Pedestrian Crossing Behaviour at Signalized Intersection Crosswalks: An Observational Study of Factors Influencing Pedestrian Walking Speed, Safety Margin, and Violation

抄録

Even though mobile phones have innumerable benefits like convenient & faster communication, entertainment, and even life-saving opportunities, the frequent use of mobile in road environment has led to unintended safety and operational consequences. Recently, the research focus has extended from distracted drivers to distracted pedestrians. This study investigates different factors affecting pedestrian crossing speed, safety margin and violation behaviour at intersection crosswalks. In an observational study setting, 2360 pedestrains’ road crossing behaviour was observed across three signalized intersections in Kolkata city (India). OLS and binary logistic regression were used for modelling. Results revealed that young (<30 years) pedestrian walks faster and takes small safety margin. Pedestrian engaged in texting and eating/drinking/smoking walks slowly. Pedestrian accepts large safety margin against large vehicles. The model estimate showed longer red-light phase length encourages more signal violation. These results may provide insight into an ongoing discussion on how to tackle distracted pedestrians crossing the street.
