Abstract

Highway traffic accidents in general constitute a significant global issue, adversely affecting transportation, endangering life, and compromising the quality of life. To improve life quality, traffic accident types and regions should be analyzed in detail. The Geographical Information System (GIS) has been used as a valuable tool for addressing this challenge in recent years. By employing this approach, researchers can identify and visualize the locations where accidents are concentrated in a manner that is both comprehensive and readily comprehensible.
The objective of this study is to determine the regions within the Muratpaşa district of Antalya province that are at an increased risk of injury or fatality due to traffic accidents. Furthermore, the ages of the drivers involved in the accidents, the relationship between age and accident occurrence, the causes of the accidents and the distribution of accidents by year and month were examined by the way of statistics. For this aim, data obtained from the Turkish Republic General Directorate of Security for the years 2017-2021 were used. The Quantum Geographical Information Systems (QGIS) program was employed to determine the regions exhibiting elevated accident risk, and "Kernel Density Estimation" was used to categorize the accidents. A normality test was performed in SPSS to analyze the distribution of accidents by age. Accidents caused by rear-end collisions, failure to stop at red lights or stop signs, slowing or stopping in a disrupting traffic pattern, failure to slow at pedestrian and school crossings, or failure to yield to pedestrians were classified as traffic accidents caused by insufficient stopping visibility. In addition, traffic accidents caused by not following the rules of lane following and changing were considered as accidents caused by insufficient passing visibility. The study found that there was a significant risk of traffic accidents in three distinct regions within the Muratpaşa district. It was observed that individuals between the ages of 20 and 30 were predominantly involved in these incidents and that the main cause of these accidents was human errors made by the drivers. The overwhelming majority of traffic accidents (95%) resulted in injuries. The greatest number of traffic accidents was recorded in July.
