Traffic Calming

The Process


Traffic calming is the practice of combining physical measures to reduce the negative impacts of motor vehicle use by altering driver behavior and to improve the environment for non-motorized street users.

Landscape Medians


A landscape median is a raised landscaped island located along the center-line of a street that narrows the adjacent travel lanes.

Placed at the entrance of a neighborhood, the median can serve as both a gateway into the neighborhood and a way to slow down traffic.

Traffic Circles


Traffic circles are raised islands, placed in intersections, around which traffic circulates. Circles are used for calming intersections where large vehicle traffic is not a major concern but speed, volume, and safety are problems.

Speed Humps


Speed humps are rounded raised areas of asphalt placed across the roadway. A speed hump provides the most aggressive form of traffic calming and is beneficial in locations where low speeds are desired.
