ABSTRACT

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 updates a similar synthesis published in 1982. 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. Some of the earlier benchmark studies are incorporated where appropriate.

The report is a product of the FHWA–NHTSA Speed Management Team.
