Abstract

On the basis of accident documentations GIDAS (German in-Depth-Accident-Study) the influence of different grip values between tires and road surfaces leading to an impact speed in accidents involving cars have been analyzed. The assumption is defined as influence of the braking grip value varying by ± 10 % for dry road surface situation and ± 15 % for wet on the real accident documentations for resulting injury severities of passengers and/or external traffic participants. The background of this study approach is oriented on better tires that could decrease the portion of most severe or fatal injured persons in road traffic accidents. It could be established an average by 2.0% on the reduction of most severe or fatal injured persons and a reduction of accidents with severe injured persons by 1.8% in average, if the grip value would be plus 10 respectively 15%. There would be an increase of the number of accidents with most severe or fatal injured persons by 2.0% and of accidents with severe injured persons by 7.0%, if the rip values would be reduced by minus 10 respectively 15%. The highest rates of reduction or increasing injury severity could be established for pedestrians and bicyclists.
