This collection, containing materials ranging from 1896-2002, constitutes much of Kenneth Todd's work and research on roundabouts and traffic signals, particularly in the latter half of the 20th century. Included are photographs, engineering documents, and articles and reports on the safety, efficacy, and design of traffic circles and other signalling devices. Visual and audiovisual materials include reel-to-reel video and slides. The materials primarily relate to traffic management in the United States, but a significant portion of the collection consists of research on the implementation of roundabouts in the United Kingdom and other parts of Europe.
The Roundabouts sub-series contains 11 folders of dated articles, and 1 folder of undated items. The contentsrticles range from journal articles to technical reports from throughout the 20th century.
