New York State Traffic Control Device Inventory

New York State Department of Transportation maintains a list of traffic control devices it owns or operates, excluding New York City. The inventory includes traffic signals, street lights, beacons, and Intelligent Transportation Systems (ITS). The data was last updated in February 2022.

Use Cases

• Map device locations using Latitude (UTM Y [Meters]) and Longitude (UTM X [Meters]) for spatial analysis of infrastructure density.
• Analyze maintenance workload distribution by cross-referencing Maintaining Region and Device Type.
• Assess asset ownership patterns by comparing Owning Region and Maintenance Responsibility fields.
• Prioritize device inspection or upgrade schedules based on Device Priority and Intersecting Route traffic levels.

Strengths

• Contains 14 distinct columns detailing device attributes, location, and management.
• Provides UTM coordinates for precise geospatial plotting and analysis.
• Explicitly documents geographic exclusion (NYC boroughs) for clarity.

Limitations

• Row count and total device inventory size are unknown, limiting scalability assessment.
• Temporal coverage and update frequency are unspecified beyond a single snapshot date.
• Potential geographic bias as data excludes all devices within New York City.
