Traffic Calming

This is an archived document. For current information on Traffic Calming, visit the FHWA Office of Safety.


The term "traffic calming" is often described as the combination of mainly physical measures that reduce the negative effects of motor vehicle use and improve conditions for nonmotorized street users. However, the term "traffic calming" also applies to a number of transportation techniques developed to educate the public and provide awareness to unsafe driver behavior.

As traffic calming techniques often differ, techniques include police enforcement and education only in some areas. In others, it means the employment of speed humps only, while in others it means the possible use of a wide array of techniques and devices. This web site is dedicated to all the known and/or electronically publicized transportation programs and studies that pertain to traffic calming.
