City Data Requests - Traffic Sensors in The Bronx

Technology and Data New York 4 Minutes Read · published February 06, 2026 Flag of New York

The Bronx, New York relies on municipal traffic sensors and datasets to monitor speeds, volumes and congestion. This guide explains where to find sensor datasets and APIs, how to request additional or historical data, which city office enforces access and device protection rules, and practical next steps for researchers, consultants and community groups.

Where to find traffic sensor data

Primary data for traffic counts, signal timing and related feeds is published through the New York City Department of Transportation and the NYC Open Data portal. Public datasets and API endpoints are published for reuse by developers and researchers; for agency-level or sensor-level records not on Open Data, submit a records request to the agency responsible for the equipment [1] or use FOIL for records not available online [2].

Access methods and APIs

  • Search the NYC Open Data portal for datasets (CSV, JSON) and dataset-level API endpoints.
  • Use the dataset "API" link on each Open Data record to call the Socrata API (SODA) for programmatic access and filtering.
  • Check dataset metadata for update frequency and license terms before bulk download.
Check dataset metadata fields for update cadence and contact info before relying on realtime claims.

Requests for non-published or sensor-level data

If the exact sensor feed or raw device logs are not published, you can:

  • File a formal records request with NYC DOT or the relevant agency for device-level logs and calibration files.
  • Contact the DOT Data or Traffic Engineering division to ask for clarification on published feeds and available APIs.
  • If a records request is denied, appeal under the municipal FOIL/appeal process described on the city portal.

Penalties & Enforcement

Enforcement and penalties for misuse, tampering or unauthorized access to traffic sensor hardware or restricted feeds are handled by the responsible municipal agency (typically NYC Department of Transportation) and may involve municipal code and criminal statutes. Specific monetary fines and statutory sections for sensor tampering or unauthorized access are not specified on the cited DOT data page; see the agency contacts cited for enforcement action [1].

  • Fine amounts: not specified on the cited page.
  • Escalation (first/repeat/continuing offences): not specified on the cited page.
  • Non-monetary sanctions: agency orders, equipment seizure, or referral for prosecution are possible though not itemized on the cited page.
  • Enforcer and inspections: NYC Department of Transportation and its Traffic Operations or Field Inspection units; complaints and reports can be submitted through agency contact pages and 311 channels [1].
  • Appeal/review: appeals typically follow the FOIL or agency administrative appeal routes; time limits for appeals are not specified on the cited FOIL landing page [2].
If you are unsure whether data is public, ask the agency before attempting device access or intrusive collection.

Applications & Forms

There is no single universal "sensor data" application; published datasets are downloadable directly from Open Data. For records not published, submit a FOIL/records request to the city agency. The FOIL portal explains submission, form and appeal steps but does not list per-item fees on the landing page [2].

How to prepare a records or data request

  • Identify dataset name, date ranges, and specific sensor IDs or locations you need.
  • Check Open Data and DOT dataset metadata first to avoid duplicate requests.
  • If records are not found, file a FOIL request naming the agency and the precise records sought.
  • Follow up with the agency contact or 311 if processing delays occur.

FAQ

How do I get raw traffic sensor logs for a specific Bronx intersection?
Search the NYC Open Data portal for the published dataset and dataset-level API; if logs are not published, submit a records request to NYC DOT specifying sensor ID, dates and format required. [1][2]
Are there fees to obtain sensor data?
Published datasets are free to download; fees for extensive records or reproduction are not specified on the FOIL landing page and may depend on the agency’s records rules. [2]
How long does a records request take?
FOIL statutory response times and agency processing times vary; specific time limits are not listed on the cited FOIL landing page. [2]

How-To

  1. Locate the dataset on NYC Open Data and review metadata and API links.
  2. Use the dataset API to filter and download the date ranges and sensor IDs needed.
  3. If the data is not public, prepare a FOIL/records request naming the precise records and submit to the relevant agency.
  4. Contact the DOT Data or Traffic Operations office for help with dataset interpretation or to request unpublished feeds.

Key Takeaways

  • Start with NYC Open Data for published traffic sensor datasets and APIs.
  • For non-published device logs, submit a FOIL request to NYC DOT naming sensor IDs and date ranges.
  • Enforcement and penalties for tampering are handled by DOT; specific fines are not specified on the cited pages.
