The number of crash-related fatalities in the United States climbed to over 35 thousand from 2014 to 2015, representing a 7.2% increase, and ending a 50-year trend of decline in this rate (NHTSA, 2016). The ability to drive safely represents an important activity of daily life that is closely tied to maintaining independence in old age (Persson, 1993), and with more older drivers logging more vehicle miles travelled than in previous cohorts, supporting safe driving in this age group is paramount. Advanced driver assistance systems (ADAS) are rapidly being introduced into new vehicles with each successive model year, and their incorporation into the driving task stands to bring many safety and convenience benefits to drivers of all ages. Despite the hope that the addition of more ADAS into the driving task leads to an additive safety benefit, previous research conducted in samples comprised largely of younger to middle-aged adult suggests otherwise. Also, safety benefits may not be realized if these vehicle technologies are not adopted, or if the incorporation of multiple systems leads to reductions in driving performance due to mode confusion, overreliance, or increased distraction. This dissertation provided a sample of older drivers (N = 101) experience with either a longitudinal warning system (Forward Collision Warning; FCW), a lateral warning system (Lane Departure Warning; LDW), or both systems over the course of a simulated drive to gauge effects on driving performance, as well as attitudes toward the system. Headway distance was not found to differ across groups, but drivers that received lateral warnings were found to show less deviation from lane center than drivers who did not receive lateral warnings. Attitudes toward these systems were found to be mostly positive prior to the simulated drive, and experience with the assigned system did not significantly alter these perceptions post-drive. / A Dissertation submitted to the Department of Psychology in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Fall Semester 2017. / December 13, 2017. / Aging, Forward Collision Warning, Human Factors, Lane Departure Warning, Transportation / Includes bibliographical references. / Neil Charness, Professor Directing Dissertation; Mark Horner, University Representative; Walter Boot, Committee Member; K.
