Abstract

Accident avoidance by interference in the driver-vehicle loop by changing the vehicle is a specific area in the injury epidemiology field, not often studied in real life accident materials. Such factors can be i e improved handling, visibility etc. One of the most spread safety devices in this field is Anti Locking Brakes (ABS). Such braking system is intended to improve the maneuverability of the vehicle when braking. To which extent such systems are effective is only partly known.

In this study the effectiveness of ABS in the accident population is studied. By studying cars with and without ABS, but otherwise identical, it was possible to have a control group that was not affected by vehicle characteristics other than the braking system. Accidents were subdivided into those types more and less affected by the braking system as well as on road surfaces with different friction. Not only the occurence of the accidents werc studied, but also the severity.
