  1. Shared CenterlineWorkshop October 24-25, 2012 Cassandra Isackson, PE Minnesota Department of Transportation Office of Transportation Data & Analysis

  2. “Create your future from your future, not your past.” Werner Erhard

  3. What’s Changed • Pave farm-to-market • Build interstates • Project Management We need information so we can build roads. • System largely built • Performance • Sustainability • Quality of life • Risk Management We need information so we can operate the system. Builders Owner/Operators

  4. Knowledge Management • People • Process • Technology

  5. Knowledge Management • People • Builders….Owner/Operators • Boomers retiring • Tech-savvy, smaller workforce (cellphones, etc.) • Process • Mix of old and new • Using complex information systems to manage complex transportation systems • Technology • Higher expectations • IT boom over last two decades • Moving toward real-time

  6. Overview • National data programs • TIS replacement project(s) • Data is an asset

  7. National Data • Highway Performance Monitoring System (HPMS) • Travel Monitoring and Analysis System (TMAS) • Vehicle Travel Reporting and Information System (VTRIS) • Motor Fuels • State and Local Finance • National Household Travel Survey (NHTS) • Tax Evasion • Motor Vehicles • Licensed Drivers • Certified Mileage • Toll Facilities

  8. MAP-21 • Performance Management • Asset Management • Enhanced National Highway System • National Bridge Inventory • National Freight Network • Truck Size & Weight Study • Condition and Performance Reports • Freight Condition and Performance • National Tunnel Inventory

  9. HPMS • Extent, condition, performance, use & operating characteristics of the Nation's highways. • Began in 1978. Replaced biennial condition studies from 1965. • Pre-requisite for approval of SPR (State Planning and Research) work program, i.e. Federal funds

  10. Biennial Conditions and Performance Report to Congress • An objective appraisal of the physical conditions, operational performance, and financing mechanisms of highways, bridges, and transit systems. • Used to develop authorization and appropriation legislation.

  11. HPMS deadlines • TIS Data Freeze: January 31st • AADT: May 1st • Sample Section (1,650 segments) data returned: May 1st • Certified Miles Report: June 1st • HPMS data upload to FHWA: June 15th • Route shapefile • Reference Catalog (NHS, STRAHNET, Truck Network) • Summaries Catalog (local roads, population, area, VMT) • Sections Catalog (63 data items)

  12. HPMS Data • All public roads • Length • Number of thru lanes • Paved/unpaved • Functional Class • AADT • Directionality (one-way, 2-way, divided)

  13. Certified Miles • Under the jurisdiction of a public authority: federal, state, county, town, township, tribe, municipal or other local government • Open to public travel • Passable by standard passenger cars • Open to general public use without restrictive gates, signs • Open at least 8 months of the year • Maintained including preservation of surfaces, shoulders, roadsides, structures, and traffic control devices

  14. Transportation Information System (TIS) • System of record • Existence of and jurisdiction over public roads • Physical roadway characteristics • System-level traffic volume • Crashes and safety characteristics • Pavement Characteristics • Reporting functions

  15. History • 1970’s Mainframe • Multifile updates all of the data within TIS when a route is redesignated or when mileage measures change (turn backs, construction projects, re-alignments, etc.) • Late 1990’s move some functionality into an Oracle database • Promising technologies delayed creation of multifile and reporting function outside of mainframe

  16. TIS Modernization • Current project: Linear Referencing System • Modernize ancillary systems • New traffic monitoring systems in implementation • Projects underway to move Crash and Pavement functionality into Oracle • Partnering with DPS to rebuild Crash system • Enterprise Asset Management System • Business Intelligence • State Aid Needs II

  17. MnDOT Data Principles • Data will be managed as state assets • Data quality will fit its purpose • Data will be accessible and shared as permitted • Data will include standard metadata • Data definitions will be consistently used • Data management is everybody’s responsibility • Data shall not be duplicated

  18. Two goals for data • User experience: • Accessing data is hassle-free and open access to public data is the norm. • Business Data Catalog, metadata, look and feel of technology • “Should not need training, should be intuitive” • “Should be a place where people want to be” • Stewardship: • Data are managed as state assets. • Business plans, quality control plan, performance metrics, cost of ownership

  19. “We can not do everything at once, but we can do something at once.” Calvin Coolidge
