- "This issue contains 17 papers, 8 concerned with roundabouts and 9 concerned with emergency evacuation. The following aspects of roundabouts are examined: crash prediction model 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; estimating 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. The papers on emergency evacuation examine the following: modeling emergency evacuation; changes in evacuation decisions between hurricanes Ivan and Katrina; dynamic traffic assignment evaluation of hurricane evacuation strategies; turning angle effect on pedestrian emergency egress; travel time reliability during evacuation; modeling hurricane evacuation demand; hurricane evacuee route choice decisions; bus contraflow lane in freeway evacuation; and modeling risk attitudes in evacuation departure choices"--publishers summary.
