Vehicle crash can causes severe injuries to the occupant of the vehicle. These injuries can be measured. The injury measurement is intended to insure minimum safety levels
in severe crashes. There are several types of injury measurement such as ASI, HIC, THIV and TTI. This paper presents a numerical simulation of a light vehicle impacted to a curved roadside safety barrier and the ASI (Acceleration Severity Index)analysis of the occupant. The W-beam barrier and road model was developed using CAD software (Solidworks) and simulated
using FEA software LS-DYNA. Three crashes were performed with three types of velocities applied to the light vehicle. Based on the crashed that was performed the ASI value was calculated to evaluate injuries of the occupant. From the simulation it has been found that due the
higher velocities the ASI value also increases.
