The report documents an evaluation of driver characteristics and how they affect highway design and traffic operations standards. The study involved the identification of all standards which are a function of a driver characteristic; the development of a population profile for each characteristic; calculation of the sensitivity of each standard to realistic changes in a driver characteristic; and recommendation of changes to current specification values for driver characteristics and to standards. The report provides detailed examination of the driver characteristics perception-reaction time, driver eye height, vision, information processing capacity, age, sex, and pedestrian walking speed. The report recommends modifications to several design and operations standards which currently do not accurately depict the actions required of the driver in a particular situation or do not adequately compensate for the needs of the driving population.
