Item Factors Influencing Post-encroachment Time of Road Crossing Pedestrians Near Bus Stops Located on Mid-Block Sections(Springer Science and Business Media Deutschland GmbH, 2024) Ajaykrishnan, M.J.; Sethulakshmi, G.; Mohan, M.The increase in road traffic poses a significant threat to vulnerable road users, heightening the demand for their safety. According to the recent Road Accidents Statistics (MoRTH, 2020), out of the total road accidents reported in 2020, 15.8% involved pedestrians, and 65.1% occurred on straight road sections. This highlights the difficulty and lack of safety for pedestrians. Lack of visibility is the major cause of most accidents, and in the case of bus stops, parked buses affect the visibility of crossing pedestrians. In this study, traffic safety of crossing pedestrians is analysed using the proactive approach, which identifies an observable non-crash event that could have led to a conflict. Post-Encroachment Time (PET) is the most popular time-based measure that is the least time-consuming for accurate estimation of surrogate safety. This paper focuses on determining factors which affect PET of pedestrian crossings at mid-block sections with designated or undesignated bus stops. Videographic surveys were conducted at two mid-block sections with bus stops in Kerala, where accidents to pedestrians are frequent. Kinovea software was used to extract data from the recorded video samples, and IBM SPSS software was used to outline the factors influencing PET. The study found PET of crossing pedestrians to have a high positive correlation with the time taken for the vehicle to approach the crossing pedestrian, while other factors like evasive action and compliance behaviour were negatively correlated. The study proposed a model that will enable the easy computation of PET values of crossing pedestrians. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
