Abstract:

Road traffic accidents are one of the most important global problems, which are considered a serious threat with their socio-economic and psychological consequences, as well as death and injuries. Therefore, handling spatiotemporal dimensions of road traffic accidents is necessary to determine the best and most consistent solutions to this problem. Recently, similar studies have been carried out based on Geographical Information Systems (GIS) techniques. This article is aimed to analyze the spatiotemporal distribution of road traffic accidents in Tekirdag province by using GIS techniques. For the last few decades, evaluating the spatial distribution of road traffic accidents in Tekirdag province, where traffic density has increased due to rapid population growth, urbanization, and industrialization movements, in a temporal process is important in terms of identifying and solving problems. Road traffic accident data from the General Directorate of Public Security and General Command of Gendarmerie were combined and analyzed with GIS techniques such as kernel density and hotspot analysis (Getis-Ord Gi*). As a result of the study, it was determined that 12.767 road traffic accidents occurred in Tekirdag province, which varied according to years. It has been determined that the accidents in the province mostly occur in some urban areas and main road routes. In addition, mapping using GIS techniques of study results will help traffic managers and decision makers in identifying priority locations to increase traffic safety. In this study, it is suggested to develop a dynamic database supported by GIS in which road traffic accidents are analyzed in spatiotemporal dimensions in order to implement traffic safety measures more effectively.
