Spatiotemporal Analysis of Traffic Accidents Hotspots Based on Geospatial Techniques

Abstract: This paper aims to explore the spatiotemporal pattern of traffic accidents using five years of data between 2015 and 2019 for the Irbid Governorate, Jordan. The spatial pattern of traffic-accident hotspots and their temporal evolution were identified along the internal and arterial roads network in the study area using spatial autocorrelation (Global Moran I index) and local hotspot analysis (Getis–Ord Gi*) techniques within the GIS environment. The study showed a gradual increase in the reported traffic accid… Show more

“…The study conducted by Hazaymeh et al [29] investigated the temporal and spatial patterns of traffic accidents in Irbid Governorate over a period of five years, from 2015 to 2019, based on available data. The study utilized the Global Moran I index and hotspot analysis (Getis-Ord G i *) techniques in ArcGIS to identify the road accident hotspots.…”

“…Despite the fact that the aforementioned studies drew attention to clusters of road accidents, they did not conduct statistical significance tests to analyze their spatial distribution. In this context, very few studies have attempted to comprehend the spatial distribution of road accidents in Jordan, even though there is a great deal of accident data [28,29]. In many previous studies, road accident counts were frequently used to assess a position's safety issues [25,30,31].…”

“…The spatial distribution patterns of traffic accidents in the Al-Ahsa Region were identified using spatial autocorrelation (Global Moran's I). If the characteristics are spatially clustered, dispersed, or randomly distributed, it is shown by the values of Moran's I [84]. Equation ( 14) was used to calculate the Global Moran's I, z-score, and p-value using the spatial autocorrelation…”

“…where X i is an attribute value of the target feature at location i, N is the total number of features, W i,j is the spatial weight between features at locations i and j, and the neighboring feature at locations i and j has an attribute value of X j [84]. The results of Moran's I statistic can be verified using z scores, where a confidence level is established.…”

“…Finally, the presence of local spatial association was tested within the analysed data, for clustering geographically the hotspots, by applying the Getis-Ord Gi* statistic [31]. The Getis-Ord Gi* statistic is a tool of local spatial autocorrelation analysis, used in several contexts, such as cluster regions in the transportation equipment industry [32], forest fire management [33] active school travel (i.e., walking) clusters [34], industrial clusters [35], road accidents analysis [36,37].…”
