Traffic Circles in the U.S.: Safer Roads Ahead
Traffic circles may improve the flow of traffic; however, they can confuse drivers and present challenges for cyclists. To help you understand the future of road design, iBestTravel continues to provide insights into the latest developments and forecasts. Here’s the latest…
The Rise of Traffic Circles in the U.S.
The U.S. is increasingly adopting traffic circles, a road design that has long been embraced globally. Until the 1990s, circular intersections were relatively rare. Nevertheless, in the past 25 years, an estimated 10,000 have been constructed in cities and towns across the U.S., with many more planned. This growth lags behind countries like the U.K., which boasts nearly three times as many traffic circles despite being 40 times smaller in land mass.
Historical Significance: Columbus Circle
New York City’s Columbus Circle stands as one of the first traffic circles. Designed in the 19th century by William Phelps Eno during the creation of Central Park, it now serves traffic on Central Park South, Broadway, and Eighth Avenue-Central Park West.
Safety Benefits of Traffic Circles
Proponents assert that traffic circles, often referred to as roundabouts, are significantly safer than traditional intersections and enhance traffic flow since drivers do not have to stop and wait for red lights. Studies show that traffic circles can reduce collisions by 37% and fatal collisions by 90%, according to analyses by the Insurance Institute for Highway Safety (IIHS) and the Federal Highway Administration (FHWA). However, critics argue they may not effectively handle heavy traffic and, based on the design, can pose risks for cyclists. Another concern is driver confusion.
Traffic Circles Across the U.S.
Florida leads the U.S. in traffic circles, boasting approximately 600 as of 2022. Following Florida are Washington, Indiana, Wisconsin, and North Carolina in the top five states with traffic circles, with Carmel, Indiana, being recognized as the top city for their prevalence.
The trend towards more traffic circles indicates a shift towards safer and more efficient roadway designs, paving the way for a safer commuting experience for all road users.
