Accelerating Roundabouts in the United States: Volume VI of VII - Investigation of Crosswalk Design and Driver Behavior

This volume is sixth in a series of seven. The other volumes in the series are: Volume I - Evaluation of Rectangular Rapid-Flashing Beacons (RRFB) at Multilane Roundabouts, Volume II – Assessment of Roundabout Capacity Models for the Highway Capacity Manual, Volume III – Assessment of the Environmental Characteristics of Roundabouts, Volume IV – A Review of Fatal and Severe Injury Crashes at Roundabouts, Volume V – Evaluation of Geometric Parameters that Affect Truck Maneuvering and Stability, and Volume VII – Human Factor Assessment of Traffic Control Device Effectiveness. These reports document a Federal Highway Administration (FHWA) project to investigate and evaluate several important aspects of roundabout design and operation for the purpose of providing practitioners with better information, leading to more widespread and routine implementation of higher quality roundabouts. This research explored location and configuration of pedestrian crosswalks at roundabouts. Two experiments were conducted for this project. The first examined driver yielding behavior at roundabouts by having researcher-pedestrians attempt to cross at several crosswalks and several intersections. The second examined drivers’ eye-glance behavior by having participants drive through several roundabouts while wearing an eye-tracking device. Drivers were found to yield more often at the crosswalks at roundabout entries than at crosswalks at roundabouts exits and were also more likely to yield to pedestrians waiting at the splitter island than those waiting at the curb. A model of yielding behavior found crosswalk distance from circulatory roadway affected yielding percentage, but the effect was too small to be practically significant. Drivers spent a considerable amount of time glancing toward pedestrians and pedestrian-related signs and markings, reducing the amount of time they glanced at navigation aids.
