Traffic calming is a method of slowing traffic through physical treatments to streets that were originally designed primarily for vehicles. These physical treatments (such as speed humps and curb bump-outs) are intended to force a change in the behavior of people driving cars and improve conditions for people living, walking, and bicycling in local neighborhoods.
Through the City of Ann Arbor Traffic Calming Program, residents have a formal process for engaging the city in a partnership to perform technical analysis of traffic concerns on local streets and explore options for effective solutions.
