WebbInitial speed 60 km/h Reaction time 1.5 sec Rate of deceleration 10 m/s 2 metres travelled before car stops metres travelled before brakes are fully applied The physics that drive you Reaction time One reason for this increased risk is reaction time—the time it takes between a person perceiving a danger and reacting to it. Consider this example. WebbThe “reaction time” of the average automobile driver is about 0.7 s. (The reaction time, in this context, is the interval between the perception of a signal to stop and the application of the brakes.) If an automobile can slow down with an acceleration of 3 m/s2, compute the total distance covered in coming to a stop after a signal is ...
WebbPrediction of driver reaction to the lead vehicle motion based on the perception-reaction time (PRT) is critical for prediction of rear-end crash risk. This study determines PRT at various spacings in approaching and braking conditions, and examines the association of PRT and deceleration rate with crash risk.
