ABSTRACT
This chapter discusses the performance of drivers with physical limitations was undertaken at the US The accident rate statistics document the increase in accident rates of older drivers and drivers with diminished capacities on a miles driven basis and indicate the need to study the performance of these drivers. A review of the transportation and human factors literature indicated that very little is known about the relationship of physical limitations and driving performance, therefore this area was selected for the study. Most of the human factors literature relating to older drivers has focused on the visual and cognitive aspects of driver behavior and performance. Specifically, the research addressed the behavior of drivers at T-intersections to determine the relationships between physical limitations as measured by range of movement of the head and neck, and visual field, and driving performance as measured by decision time.
