1. Understanding driver interactions
with In-Vehicle Technologies
Closing summary
Nick Reed (TRL)
INTERACTION Final Event
22 November 2012, Brussels

2. Summary of the project
• Broad study of driver behaviour with in-
vehicle technologies
• Overcome numerous challenges to
collect and analyse data
• Produced novel insights into driver
behaviour and IVT use – built on the
application of a range of techniques
Final event – November 22, 2012 - Brussels 2

• Andrew (TRL)/Patrice (Valeo)
Final event – November 22, 2012 - Brussels 5

6. Comparison to 100-car study
• 109 participants • 92 participants
• 100 cars instrumented – 80 • 30 cars – 3 from partners; 27 hired
participant owned; 20 from VTTI • 13 vehicle types
• Six vehicle types – 3 × Škoda
– 2 × (Ford; Toyota; Chevrolet) – 2 × (Vauxhall, Peugeot, Renault)
• 12 months data collection/vehicle – 1 × (Ford; Lancia; Citroën; VW)
• >40,000 hours of driving data • 4-6 weeks data collection/vehicle
• Purpose – study of pre-crash/near- • >3,000 hours of driving data
crash driving behaviour (with many • Purpose – study of interaction with
facets) in-vehicle technologies
• ~$100m • ~€2.5m

7. Comparison to 100-car study

8. Comparison to 100-car study
• Relative proportion of investment and
time
– Set-up (Heavy)
– Data collection (Light)
– Analysis (Heavy)
• Difficulties with car types over multiple
nations

9. Limitations
• Naturalistic driving data
– Associations between events – not causal links
– More data leads to higher confidence in
association but does not prove link
– Focus group, questionnaire, observed driving
techniques strengthen results
• Progress of technology
– Smartphones/Apps
– Integration of handsfree functionality
– Additional ADAS

10. Future prospects
• Radar data
• ‘Black box’ insurance policies
• Naturalistic data
– in-vehicle technology vs. odds ratios
• IVT
– Semi- and full-autonomy (ACC + LKAS = Super-
Cruise)
– HUDs; haptic displays
– Do these enable use of other IVTs?
Final event – November 22, 2012 - Brussels 10

11. Future prospects
• Interaction lives on!
• Exploitation beyond the life of the project
– Further studies planned by partners
– DAS systems can be re-used
– Database will eventually be publicly available
– Resource for researchers to interrogate to test
different hypotheses
Final event – November 22, 2012 - Brussels 11

12. We hope you enjoyed
today’s interaction!
