The Vision Zero Project Unit within Transportation Services maintains a database that tracks existing locations with installed traffic calming measures. These measures are traffic islands, speed cushions and speed humps. The descriptions of these traffic calming measures can be found here.
Our traffic calming database refreshes at the end of each week to ensure the latest updates are available for public access and review.
The Vision Zero Projects Unit also maintains a spatial version of this dataset, which is also displayed on the public Vision Zero mapping tool. This spatial data is maintained and updated on a separate schedule.
