NYC Transit Safety Incidents and Metrics from 2019

Beginning in 2019, this dataset tracks safety-related incidents and performance indicators for New York City Transit subway and bus operations. It includes monthly metrics on collisions, accidents, and prevention measures. The data is published by data.ny.gov and was last updated in March 2026.

Use Cases

• Analyze trends in specific safety Metric types (e.g., collisions, injuries) over time using the Month column.
• Compare incident rates across different NYCT Departments (e.g., bus vs. subway operations) using the Department and Value columns.
• Monitor the monthly Value of key safety indicators like accident prevention metrics to assess program effectiveness.
• Identify seasonal patterns in safety incidents by aggregating Metric counts by Month.

Strengths

• Data covers a multi-year period from 2019 onward, enabling longitudinal analysis.
• Includes multiple safety dimensions through the Metric column (e.g., incidents, collisions, accident prevention).
• Provides organizational context via the Department column for comparative analysis.

Limitations

• Unknown total row count and file size, making computational requirements unclear.
• Sample data is unavailable, preventing assessment of data granularity and value formats.
• Potential for incomplete records if reporting standards changed over the 7+ year period.
