The roundabout papers examine crash prediction models for roundabouts on high-speed rural roadways; vehicular capacity at multilane roundabouts with consideration of pedestrian crossings; public perceptions of roundabouts; estimating roundabout capacity; vehicle travel position on roundabouts in cold regions; vehicle delay on single-lane roundabouts; driver responses to pedestrian treatments at multilane roundabouts; and delay analysis of a single-lane roundabout with a slip lane. Papers in this TRR that address emergency evaluation examine emergency evacuation modeling; changes in evacuation decisions from hurricanes Ivan and Katrina; dynamic traffic assignment evaluation of hurricane evacuation strategies; turning angle effects on pedestrian emergency egress; travel time reliability during evacuations; modeling hurricane evacuation demand; hurricane evacuee route choice decisions; bus contraflow lanes in freeway evacuation; and modeling risk attitudes in evacuation departure choices.
