  1. Introduction Oscar E. Jarquin Chief, Office of Information Technology California Department of Transportation (Caltrans) Los Angeles, California, USA • Civil Engineer • Land Surveyor • GIS Professional • Project Manager • Program Manager

  2. Governance and Structure • National Academy of Sciences • Transportation Research Board (TRB) • American Association of State Highway Transportation Officials • Technology Implementation Group (TIG)

  3. AASHTO Technology Implementation Group (TIG) FY 2007 – 2012 AASHTO TIG Focus Technologies Multi Level Linear Reference System (MLLRS)

  4. Lead States Team

  5. Iowa’s LRS Experience

  6. Agenda • What Iowa’s LRS includes • What do the DOT’s business units gain • What allowed Iowa to succed

  7. Implementation of NCHRP 20-27 model. Which separates business data from the location components of linear features (roads, navigable rivers, railroads, pipelines, etc.). Iowa’s LRS

  8. Base Record Inventory Project Data Program Crash PMIS Coordinate Route Reference Post Coordinate Route Milepoint Stationing Literal Description LRS Components Address Range Centerline Representation 1 Centerline Representation 2 Centerline Representation 3 NCHRP 20-27 Model

  9. LRS Components(all public roads 114,000 miles) • Cartography • Traveled Way Spatial • Roadway Spatial • Datum (Anchor Sections & Points) • Network (Transport Links & Nodes) • Routes • Parsed Names • Paths • LRM Components (ie Reference Post)

  10. Datum Transform Transform Transform Transformations between supported business location referencing methods (LRM) A common linear description of the network that can relate all the methods. LRM LRM LRM LRM LRM LRM

  11. How does LRS benefit the DOTImproved Accuracy • Entire road system (all public roads) are created based upon same standard • A separate abstraction layer call Roadway exist that provides a single representation of divided roadways • The system is represented over time (from 1/1/2001)

  12. How does LRS benefit the DOTCentral location of data • Route names for all roadway systems • One navigable network • Centerline for all roads • History of road network

  13. How does LRS benefit the DOTClearly defined rules and practices • LRM usage and results • Metadata for all LRS components

  14. LRS how did Iowa succeed • Reasons for creation of LRS • Division Level Sponsors • Business data kept separate from location

  15. California’s LRS Experience

  16. California Business Driver… Corridor Management

  23. AASHTO’s Technology Implementation Group – or TIG – scans the horizon for outstanding advancements in transportation technology and invests time and money to accelerate their adoption by agencies nationwide. Each year, TIG selects a highly valuable, but largely unrecognized procedure, process, software, device, or other innovation that has been adopted by at least one agency, is market ready and is available for use by other interested agencies.Guided by the vision of "a culture where rapid advancement and implementation of high payoff, innovative technologies is the expectation of the transportation community," TIG’s objective is to share information with AASHTO member agencies, local agencies, and their industry partners to improve the Nation’s transportation system.

  25. Many technical reports have been completed about developing and integrating a Linear Referencing System (LRS) within a state transportation agency. The magnitude of costs related to the development of a LRS and the commitment required by an agency can be overwhelming, especially if there are no data to support the costs or expected benefits. The Value Analysis (VA) Report will help the states by providing credible quantitative and qualitative benefits obtained from a s state’s investment as well as sample costs and requirements for implementing and maintaining a Multi-Level Linear Referencing System (MLLRS). The use of the word “baseline system” throughout the report represents the minimum requirement for a fully functioning MLLRS. The use of the term “optional functional elements” refers to supplemental elements that will improve the baseline MLLRS.

  26. Marketing Plan forLinear Referencing System • Assess LRS Needs and Contacts in Each State • Develop PowerPoint Presentation, Brochure and Posters • Develop Value Analysis Document (Contractor) • Develop and Host Webinar(s) • Give Presentation and/or Workshop at TRB, GIS-T and AASHTO IS Conferences • Visit States Offering Invitation • Assess LRS Level of Knowledge Transfer and Implementation Success • Final Report
