|dc.description.abstract||The nature of foot movement time (MT) in an actual braking maneuver and in a stationary vehicle was investigated regarding the effects of age and gender of the driver and nature of the stimulus to which the driver was responding. ANOVAs showed that the nature of the stimulus was not a significant factor in length of MT, but distance between pedals and age-gender levels were found to have significant effects. For the actual braking maneuver, gender and the gender-by-age interaction were significant; in the stationary vehicle portion of the study, they were not. Mean foot MT for both genders over all conditions were 0.28 seconds for women and 0.22 seconds for men. For older drivers, over all conditions, the mean foot MT was 0.25 seconds, and, for the younger drivers, 0.24 seconds. Linear regressions revealed high intra-subject variation in MT, which was corroborated by comparing with data from other parts of the study. Poor r2 values for fitting the data to Fitts' Law and to a modification of Fitts' Law were attributed to this high intra-subject variation and to obtaining data from only two different movement amplitudes. It was found that drivers' foot MTs tended to converge to a common value when controlling the vehicle at 88 km/hr (55 mph) as opposed to sitting in the driver's seat while the vehicle was stationary; mean foot MT for each subject group decreased, and differences between genders and age groups significantly diminished while the car was in motion.||en|
