Abstract:

This evaluation assesses the effects of the Federal Highway Administration’s (FHWA’s) investment in roundabout research and related activities on the availability and quality of such research, the adoption of roundabouts in the United States, and the impacts of those roundabouts on safety, operational, and environmental performance of the U.S. transportation system. Although it is difficult measure the effect of specific FHWA activities, the evaluation found strong evidence of FHWA’s influence on the acceptance, consideration, and adoption of roundabouts. The findings suggest that acceptance, consideration, and adoption are higher now than would have occurred without FHWA research and activities. FHWA laid the foundation for national adoption of roundabouts by providing empirical evidence of their safety and operational benefits, increasing awareness of and confidence in them among stakeholders, and contributing to the development of the design standards for implementation.
