“…The k-means algorithm employs accident frequency counts as parameters for the clustering of these locations. However, the studies of [14,16,20] show that density-based clustering algorithms and spatial analyses outperform the k-means algorithm when applied to determine accident hotspot locations. The authors of [21] applied k-means to group the combinations of the four indicators into categories with homogeneous effects on run-off-road injury crashes frequency and severity.…”

“…In addition, these both algorithms are unable to process categorical data [7,12]. Moreover, the k-means algorithm takes into account the complete dataset and produces clusters with spherical shapes, which may not be ideal for accurately depicting regions prone to traffic accidents [20]. The authors of [7] applied the k-means method to identify highfrequency accident areas.…”
