Frequently Asked Questions

Why do we need an informational guide for roundabouts?

The guide is comprehensive in recognition of the diverse needs of transportation professionals and the public for introductory material through design detail, as well as the wide range of potential applications of roundabout intersections. Roundabout operation and safety performance are particularly sensitive to geometric design elements.

How are roundabouts used to reduce traffic congestion?

Well- designed roundabouts have been found to reduce crashes (especially fatal and severe injury collisions), traffic delays, fuel consumption, and air pollution. They also have a traffic-calming effect by reducing vehicle speeds using geometric design rather than relying solely on traffic control devices. Roundabout design is an iterative process.

What are the manuals for federal lands Highway?

Federal Lands Highway maintains manuals relevant to all divisions or to a specific division. PDDM - the Project Development and Design Manual (PDDM) details the pre-construction process culminating in the final PS&E package. The following manuals apply to operations within the Central division of FLH:

Where can I find the AASHTO Highway Safety Manual?

While this web site is hosted by AASHTO, the Association works closely with the Federal Highway Administration (FHWA) Office of Safety (click here to visit the FHWA HSM web page) and the Transportation Research Board (TRB) Highway Safety Performance Committee on the content, software tools and training related to the HSM.
