Abstract
This experiment was conducted to compare road test
reaction times obtained from a dual-function pedal that was
completely integrated into an automobile's accelerating and
braking systems.
The resultant mean reaction times, measured from seventeen
subjects in tests at Laguna Seca Raceway, Monterey,
California, were 0.316 seconds for the dual-function pedal
and 0.450 seconds for the conventional brake pedal. Analysis
of variance showed that the reaction time when using
the dual-function pedal was significantly faster than
reaction time when using the conventional pedal at the p = .01
level. The results of this experiment show that reaction
times using the combined brake-accelerator pedal are faster
by 29.8% (corresponding to reducing the stopping distance
by 12 feet at 60 miles per hour) , than those using the conventional
system.
