Four types of reactions from the leading vehicles were identified, including changing lanes, slowing down, speeding up, and making no response. This paper tries to fill the research gap by focusing on understanding highway tailgating scenarios and examining the leading vehicles' reaction using existing naturalistic driving data.Ī total of 1,255 tailgating events were identified by using the one-second time headway threshold criterion. Previous studies have explored the behavior of tailgating drivers and have reported effective solutions to decrease the amount or prevalence of tailgating. Tailgating is a common aggressive driving behavior that has been identified as one of the leading causes of rear-end crashes.
