This study aimed to evaluate how different interactions among categories of vehicles affect critical values for near-crash events indicators under heterogeneous traffic. The authors used a semi-automatic tool to extract the trajectories and speeds of various vehicle types. This research thoroughly examined the interaction profiles using surrogate indicators, such as time-to-collision (TTC) and post-encroachment time (PET) within heterogeneous traffic conditions. It was discovered that critical values obtained from different vehicle combinations varied significantly. This research enhances the understanding of the complexities inherent in heterogeneous traffic and emphasizes the significance of considering vehicle types when evaluating infrastructure and establishing safety standards. Prominently, greater attention should be given to vehicles with higher risk factors.
