New York City Pedestrian Ramp Locations and Measurements

New York City's dataset catalogs all pedestrian ramps, providing detailed geometric and condition measurements for each structure. The data was collected by Cyclomedia for the NYC Department of Transportation and was last updated in May 2022. It includes over 25 columns of technical specifications for each ramp.

Use Cases

• Identify ramps with potential non-compliance by filtering on `RAMP_RUNNING_SLOPE_TOTAL`, `RAMP_CROSS_SLOPE`, or `OBSTACLES_RAMP` columns.
• Analyze ramp distribution and density across neighborhoods using `Community Districts`, `Borough`, and the `the_geom` geospatial column.
• Prioritize maintenance by assessing ramp condition metrics like `DWS_CONDITIONS`, `PONDING`, and `COUNTER_SLOPE`.
• Correlate ramp features (`RAMP_WIDTH`, `LND_LENGTH`) with location attributes (`Police Precincts`, `City Council Districts`) for resource allocation studies.

Strengths

• Contains over 25 specific measurement and location columns per ramp, including `RAMP_LENGTH`, `RAMP_WIDTH`, and `LND_CROSS_SLOPE`.
• Geospatial data (`the_geom`) enables precise mapping and spatial analysis.
• Covers the entire geographic scope of New York City's five boroughs.

Limitations

• Measurements are not definitive for ADA compliance assessment, requiring further site inspection as noted in the description.
• The last update was in May 2022, so the data may not reflect recent construction or changes.
• Sample data and total row count are unavailable, making initial assessment of dataset scale difficult.
