  • 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
