Abstract

This matched case-control study deals with the effect of the individual travelling speed on the risk of involvement in a road accident. The cases were cars involved in injury accidents dealt with within the framework of an in-depth accident investigation programme. The matched controls were cars passing the same road site as the crash-involved car, in the same conditions but without being involved in an accident. Only normal weather, daytime and free-flow conditions were considered. Overall, 52 cases and 817 controls were used. The speeds were obtained from kinematic reconstructions for the crash-involved cars, and using a laser speed gun for the controls. A significant positive relationship is found between the individual travelling speed and the risk of injury accident. Nevertheless, this study has limitations, due to the relatively small number of cases and to the data used (kinematic reconstructions always involve some degree of interpretation).
