| 摘要： | In this paper the author documents the benefits of urban roundabouts in the State of Maryland with the case studies of three modern roundabouts: Towson Roundabout, Baltimore County; Annapolis Westgate Circle Roundabout, City of Annapolis, Anne Arundel County; and Mount Rainier Roundabout, Prince George's County. These three modern roundabouts are fairly new, ranging from a few months for the Mount Rainier Roundabout to over four years for the Towson Roundabout. The Annapolis Westgate Circle Roundabout is 2.5 years old. The purpose of these roundabouts was to address traffic operations and safety problems as well as urban revitalization issues. The study findings clearly show that these roundabouts have traffic operation and safety benefits. The average vehicle delay was reduced at all three roundabouts. Since the delay is directly related to the level of service, the traffic operations in these locations improved significantly. The evidence of the Towson and Annapolis roundabouts indicated that the roundabouts reduced injury accidents significantly. However, overall accident rates increased significantly in the Towson Roundabout due to increased "fender bender" property damage accidents. It is too soon for a before and after accident analysis at the Mount Rainier Roundabout. In addition, the survey findings indicated that these roundabouts are having a positive impact on urban revitalization. This finding is based on qualitative data. Overall, the author established the positive benefits of modern roundabouts in the State of Maryland. He recommends installing additional modern roundabouts in urban areas of the State to achieve the dual objectives of traffic operational improvements and revitalization. |
