• Abstract:
  Older drivers make up the fastest growing
  
  segment of the
  
  driving population and are
  
  ,
  
  in general, unde
  
  rrepresented in
  
  vehicle crashes due to their self
  
  -
  
  restrictive driving habits.
  
  However, as the baby
  
  -
  
  boomer generation
  
  ages into the
  
  population of older drivers, the presence of in
  
  -
  
  vehicle systems designed to counteract the physical and psychological
  
  changes
  
  of aging could change their habits.
  
  Using a literature review to identify systems, effects of aging, and crash
  
  statistics of older drivers
  
  ,
  
  various in
  
  -
  
  vehicle system types were identified and rated for their potential to
  
  mitigate
  
  the effects
  
  of aging
  
  on d
  
  riving performance and behavior
  
  .
  
  Focus groups were then held with two age groups of older drivers (55
  
  -
  
  64
  
  and 65
  
  -
  
  75) to assess their acceptance of four different systems identified by the literature review.
  
  Data from the focus
  
  groups were factored into a fi
  
  nal in
  
  -
  
  vehicle system matrix that rates system types’ benefits to older drivers based on their
  
  generalized
  
  ability to counteract the effects of aging, and older driver
  
  s’
  
  acceptance of them.
  
  In
  
  -
  
  vehicle systems that alert
  
  drivers to potential hazards (
  
  e.g.,
  
  a
  
  forward collision warning system) resulted in the highest safety rating while systems
  
  that facilitated a driver’s ability to control the vehicle (
  
  e.g.,
  
  an a
  
  nti
  
  -
  
  lock braking system) had the lowest safety rating.
  
  Overall, the younger age group
  
  s
  
  of older dr
  
  ivers were more trusting of the various safety systems and felt that drivers their
  
  age would want the various systems
  
  compared to the older age group.
  
  In contrast, the 65
  
  -
  
  75 year olds were less anxious
  
  and less concerned about becoming over
  
  ly
  
  reliant on th
  
  e different systems compared to the 55
  
  -
  
  64 year olds
