The effect of the geometric features of the road on traffic accidents

Abstract

In our developing country, as a result of the disruptions in both urban and intercity road planning and construction, there is a lack of function and irregular roads. The road structure that cannot meet the expected performance according to the service class it belongs to causes an increase in road operating costs and a decrease in traffic safety. In addition to the direct negative reflection of the effect of the defective road structure on the traffic, it also has a secondary negative effect as it causes stress on the drivers. Traffic safety should be the priority goal of decision-makers in the road planning and construction phase. In this study, the negative effects of road defects on traffic safety are mentioned. The data used includes the part of KGM arising from the geometric structure of the road in 2020. These data constitute 0,27% of the accidents.
