NORTH CAROLINA STATE UNIVERSITY. “The effects of roundabouts on pedestrian safety”. Raleigh, Department of Civil Engineering, Raleigh, NC, USA. pp 50. August 2002. This research seeks to examine the safety issues by summarizing the literature that describes international and U.S. experience with roundabouts and pedestrian safety. The research applies three alternate approaches to assess pedestrian safety at roundabouts: case study analysis, statistical analysis, and simulation analysis to compare pedestrian safety at a conventional signalized intersection to a case study modern roundabout.
