Spatial analysis of urban accidents using traffic police data (Case study: Urban accidents in Ardabil in 2016)

Traffic accidents are one of the leading causes of death and disability, causing an annual death of 1.23 million and tens of millions injured and injured worldwide. Meanwhile, a significant proportion of fatalities and injuries resulting from traffic accidents occur among urban accidents. According to the 2014 report of the Statistics Center of Iran, about 9% of accidents in the city lead to death and 60% lead to injuries. Therefore, due to the importance of this issue, patterns of urban accidents in the city of Ardabil were investigated using the GIS. The present study is a quantitative-analytical study. The data required for the study were extracted from the Ardabil Traffic Police as well as the municipal database and the Statistics Center of Iran. The map of Ardabil city areas was used to show the distribution of events. Nearest Neighborhood, Local Moran and Global Moran indices were used to determine the pattern of incident distribution, Medium Center Test was used to focus events, Ellipse Deviation test was used for distribution, and Kernel Density Test was used to identify the focus of the incident. Statistical analysis was performed using SPSS and ARC-GIS software. The results showed that the central part, northern and eastern suburbs of Ardabil are the most vulnerable areas of Ardabil in terms of intra-city traffic accidents. Intersections, squares and boulevards are the site of most traffic accidents that lead to the formation of accident hotspots
