This study was conducted to investigate whether the driver or right front passenger is more likely to be injured in car crashes, and to examine possible factors affecting occupant injury. Two studies of frontal crashes were performed using the National Crash Severity Study (NCSS) data. The analyses were confined to unrestrained drivers who were not ejected. The first study considered only cars containing both a driver and a right front passenger. It is presumed that the crashes considered both of these occupants were subject to the same decleration forces, so that any differences in injury rates may be interpreted to be due to differences in occupant protection provided by the structure in front of different seating positions. The results of this first study indicated that right front passengers sustained higher levels of injury. In the second study, a logistic regression model made was applied utilizing variables such as occupant's age, sex, height, mass and seating position in addition to delta v (estimated change in vehicle velocity -- used to measure crash severity) and vehicle mass as explanatory variables. The major contributors to occupant injury were found to be delta v, age and sex. In contrast to the previous findings, the occupant's seating position did not enter into the model as a significant parameter. For both cases, sensitivity of the results was studied by narrowing the selection criteria. In conclusion, drivers were not more likely to be injured than were right front passengers, indeed the first study found that they were less likely to be injured. As delta v increases, the chance of sustaining higher level injury goes up; moreover, older occupants are more susceptible to higher level injury. Males are less likely than females to be injured in automobile crashes. (Author)
