NYC Automated Traffic Volume Counts for Bridges and Roadways

Automated Traffic Recorders (ATR) collect sample traffic volume counts for New York City bridge crossings and roadways. The New York City Department of Transportation (NYC DOT) gathers this data, which does not cover the entire year and varies in days counted per location annually. The dataset was last updated on March 20, 2026.

Use Cases

• Analyze annual traffic volume trends using the Yr and Vol columns.
• Map traffic counts to specific street segments using the street, Boro, and WktGeom columns.
• Compare directional traffic flow using the Direction, fromSt, and toSt columns.
• Aggregate counts by hour of day using the HH column alongside the MM column for minute-level detail.

Strengths

• Includes geospatial coordinates via the WktGeom column for mapping.
• Contains temporal granularity with Yr, MM, and HH columns.
• Data is sourced directly from the New York City Department of Transportation (NYC DOT).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Counts are samples and do not cover the entire year, with varying days counted per location.
