Brooklyn City Guide to Speed Bump and Roundabout Requests

Transportation New York 4 Minutes Read ยท published February 02, 2026 Flag of New York

In Brooklyn, New York, residents and community boards typically request traffic-calming measures such as speed humps or roundabouts through city agencies. This guide explains who decides, how to apply, what factors agencies consider, enforcement pathways, and practical steps to request or appeal a decision in Brooklyn. Follow the local process, document issues, and use official request channels to improve safety on your street.

How requests are handled

Traffic-calming installations in Brooklyn are evaluated and implemented by the New York City Department of Transportation (NYC DOT) in coordination with local community boards and, where applicable, the New York City Police Department for enforcement. Requests begin with a documented complaint or service request and proceed through design review, field studies, community outreach, and final approval. For official project descriptions and program criteria see the DOT traffic-calming resources[1] and the NYC 311 request pathway for reporting and tracking street-safety requests[2].

Start by collecting dates, times, and photos before you file a request.

Typical evaluation criteria

  • Traffic volumes and speed data collected by DOT or requested via 311.
  • Collision history and pedestrian injury records.
  • Proximity to schools, parks, senior centers, and transit stops.
  • Street geometry, bus routes, hydrants, and fire apparatus access.
Roundabout feasibility often requires intersection analysis and may be uncommon on narrow Brooklyn streets.

Penalties & Enforcement

Installation and maintenance of official traffic-control devices is managed by NYC DOT; enforcement of traffic laws at sites where devices are installed is handled by the NYPD. Penalties for tampering with, removing, or installing traffic-control devices without authorization are enforced under city and state laws and by the responsible agencies.

  • Fine amounts: not specified on the cited page.
  • Escalation: first, repeat, or continuing offence details are not specified on the cited page.
  • Non-monetary sanctions: orders to restore the roadway, removal of unauthorized devices, and court action where applicable; specific remedies are not specified on the cited page.
  • Enforcer and complaints: NYC DOT (design/installation) and NYPD (traffic enforcement). Use NYC 311 or DOT contact pages to report or request inspections.[2]
  • Appeals and review: formal appeal pathways and statutory time limits are not specified on the cited page; requests and disputes are handled through DOT project review and city administrative processes.
  • Defences and discretion: agencies evaluate technical criteria and may grant exceptions or alternative measures; specific discretionary standards are not specified on the cited page.
If you find an unauthorized device, report it through 311 immediately.

Applications & Forms

There is no separate public paper form for speed-hump or roundabout requests published as a standalone DOT application; residents should file a service or complaint request through NYC 311 or follow DOT project intake instructions on the DOT site.[1][2]

Design, timeline, and community input

After a request is received, DOT may conduct field measurements and traffic studies, share design proposals with the local community board, and hold public outreach. Timelines vary by project complexity and funding; exact schedules are not specified on the cited pages.

Community board support and clear data improve chances of approval.

Action steps for residents

  • Document issues: record dates, times, speeds, and photos of problematic behavior.
  • File a 311 request for traffic-calming or a DOT service request and save the reference number.[2]
  • Contact your community board and elected officials to request support for a DOT review.
  • Follow up with DOT project contact information given in response; ask for study dates and expected milestones.
