Abstract

Washington's street network has often been called unique, presenting unusually complex traffic patterns. Actually, it is doubtful whether the problems differ greatly from those in Chicago, Boston, or New Orleans. The difficulty is fundamentally the same in every major city. All have vehicular and pedestrian congestion wherever public interest focuses on a common area. Washington is probably the only city of colonial origin that received the benefits of scientific planning in the early day of its founding. This article deals with traffic circles, the complexities of vehicular and pedestrian control arising from them, and the methods employed to overcome the deficiencies inherent in all rotary movements of traffic.
