  1. Field Operational Test Planning Presented by: Dave LeBlanc UMTRI ITS America 2007 Annual Meeting & Exposition Palm Springs, CA June 6, 2007

  2. Topics • Objectives of FOT • Experimental design • Data collection • Challenges

  3. Objectives of FOT • Impacts on safety • Interactions during conflicts, near-crashes • Influences on driver behavior • Unintended consequences • Support safety benefits calculations by independent evaluator • Driver acceptance • Usability, satisfaction, willingness to purchase • Data archive of driving • “360 deg” sensor coverage

  4. 2007-8 Honda Accord EX Preliminary Experimental Design – Light Vehicle Platform • 108 drivers from southeast Michigan • 80 x 100 mile area • gender balance, 3 age groups • 16 vehicles ‘as their own’ • Nominal exposure: 6 weeks • 2 weeks baseline (IVBSS ‘silent’) • 4 weeks IVBSS enabled • 12 months, 275,000 miles • Exploring: targeting sub-populations &/or mixing in longer exposures to increase system exposure to near-crashes

  5. International 8600 series Preliminary Experimental Design – Heavy Vehicle Platform • Conway Freight (7,786 tractors; 30,449 trailers ) • Terminal in Romulus, MI (near Detroit metro airport) : • Line hauls • Local pickup/delivery • 15-20 drivers • 11 tractors (10 in field, 1 spare) • Long box, pup, double-pup trailers • 740,000 miles and 30,000 hours of driving

  6. Biographical & demographic data Onboard data Numerical Video Audio Offline-data Weather Roadway Crash data Pre-drive questionnaires Attitudes, behavior, style Post-drive questionnaires Focus groups FOT Data Archive Objective Data Subjective Data

  7. Onboard Data Collection • Continuous data from IVBSS system, vehicle, and FOT sensors* • 10 Hz to 50 Hz • Hundreds of data signals, plus: • 5 cameras with adaptive frame rates and compression • 7 radars (LV), 6 radars (HT) • Audio • Cell modem for remote monitoring * Sensors installed for analysis purposes but not used for IVBSS function0

  8. FOT sensors • Cameras: • Forward scene (may share with LDW) • Driver face • Over-shoulder • Left side (may share with LCM) • Right side (may share with LCM) • Cabin microphone • Differential GPS • Tri-axial accelerometer GPS receiver

  9. Monitoring Vehicles in the Field– Light Vehicle Platform Cell modem data automatically loaded every ~15 minutes into database to allow team to monitor fleet over the Web Individualdriver trips Automatichighlightsto assistreviewers

  10. Con-way Freight Romulus Terminal Re-distribution Center Maintenance Facility 200 ft Tractor Parking 400 ft 600 ft 10

  11. DAS data networking

  12. ConcludingRemarks • Accomplishments to Date: • Identified objectives of FOT experiment • Established scope of FOT • Secured trucking fleet partner • Developed onboard data system requirements • Developed network concepts and prototype for off-site data servers • Activities in 2007 • Complete experimental design • Complete prototype data collection systems • Complete preliminary subjective instrument design
