Kansas City Speed Hump and Roundabout Standards
Kansas City, Missouri maintains standards and approval processes for traffic calming devices such as speed humps and for intersection treatments including roundabouts. This guide summarizes how the city evaluates requests, which departments enforce installation and maintenance, and what residents or developers must submit to start a project in Kansas City. It draws on the municipal code and city transportation guidance to explain typical criteria, timelines, and appeal routes so you can prepare an application or complaint accurately.
Overview of Standards and Approval Process
Street design, traffic control devices, and intersection changes in Kansas City are governed by city engineering standards and the municipal code. Requests for speed humps or roundabouts typically begin with an evaluation by the Department of Public Works or Traffic Engineering, which considers factors such as traffic volume, 85th percentile speed, collision history, roadway classification, and emergency vehicle access. Final installation requires city authorization and coordination with utilities and emergency services. For text of the municipal code covering streets and traffic control devices, see the City Code.

- Roadway classification: collector and local streets are primary candidates; arterial modification is restricted.
- Geometric standards: profile, length, and spacing for speed humps must meet city engineering specs.
- Safety checks: crash history and sight distance analysis required for roundabout feasibility.
- Emergency access: coordination with fire and EMS for any vertical roadway control.
