Traffic accidents are a widespread global problem causing significant threats to human life and socioeconomic impacts. Traffic accidents are becoming more common due to the increase in population and the number of vehicles and therefore pose severe threats to human life. This study investigates the spatial and temporal characteristics of traffic accidents that occurred in Ankara between 2013 and 2020. In this context, the annual, monthly, daily, and hourly distribution of accidents were investigated to analyse the temporal characteristics of traffic accidents. In addition, Optimised Hot Spot Analysis was used to analyse the spatial characteristics, and Emerging Hot Spot Analysis was used to reveal spatiotemporal characteristics. The results reveal that the number of accidents increased until 2018 but showed a marked decrease in the last two years. It is emphasised that the decrease, especially in 2020, is closely related to the COVID-19 pandemic. In addition, there is an increase in the number of fatal accidents during the summer months, weekends, and night and morning hours. Traffic accidents and injuries are spatially clustered in the city centre, while fatal accidents are clustered not only in the city centre but also on the highways that provide access to the surrounding districts and provinces. The spatiotemporal distribution shows increasing trends with different hot spot patterns in these regions. The obtained results reveal that there are temporal and spatial patterns that vary according to the type of accident and traffic actors. This study guides local and national institutions in determining effective road safety policies to reduce traffic accidents in Ankara.
