Topics

• Objectives of FOT

• Experimental design

• Data collection

• Challenges

3ITS America 2007 Annual Meeting June 6, 2007

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

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

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

International 8600 series

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

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

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
