This project utilised three-dimensional computer simulation software (MADYMO, TNO, Netherlands) to investigate the effect of roadside crash barrier design on vehicle dynamics and risk of occupant injury. Rigid body models consisting of a vehicle (Ford Taurus) and a longitudinal roadside barrier (concrete barrier) were developed and used to simulate collisions at a range of impact angles. Acceleration data for the impact model was then used in a simulated sled test scenario. A 50%, male Hybrid III dummy was used to evaluate injury parameters. A comparison was made between traditional occupant injury criteria (HIC, apmax, chest acceleration, etc) and criteria derived to assess occupant injury in the evaluation of roadside barriers (THIV, PHD, ridedown acceleration, ASI, etc).
