Abstract

This study was aimed at documenting, through exploratory computer modeling, the expected nature of blind versus sighted pedestrian crossing performance at roundabouts, and to gather preliminary data (via modeling) on alternative signalization concepts and their potential impact on traffic performance in roundabouts. This study is unique in that it represents a first attempt at the explicit modeling of pedestrian vehicle interactions at roundabouts in a micro-simulation traffic environment. The study uses observational data of gap perception behavior by blind pedestrians for incorporation into the logic of the model. Finally, the study for the first time explores some signalization alternatives for pedestrian crossings near roundabouts and tests their impact on roundabout system operation. (Author/publisher)
