Abstract

The Swedish Road and Traffic Research Institute has previously developed a so-called prediction model for road traffic accidents referring to road links of ordinary two-lane roads. The model considers vehicle mileage, speed limit, class of alignment, and paved width. The purpose of the present study is to differentiate the model still further, primarily with regard to alignment. In addition an aim is to have the model consider season, light conditions, region and type of accident. The investigation refers to about 875 km of two-lane roads on the main road network in which some 14,000 single- or multi-vehicle accidents occurred during the period 1972-76.
