Abstract and keywords

Road departure crashes are one of the most dangerous crash modes in the USA. Lane departure warning (LDW) systems have been designed as an attempt to mitigate these crashes. Understanding the evasive manoeuvres employed by the driver is crucial to the development of an accurate model of a driver reacting to a LDW. Event data recorders (EDRs) were used to characterise recorded driver manoeuvres in road departure crash scenarios. Steering was the most common evasive action, followed by braking. On average, the evasive braking resulted in a deceleration of 0.41 g. Based on typical human reaction times to LDW, between 23% and 71% of crashes occurred before the driver could react and perform an evasive manoeuvre.
