In the US there exists a paucity of real world aligned mild crash data (delta-V<15 km/h), including the relationship between acute injury distribution and vehicular dynamics. This is particularly startling when US occupants in 2005 developed symptoms in approximately 272,000 “whiplash” (WAD) crashes resulting in a cost of $3.2 billion, exceeding the $2.4 billion in fatal rear crashes. This study aims to improve US real world mild rear aligned crash research by relating injury to vehicle dynamics.
