The attempt was made to investigate the influence of pavement width, horizontal curve radius, gradient, sight distance, curvature and traffic volume on accidents. The principal aim was to define the accident rate and accident cost rate. Factorial variations of types of accidents, day/night and dry/wet, were carried out for each parameter. In addition to nonlinear regression equations, multiple regression equations were utilized in order to take the simultaneous effects of interrelated functions of several parameters into consideration. Accident data and design parameters compiled from about 1150 km of two-lane rural highways in the Fed. Rep. of Germany were evaluated and analyzed. It was possible to confirm and quantify the fundamental relationships between highway and design parameters and accidents, already known from several papers on this subject, for two-lane highways in the Fed. Rep. of Germany. In addition, a wealth of new relevant details was obtained.
