Özet:

The roads, which are the lifebloods of cities that resemble a living organism, are spatial systems that serve the transportation of vehicles and pedestrians. The condition of the roads, which is an essential function of transportation, can cause traffic accidents. In this respect, to minimize traffic accidents, the effect of environmental factors and the determination of the points where the accidents occur should be analyzed well. Because, due to traffic accidents, approximately 50 million people are injured, and 1.3 million people die in a year in the world. In this respect, various studies have been carried out to minimize traffic accidents in recent years. One of them is the analysis made with the help of Geographic Information Systems (GIS). By recording spatial data with GIS, black spots where accidents occur frequently are determined, environmental factors and potential situations of those involved in the accident can be analyzed. In this study, the traffic accidents that occurred in Üsküdar district were discussed, the traffic accident reports obtained from the Istanbul Traffic Inspection Branch Office, and the environmental factors causing the accident were evaluated. In this context, the black spots where accidents frequently occurred between the years 2016-2020 were mapped with the ArcGIS 10.8 program, road surfaces, the education levels of the drivers involved in the accident were interpreted, and the areas with high accident risk and their causes were tried to be determined. It has been determined that a significant part of the accidents occur at 15 July Martyrs Bridge entrance, Altunizade Junction and Pasha Limani Street due to the carelessness of the drivers and the intersections.
