Walking is the most sustainable transportation mode, while pedestrians are the most vulnerable road users. Understanding the nature of their interactions with vehicles, particularly at unsignalized crossings, is critical to improving road safety. Due to advances in video-based vehicle trajectory processing, road safety analysis methods have evolved significantly, and there is an increasing preference for the use of Surrogate Measures of Safety (SMoS) to describe the road safety situation at a given location. There is a lack of such studies for pedestrian-vehicle interactions. The aim of this paper is to fill this gap and present preliminary results derived from video recordings at an unsignalized pedestrian crossing in Gyor, Hungary. Post-encroachment time (PET) as a SMoS was generated using an automated road safety analysis software, TrafxSAFE, a product of Transoft Solutions. 594 videos (of approximately 85 h and 48 min) were analyzed in this study. It is concluded that there are differences in the probability of conflicts depending on the direction from which the pedestrian and the vehicle approach the crossing. Conflicts where pedestrians and vehicles approach the crossing in the same lane are slightly more likely to occur, as there is less time for the road users to take evasive action.
