Data Environment

LRMS Infrastructure Management Regional Presentations Existing Information Transfers Between Applications

LRMS Infrastructure Management Regional Presentations RAMM Database Network Environment

LRMS Infrastructure Management Regional Presentations Hub Concept for Interfacing

LRMS Infrastructure Management Regional Presentations New Implementation Architecture

LRMS Infrastructure Management Regional Presentations Implications of Hub Users will be able to access LRMS data through other applications Plan to make data model open and available to enable different applications to use LRMS data

Infrastructure Management Location Referencing Management System Project LRMS Infrastructure Management Regional Presentations 5. Spatial Data

LRMS Infrastructure Management Regional Presentations Spatial Data Project undertook assessment of role of spatial data in Transit Recommended that: –Existing linear referencing system be maintained as primary reference –Only those data most suited to spatial referencing shall be spatially referenced Reference stations and other key referencing features Road centreline Bridges Off-road objects such as signs

LRMS Infrastructure Management Regional Presentations Multiple Reference Systems GIS can have several ‘layers’ reflecting different ways of referencing LRMS will form foundation for all referencing Local road names and references can be linked to LRMS with spatial referencing

LRMS Infrastructure Management Regional Presentations Transit’s Centreline Captured in kinematic GPS surveys by WDM Two years of data available; third survey just started 2000 survey evaluated for Wellington network Estimated that 95% of data suitable for LRMS with little corrections
