Improve the Quality of Travel?


TRB Session 644: Using VII Data, Part 1
Ben McKeever, US DOT, ITS Joint Program Office
January 16, 2008
    The Critical Need for VII

    In 2006 for the United States:
    • 2.6 million traffic crashes
    • 42,000 fatalities
    • 4.2 billion hours of travel delay
    • 2.9 billion gallons of wasted fuel
    • $80 billion cost of urban
      congestion

    Texas Transportation Institute, 2007

    Agenda


    •   Current state of traveler information
    •   What VII provides and enables
    •   Current VII activities related to traveler information
    •   Conclusion/next steps




3
    Traveler Information Today – The Good

    • Public sector progress
       – 511 widely deployed
       – 38% of freeway miles have
         detection (USDOT, 2006)
       – 56% of fixed route buses with
         AVL (USDOT, 2006)
    • Private sector progress
       – New technologies for collection
         and dissemination
       – Real time traffic and navigation
         more prominent
       – Consumer interest is growing
         and prices are dropping
    • Public-Private Partnerships are
      emerging
4
    Traveler Information Today – The Bad

    • Most metro areas still lacking
      quality traffic data
    • High O&M costs effect reliability of
      public sector data
       – As a result, data is not trusted
       – Inadequate funding for O&M
    • Real time data on arterials is
      almost non-existent
    • New technologies are slow to be
      deployed
    • Limited data/applications for other
      modes (e.g. transit, parking)

5
    VII Can Revolutionize Traveler Information

    • Complete network visibility
      (all roads, all modes)
    • Data Collection
      – low latency/real time
      – high granularity and
        reliability
    • Data Dissemination
      – Brings data into the vehicle
      – Can impact driver behavior
        en-route
      – Can optimize network
        performance

6
    Types of Data VII Can Provide

    • Anonymous “probe” messages from
      vehicle to infrastructure
      – Location, heading, speed, stop events,
        hard breaking events, weather
        conditions, vehicle diagnostics
      – 2-5% penetration rate needed for
        accurate data
      – Transit vehicles                            Weather Sensing

    • VII Advisory messages from
      infrastructure to vehicles
      – En-route alerts, travel times, dynamic
        routing, hazard warnings (e.g. icy road),
        parking info, transit arrival times or
        delays
7
    Types of Applications VII Can Enable


                             • Pre trip planning/routing for all
                               modes
                             • En-route routing around incidents
                             • Transit arrival times, advisories and
                               connection information
                             • “Killer Apps” from the private sector
                                – Off-board navigation using real time
                                  data on all roads
                                – Door-to-door driving times
                                – Real time map updates
                                – Parking availability/reservations



8
    Current VII Activities for Traveler Information


    • Michigan Development and Test Environment (DTE) and
      Data Use Analysis and Processing (DUAP)
    • VII California Testbed
    • New York ITS World Congress VII Demonstration




9
     Michigan DTE and DUAP


     • Michigan DTE supports testing of public and private sector
       traveler information applications
     • DUAP project demonstrates public sector uses of VII data
       –   Incident detection
       –   Travel advisories
       –   Road and weather conditions
       –   Winter maintenance
       –   Asset management




10
     VII California Testbed

                      • Leverages real world existing ITS for VII
                        demonstrations
                        – Integration of existing data sources with
                          VII probe data
                        – Complimentary uses of existing 511
                          system and VII
                        – VII tolling applications
                      • Congestion Initiative project will
                        demonstrate additional VII applications
                        – Dynamic pricing
                        – Parking Information
                        – Transit information to buses (tentative)


11
     New York ITS World Congress Demonstration and
     After

     • Demonstrate numerous VII applications (including probe data
       collection, travel advisories, travel times, tolling, etc.) in
       Manhattan and Long Island
     • Support for subsequent development of congestion-mitigation
       and road pricing related applications (post-World Congress)




12
     Conclusion

     • Current Traveler Information Systems are not adequately
       addressing the need for accurate, real time data on all roads
       and all modes
     • VII provides a wealth of data that could revolutionize the
       traveler information industry
     • VII enables numerous traveler information applications not
       currently available or mature
       –   Dynamic routing around incidents in real time
       –   Off-board navigation based on real time traffic conditions
       –   Door-to-door driving times with best alternative
       –   Multi-modal traveler information (transit arrival times and delays,
           parking availability/reservations)

13
     Next Steps


     • SafeTrip-21 and ITS World Congress Demonstration in 2008
     • Monitor results of POC testing of traveler information
       applications
     • Look for pre-VII early winners (e.g. I-95 Corridor Coalition
       probe data project)
     • Leverage Congestion Initiative projects in New York and San
       Francisco
     • Monitor cutting edge technology for VII and Traveler
       Information
