Analysis of Relations Between Freeway Geometry and Traffic Characteristics on Traffic Accidents

Modelling traffic accidents on freeways is very significant due to the fact that accidents occurring on these roads are frequent and severe and cause traffic jams. Bearing this in mind, the objective of this paper was to analyze the impact of freeway geometry and traffic characteristics on the occurrence of traffic accidents with fatalities on freeways in Serbia. The paper analyzed traffic accidents with fatalities which had on the M-1 freeway with the total length of 394 km. A regression analysis was used in the analysis of data. The developed models represent the one of the first attempt of quantifying the mentioned impacts on the freeways in Serbia. These models should contribute to the improvement of safety of the existing freeways and designing new safer freeways.
