If Speed of a Vehicle Known, Can We Determine Forces on Occupants?
Posted: Fri Mar 03, 2017 8:38 am
Q: (rcd via email) If we know the speed of the vehicle at the time of the accident , type of the vehicle(Toyota etc..) can we determine the estimated force on a patient or driver to determine the extent of injury after a car accident?
A: Speed of a vehicle generally does not tell you anything about possibility of an injury since a car at 100 mph can simply coast to a stop position. Impact Speed change or DeltaV is generally used to characterize the exposure in a collision event. It can also help determine the possibility of an injury in a collision.
NHTSA (CIREN and other projects) and other research organizations look at impact speed change in collisions vs occupant injuries to characterize and categorize the possible injuries which have occurred and therefore can occur at various impact types and DeltaV levels.
