ROAD TEST COMPARISON OF REACTION TIMES USING IN OPERATIONAL COMBINED BRAKE-ACCELERATOR PEDAL AND THE CONVENTIONAL BRAKE PEDAL

THE 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 SHOW THAT REACTION TIME USING THE COMBINED BRAKE-ACCELERATION PEDAL ARE FASTER BY 29.8%, THAN THOSE USING THE CONVENTIONAL SYSTEM. /AUTHOR/
