Pedestrian's crossing from unsignalized locations at intersections or midblock locations is a risky decision that could lead to fatal accidents. Despite making a decision to accept a safe gap to cross the street is a personal choice, studying this phenomena and its affecting variables are crucial for accident analysis and traffic safety investigations. In this paper we used video taped data to study pedestrian gap acceptance behavior at an unsignalized intersection and a midblock facility in Tehran, Iran. Multi way ANOVA test indicates simultaneous effect of gender and child accompaniment have the highest effect on size of accepted gap and waiting time. In addition, number of rejected gap is mostly affected by the child accompaniment status. Investigation about critical gap shows in general, critical gap was bigger at unsignalized intersection and for women. We defined a latent variable named caution behavior based on some observable indicators and using structural equation modeling it was estimated and used as an input in a binary mixed logit model. This variable identified important in gap acceptance decision. Despite both structural equation and logit models are used in previous gap acceptance studies, but according to our best knowledge this is the first use of the hybrid mixed logit modeling approach in this field and we developed a new methodology to combine psychological and behavioral aspects of pedestrians' gap acceptance studies. Modeling approach shows pedestrian decision regarding acceptance or rejection of a gap to be highly influenced by the size of current gap, caution behavior and waiting time.
