Pedestrians’ accidents with vehicles when they are trying to cross the streets are considered one of the most fatal accidents for pedestrians. So making a decision about accepting a proper gap is crucial for pedestrians. This paper, using video-taped data, investigates pedestrians’ gap acceptance in an unsignalized intersection and a midblock crosswalk in Tehran, Iran. Size of the accepted gaps, size and number of the rejected gaps and the waiting time are examined against pedestrians’ and traffic attributes, using statistical analysis and modeling approach. Statistical analysis revealed that gender, using cell-phone during crossing and accompanying a child strongly affects the pedestrian gap acceptance behavior. A latent variable, caution behavior, was defined based on some observable indicators and using structural equation modeling it was estimated and used as an input in a binary mixed logit model. 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.
