Assessment of Traffic Safety Between Pedestrians and Vehicles Using Traffic Conflict Technique

This paper presents a method to assess pedestrian safety, the traffic conflict technique was used to detail potential hazards or collisions with pedestrians at crosswalks. We use two parameters of this technique to describe the conflict process including the time to conflict (TTC) and post-encroachment time (PET), which have been proven effective in the evaluation of pedestrian traffic safety. In addition, the conflicting data will be classified through the K-means classification algorithm to identify the danger level of the conflicting points and areas, thereby proposing the appropriate solution to minimize conflict areas, which have a high risk to traffic safety.
