Traffic calming program orientation

Please join us in the basement conference room at City Hall (301 E. Huron Street) on Tuesday, October 17 , 2017 from 6:30 p.m. to 8 p.m. for an overview of the City of Ann Arbor Traffic Calming Program including how to initiate traffic calming in your neighborhood and, what to expect throughout the traffic calming program. Staff will be available to answer questions.


The City of Ann Arbor Traffic Calming Program works to improve the quality of life and safety of neighborhood streets through the installation of traffic calming devices. The request-based program allows City staff to partner with the community to design safe streets for motorist, bicyclists, pedestrians, and children. The City Council adopted process is described in the City of Ann ArborTraffic Calming Guidebook (PDF).

Request Traffic Calming

Petitions for the Traffic Calming program are currently being accepted. Contact Traffic Calming project manager Cynthia Redinger (; 734.794.6410 x43632​) to discuss the petition process and Traffic Calming program qualifications. 

Current funding allows completion of one Traffic Calming project per year. Petitions are considered on a first come first served basis. The Traffic Calming process takes approximately one year from petition submittal to construction, unless other projects are queued in advance. 

If you have submitted a Traffic Calming request that did not result in traffic calming device installation, either because the project area did not qualify based on speed study results or neighborhood preference, you may contact Traffic Calming project manager Cynthia Redinger (; 734.794.6410 x43632​) to discuss re-petition options.
