Transportation Michigan 3 Minutes Read ยท published February 07, 2026 Flag of Michigan

Detroit, Michigan residents can request a traffic calming study to evaluate speed bumps and other measures on neighborhood streets. This guide explains the city offices involved, the typical review steps, how to submit a request, and what enforcement or appeals may follow. Use official city pages to start a request and to confirm current forms and timelines.

Overview

The City of Detroit Department of Public Works (DPW) administers traffic calming evaluations and coordinates with Traffic Engineering and Detroit Police Department for safety and enforcement. To begin, gather location details, collision data if known, and neighbor support; then submit a request to the DPW for screening and possible study. The DPW traffic calming program page describes the program functions and contact route[1].

Traffic calming requests begin with DPW screening; assessment and installation are separate steps.

Process to Request a Traffic Calming Study

Typical municipal steps include submission, engineering screening, traffic counts/observations, public outreach, design recommendation, and final approval for installation. City traffic and vehicle rules are codified in the Detroit municipal code and govern lawful placement and controls for traffic devices[2]. To submit a request or ask about status, use DPW contact routes and customer service channels[3].

  • Prepare: exact street segment, nearest cross streets, photos, and any collision or speed data.
  • Collect community support: petitions or neighborhood association statements help triage requests.
  • Submit: use DPW submission methods listed on the official DPW page.
  • Study: engineering collects traffic counts and recommends solutions.
  • Installation: approved devices are scheduled and installed by city crews or contractors.
Gathering neighbor support and clear location details speeds initial screening.
