Abstract: An
impact between vehicle and roadside barrier is an extremely complex
event and it involves in problems of human, vehicle and road (barrier).
Based on analysis of factors that have influences on car impact with
highway barriers, a mathematic method of computer simulation is used to
develop car-barrier and occupant-car compartment impact models to study
such accidents on highway. A parameter study on dynamics of the car and
occupant and injury indices on occupant is carried out. According to the
results got previously, improvements for barrier design is presented so
as to reduce injury severity to occupant.
