A study carried out to investigate the distribution c braking time (reaction time plus accelerator-to-brake movement time, in ms) during real driving conditions at 60 km/hr gave the following summary information on the distribution of times (“A Field Study on Braking Responses During Driving,” Ergonomics, 1995:1903-1910):

mean = 535 median = 500 mode = 500 sd = 96 minimum = 220 maximum = 925 5th percentile = 400 10th percentile = 430 90th percentile = 640 95th percentile = 720
