This report presents a synthesis of research findings on the safety effects of speed, speed limits, enforcement, and engineering measures to manage speed. The report is the update of research on speed and speed control that was originally published in 1963 and updated in 1970 by the Highway Users Federation for Safety and Mobility as a chapter in "Traffic Control and Roadway Elements -- Their Relationship to Highway Safety." The synthesis was updated again in 1982 by the Federal Highway Administration. A great deal of speed related research has been carried out since that time. This synthesis highlights the results of significant safety research related to speed completed since the last update in 1982. Some of the earlier benchmark studies are summarized where appropriate. The report is a product of the FHWA-NHTSA Speed Management Team. (Author/publisher)
