Road safety has traditionally relied on crash data. Crashes are the ultimate and most critical outcome of any kind of road conflict, making them rare and random events. Study of crashes to find the hazardous patterns between road users requires years of data, causing ethical and practical concerns. Alternatively, the observation of interactions and conflicts between road users can provide useful information about the hazardousness and safety of a location. To evaluate the severity of the conflicts, surrogate safety measures are mainly used. Time-to-collision (TTC), being used in this study, is the Time remaining before a collision occurs between two vehicles, assuming that their current trajectory and speed difference remain unchanged.
