Traffic Calming

CDOT’s Traffic Calming Program is designed to make residential streets safer for drivers, pedestrians and bicyclists. The program uses several roadway engineering tools to “calm” vehicular traffic by making it slow down and move more safely.

Among the tools:

- Street speed humps

- Alley speed humps

- Curb bump-outs

- Traffic Circles

- Cul-de-sacs

CDOT's Tools for Safer Streets Guide provides descriptions of each tool and a map of where some of the tools are located in neighborhoods across the city. 

Various solutions are used to address specific traffic issues--there is no "one-size-fits-all" application of traffic-calming tools.  CDOT works closely with local aldermen to study areas and suggest solutions.

Traffic-calming applications require a consensus of the block.  If you are interested in traffic calming, please contact your local alderman.
