Abstract
Motor vehicle crashes involving pedestrians have recently become a major traffic safety problem. Pedestrian error is defined as a risk event that can be described by uncensored waiting duration. This paper presents a parametric duration model for analysis of pedestrian behaviour in midblock crosswalk and intersection, which can be used to explain when and why pedestrians cross the street in error. In order to identify individual differences in pedestrian behaviour based on specific error-inducing factors in midblock crosswalk and intersection, the endurance probability and risk rate for pedestrian crossing behaviour are calculated with different waiting durations by the exponential, Weibull and log-logistic distributions. The results show the relationship of pedestrian behaviour and waiting duration.
