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

ITS America 2007 Annual Meeting June 6, Topics Objectives of FOT Experimental design Data collection Challenges

ITS America 2007 Annual Meeting June 6, 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

ITS America 2007 Annual Meeting June 6, 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 Honda Accord EX

ITS America 2007 Annual Meeting June 6, 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 drivers 11 tractors (10 in field, 1 spare) Long box, pup, double-pup trailers 740,000 miles and 30,000 hours of driving International 8600 series

ITS America 2007 Annual Meeting June 6, FOT Data Archive 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 Objective Data Subjective Data

ITS America 2007 Annual Meeting June 6, 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

ITS America 2007 Annual Meeting June 6, 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

ITS America 2007 Annual Meeting June 6, Monitoring Vehicles in the Field – Light Vehicle Platform Individual driver trips Cell modem data automatically loaded every ~15 minutes into database to allow team to monitor fleet over the Web Automatic highlights to assist reviewers

ITS America 2007 Annual Meeting June 6, Con-way Freight Romulus Terminal Maintenance Facility Re- distribution Center Tractor Parking 200 ft 400 ft 600 ft

ITS America 2007 Annual Meeting June 6, DAS data networking

ITS America 2007 Annual Meeting June 6, Concluding Remarks 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
