| Abstract Research suggests that driver safety is reduced by driver fatigue, risk-taking and inappropriate driver behaviour. These effects can be combined to produce a single strong predictor. The present study examined whether this approach was sensitive enough to detect effects in a small sample (N = 103) who had a low annual mileage (about 5000 miles). The study identified correlated attributes of the main predictors and examined whether these added to the model. The results confirmed the predictive power of driver fatigue, risk-taking and inappropriate driver behaviour. They also showed that the effects of other correlated variables did not add to the predictive power of the model. Other important features of the approach included the development and use of short measuring instruments, adjustment for the social desirability bias and use of an outcome measure combining road traffic collisions and near misses. |
