Road Accident Hotspots on Jordan’s Highway Based on Geometric Designs Using Structural Equation Modeling

One of the primary objectives transportation engineering is to increase safety road infrastructure. This study seeks determine relationship between geometric design parameters in relation accident criteria based on hotspots Jordan’s Desert Highway. The data (from 2016 2019) were collected from Jordan Traffic Department. spatial pattern was identified using a GIS tool named Getis-Ord Gi* severity index accidents. A topographic survey conducted investigate alignment and intersections at hotspot locations. utilized Structural Equation Modeling (SEM) technique via SmartPLS highlight correlation designs analysis (Gits-Ord Gi) discovered 80 along highway. found that horizontal significantly impact accidents Furthermore, vertical has no effect areas. enhanced comprehension factors associated with geometrics affect occurrence
