Frequently Asked Questions

Traffic Calming

Where can I learn more about DOT’s overall approach to traffic calming and street design?

The Street Design Manual is a comprehensive resource for in-depth information on DOT's traffic calming toolkit. Another helpful resource is the School Safety Engineering Project General Mitigation Measures Final Report.

How can I get a speed bump installed on my block?

In general, speed bumps should be confined to local and residential streets. They should not be installed on a regularly scheduled local bus route, a designated local or through truck route or snow emergency route.

In cases where a speed bump has been requested adjacent to a school and it is not possible due to roadway conditions,  DOT may consider installing a Reduced Speed Zone. Reduced Speed Zones include 20 mph reduced speed limit signs accompanied by flashing beacons that operate during school hours.

Any individual or group can request a speed bump by emailing the Commissioner or writing a letter to the Commissioner, Department of Transportation, 55 Water Street, New York, NY 10041. It is helpful to include written indications of community support, such as a petition of support signed by a majority of the homeowners, residents, businesses, or other organizations on the block, a resolution of support from the local community board, or a letter of support from a local elected official.

How can I have a mid-block crosswalk installed on my street?

You may request a mid-block crosswalk by emailing the Commissioner or writing a letter to the Commissioner, Department of Transportation, 55 Water Street, New York, NY 10041. The decision on whether or not to install a mid-block crosswalk will depend on whether the location meets certain criteria, such as a sufficient volume of crossing pedestrians, and appropriate space for a traffic signal or stop sign installation.
