NYC Vision Zero Traffic Crash Injuries And Fatalities

Monthly aggregated data populates the Vision Zero View map tracking traffic deaths and injuries in New York City. The data is sourced from the NYPD's Traffic Accident Management System, with crashes mapped to the nearest intersection on a simplified street model. Injuries and fatalities are grouped by intersection and summarized by month and year.

Use Cases

• Analyze monthly and yearly injury and fatality trends grouped by intersection to identify high-risk locations.
• Map crash data aggregated to the nearest intersection onto a simplified NYC street model for spatial risk assessment.
• Exclude highway injury and fatality crashes to focus analysis on city street and intersection safety.

Strengths

• Data is aggregated and updated on a monthly basis, providing regular refreshes.
• Crashes are mapped using a validated geographic process, ensuring only incidents with valid location data are included.
• The data supports a specific public policy goal (Vision Zero) for ending traffic deaths and injuries.

Limitations

• Data is preliminary and may contain errors, as explicitly noted by the provider.
• Midblock crashes are mapped to the nearest intersection, which may reduce locational precision for analysis.
• Complex intersections with multiple roadways are represented by a single point, simplifying spatial reality.
