Traffic Calming for Rural 2-Lane Roads

Started: August, 2011 Ended: September, 2013 Project ID #4W3747 Status: Completed


The objective of this project is to summarize past and current work on traffic calming applications and recommend techniques to address safety issues along continuous, rural, 2-lane road sections on Federal Lands.


Traffic calming techniques which seek to reduce vehicle speeds with the intent of improving safety (reducing crashes) have seen increased use in the United States in recent years. Such techniques have also been applied internationally for many years with good success. However, the majority of traffic calming applications has historically been made in urban and suburban environments and often applied at spot locations. While this is understandable, given the high traffic volumes and safety “hot spots” that are present in such areas, it does not answer the question of which traffic calming techniques are available and applicable to rural, 2-lane segments. Such roadways comprise a large portion of those overseen by Federal Lands, including National Parks, National Forests, Fish and Wildlife Refuges, and Indian Lands. Additionally, documentation of traffic calming techniques which may be transferable to rural, 2-lane roadway sections has not been made to date. Finally, the work performed to date in a rural context has typically focused on spot treatments, rather than continuous highway sections. This project will address the previously identified knowledge gaps by examining past and ongoing work related to different traffic calming techniques and best practices for continuous roadway sections.
