The document discusses recommendations for safer driver interaction with in-vehicle technologies based on research. It addresses methodology, design and engineering improvements, education and awareness efforts, and legislation and enforcement strategies. Recommendations include standardizing system designs, improving feedback and usability, educating drivers and dealers, considering restrictions on use, and integrating technologies into licensing and vehicle safety ratings. The goal is to maximize benefits and minimize risks of these evolving systems.

Final event – November 22, 2012 - Brussels 3

4. Methodology
• Single project with
– Focus group
– Questionnaire
– Naturalistic driving
– Observed driving
• Each provided evidence to support the
results of the other and strengthen the
research
Final event – November 22, 2012 - Brussels 4

5. Methodology
• Car types across nations
• Relative resources in set-up/analysis
• Allocation of collection/coding/analysis:
– Retain local data collection
– Recorded data submitted to single partner
– Partner responsible for all coding/analysis

Final event – November 22, 2012 - Brussels 6

7. Design and Engineering
• Standardisation of CC and SL design amongst
car brands and models.
• System functionality should be explained in a
more understandable and user-friendly way.
• Automatic detection of the legal speed limit to
inform CC/SL, possibly linked to NS
• Phase out CC/Standardise ACC?
• [Careful user-centred design is necessary for
reaching this objective]
Final event – November 22, 2012 - Brussels 7

8. Design and Engineering
• Clear, rapid (preferably non-visual) feedback
should be provided when speech inputs are
made to IVT
• Intuitive and logical use of IVT to reduce driver
distraction and workload, considering:
– Needs of the ageing population
 Size of displays
 Clarity/type of visual and audio information
 Comprehensibility of information
– Road/environment conditions
Final event – November 22, 2012 - Brussels 8

9. Design and Engineering
• Interface improvements for NS:
– Timely provision of guidance information, especially
roundabouts
– In-car volume adaptation
– Reinforce primacy of driving safely
– Whether it is nomadic or not, NS should be located
in a position that allows for an easy, rapid visual
perception of information
Final event – November 22, 2012 - Brussels 9

10. Design and Engineering
• Results suggest common user input to NS in
motion
• Systems give guidance on safe usage
• Could consider mandating prevention of
interaction while the vehicle is in motion?
Final event – November 22, 2012 - Brussels 10

11. Design and Engineering
• MP regarded as most difficult
• Better/stricter incorporation of handsfree
functionality to prevent the driver from
physically interacting with the MP.
• When receiving or making a phone call while
driving, an automatic message should be sent
to the inbound contact telling them that the
recipient is driving.
• Limit calls based on road/environment
complexity

Final event – November 22, 2012 - Brussels 12

13. Education and Awareness
• Awareness campaigns to highlight
situations in which IVTs should and
should not be used.
– To include suitability in different:
 Speed limit zones
 Traffic environments or driving conditions
(average speed of the traffic flow, traffic density
etc.)
 Weather conditions
Final event – November 22, 2012 - Brussels 13

14. Education and Awareness
• Car dealers:
– Responsibility to provide information to
buyers on appropriate use of IVTs
– Is it practical?
 2012 BMW 3-series – Owner’s manual PDF
• 325 × A4 pages (includes 6 pages on CC alone)
– In-built option for ‘user guidance mode’?
Final event – November 22, 2012 - Brussels 14

15. Education and Awareness
• The long term effects of the use on driver
behaviour, performance, and traffic
safety should be studied further.
– Need to collect more data to:
 Identify subsets of conditions when IVT use was
problematic
 Provide further evidence of causation

Final event – November 22, 2012 - Brussels 16

17. Legislation and Enforcement
• National/international laws on training,
licensing and use of IVT:
– Driver training to include the use of IVT
– Requires equipped cars to be available
– Allow learner drivers to:
 experience systems through learning process.
 get advice on how to use the systems safely.
Final event – November 22, 2012 - Brussels 17

18. Legislation and Enforcement
• Licensing/insurance hierarchy?
– Current:
Train in car Pass test in car Drive any car
without IVT without IVT with/without
(ADAS optional) (ADAS optional) IVT/ADAS

19. Legislation and Enforcement
• Licensing/insurance hierarchy?
– Future?:
– Better fit between training and vehicle
technologies
– …or manage through ‘black box’ insurance?
Final event – November 22, 2012 - Brussels 19

20. Legislation and Enforcement
• Greater integration of IVT/ADAS into
EuroNCAP star ratings
– Functionality
– Usability
– Nomadic devices – separate classification
• Must be based on robust research
findings…
