  1. Managing a SHRP2 Naturalistic Driving Study in the Puget Sound RegionPresentation at the 2013 ITE-WA Annual Meeting & Conference John L. Campbell June 10, 2013

  2. Discussion Topics • Overview of the Naturalistic Driving Study (NDS) • Objectives • Test Sites • Overview of the Seattle Data Collection Site • Key Tasks • The Battelle Team • Recruitment Boundaries • Participant Pipeline • Recruit Schedule Install • Intake and Installation Process • Equipment Installed into Participant Vehicles • Progress to Date Recruit Schedule Install • Locations of Participants • DAS Installation & Total Intake Times • Benefits of the Study

  3. Overview of the NDS • Goals • Address the role of driver performance and behavior in traffic safety. • This includes developing an understanding of how the driver interacts with and adapts to the vehicle, traffic environment, roadway characteristics, traffic control devices, and the environment. • It also includes assessing the changes in collision risk associated with each of these factors and interactions. • This information will support the development of new and improved countermeasures with greater effectiveness. • Includes everyday driving data from ≈ 3000 drivers, male and female, 16 - 76+, for 1 or 2 years each

  4. Overview of the NDS • What types of data are being collected? • video images - 4 cameras (forward, rear, 2, in cab) • rates of acceleration, • lateral and vertical motion, • the presence of alcohol within the cabin, • position information, • turn signal actuation, • steering wheel angle, • speed, • seat belt use and air bag deployment • forward radar • Separately, data will also be collected on roadway elements such as road type, geometry, shoulders, safety furniture, signage, pavement markings, and more for the roads most frequently used by the volunteer drivers. • Crash investigations are also conducted

  5. 6 National Test Sites Selected sites include Tampa, Florida; central Indiana; Durham, North Carolina; Erie County, New York; central Pennsylvania, and Seattle, Washington.

  6. Seattle - Site Characteristics • Mix of urban and rural driving • High-density urban driving • Over 600 miles of rural roads • Many opportunities for driving in rural recreational areas • All within a relatively small geographic area • Mix of weather and terrain • Availability of advanced technologies in vehicles • High-quality GIS data available • Access to Pacific Northwest Gigapop for high-speed data transfer

  7. Seattle – Driver Characteristics • High population density • Diverse culture with a wide range of incomes, educational backgrounds, and ethnicities • Diversified economy employs a diverse workforce, from skilled labor to professional level • Aerospace, business and finance, import/export, software, Internet companies, biotechnology, biomedical research industries, etc. • Pro-research attitude (ready recruitment)

  8. Key Tasks • Obtain Required Institutional Review Board (IRB) Approvals • Prepare for Data Collection • Procure and prepare instrumentation facility • Train site staff • Schedulers, Assessors, Installers • Manage Participants • Traditional and call center recruiting efforts • Scheduling • Intake (consent, personal assessments) • On-going maintenance and any other issues • Install DAS in Participant Vehicles • Perform Crash Investigations • Upload Driving Data and Monitor Data Quality

  16. Head unit (as seen from passenger seat) • DAS (mounted under passenger shelf) • Front radar

  17. Participant Status (as of 5/31/13) Totals: Installed: 432, Completed: 206

  18. Location of Participants

  19. Benefits of the Study • Improved understanding of baseline driving behaviors: • Trip characteristics • Driver performance profiles • Adherence to laws and basic safety practices • Improved understanding of unsafe behaviors and traffic events: • Assess circumstances and motivations for speeding, red light running, etc. • Deconstruct crashes and near-misses and examine causality • How do driver, vehicle, roadway, and environmental factors influence behavior and impact crash risk? • Improved ability to develop safety countermeasures for: • Education and training • Roadway design and traffic engineering • Vehicle design • Regulation and enforcement • Ability to direct countermeasures at driver subgroups
