  • 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


    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


    the effects

    of aging

    on d

    riving performance and behavior


    Focus groups were then held with two age groups of older drivers (55



    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


    ability to counteract the effects of aging, and older driver


    acceptance of them.



    vehicle systems that alert

    drivers to potential hazards (



    forward collision warning system) resulted in the highest safety rating while systems

    that facilitated a driver’s ability to control the vehicle (


    an a



    lock braking system) had the lowest safety rating.

    Overall, the younger age group


    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


    reliant on th

    e different systems compared to the 55


    64 year olds
