New York State Department of Transportation data shows the location of Centerline Audible Roadway Delineators (CARDS) installed on state highways to reduce run-off-the-road crashes. The dataset includes the county, route, reference markers, length in miles, and year constructed for each installation section. Data collection began in 2012 and is hosted on the data.ny.gov platform.
Use Cases
- Analyze the total length of rumble strips installed per year using Year Constructed and Length in Miles.
- Map installation locations by county and route for geospatial analysis using County and Route columns.
- Identify specific highway segments with safety treatments using From Reference Marker and To Reference Marker.
- Assess the annual pace of safety infrastructure rollout by aggregating Length in Miles by Year Constructed.
Strengths
- Data includes specific location identifiers (Route, From/To Reference Marker) for precise segment mapping.
- Contains a temporal dimension with Year Constructed, allowing for time-series analysis of installations.
- Provides a concrete safety measure (Length in Miles) for quantifying infrastructure deployment.
Limitations
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
- Description metadata is limited; actual data quality requires manual inspection after download.
