Traffic Calming Measures


A series of fact sheets providing an overview of several traffic calming measures are available from this Web page. A photograph of a typical application as well as a plan-view sketch adapted from the Boulder, Colorado Neighborhood Traffic Mitigation Program Toolkit are included within each fact sheet.

Four types of measures are summarized:

  • Vertical deflections, horizontal shifts, and roadway narrowings are intended to reduce speed and enhance the street environment for non-motorists.
  • Closures (diagonal diverters, half closures, full closures, and median barriers) are intended to reduce cut-through traffic by obstructing traffic movements in one or more directions.

The information provided on these fact sheets has been obtained from the research and experience of transportation engineering and planning professionals. The information is intended for informational purposes only and does not include ITE or FHWA recommendations on the best course of action.

Photos of traffic calming devices were provided by Reid Ewing.

 









For each traffic calming measure, information has been compiled from a variety of sources, including:

Traffic Calming: State of the Practice (ITE/FHWA)

Canadian Guide to Neighbourhood Traffic Calming
(TAC and CITE)

Traffic Calming Primer (Pat Noyes & Associates)

Guidelines for the Design and Application of Speed Humps (ITE)
