Abstract

The methodology that allows predicting the occurrence of traffic accidents on the motorway was studied and defined in this paper. On the basis of this assessment the implementation of active measures for reducing the probability of their actual occurrence is included. The intensity of traffic does not give a simple correlation with the number and the type of accidents, that relationship is more complex. Previous studies have been applied to motorways with six and more traffic lanes, and no studies have been carried out for four-lane motorways (with the driving and overtaking lane on one carriageway). This paper presents a new model for such motorways, the model is based on measuring values of parameters of traffic flow and external factors that affect the traffic flow. The degree of crash potential was brought to correlation with the existing statistical data on traffic accidents on the test section and traffic flow data. This model is important for experts to produce algorithms that manage variable message signs on highways.
