The Comparison between the Risk Perception of Drivers and Statistic Indicators of Traffic Safety in the Analysis of Effects of Reconstruction of Selected Urban Intersections

One of the basic criteria of the analysis of intersection reconstruction effects is the traffic safety criterion. Intersection traffic safety is determined by indirect indicators, like the number of conflict points, and direct indicators, like the number and severity of traffic accidents. In order to make the direct indicators of traffic safety comparable, they have to be analyzed in the context of the intersection traffic load before and after the reconstruction. The desired trend in the statistics of traffic accidents is, among other things, influenced by subjective experience of traffic participants about the traffic safety at an intersection. For the purposes of this study, a pilot testing of the subjective risk perception of safety of selected intersections, in the urban network of Osijek before and after a reconstruction, has been done on a random sample of drivers, by means of an anonymous questionnaire. Within the questionnaire, the socio-demographic features of drivers, education level, driving experience and the involvement in the traffic accidents (active and passive) were examined. The questionnaire encompasses the subjective perception of risks in the urban network of Osijek in general and at the selected intersections before and after the reconstruction. Perception of risks is segregated into an emotionally based risk perception (feeling of insecurity), assessment of probability of a traffic accident (with slighter and heavier consequences) and the concern about the personal safety and the safety of other traffic participants (with a special emphasis on children safety). Results gathered through questionnaire among drivers about their perception of the risks in selected intersections are compared to the direct (statistic) indicators of traffic safety in the selected intersections before and after the reconstruction.
