Intercity Air, Bus, and Rail Facility Locations Across Multiple Years

Locations of airports with scheduled service, intercity bus stops, and intercity rail facilities for the years 2006, 2012, 2018, and 2021. The dataset is provided by the U.S. Bureau of Transportation Statistics (BTS) to identify rural areas with access to these transportation modes. It includes geographic coordinates, facility types, service levels, and identifiers for each record.

Use Cases

• Analyze rural access to intercity transport by querying the 'ruralSrv' and 'mode' columns across different 'year' snapshots.
• Map facility density by state using the 'State' and 'the_geom' (geometry) columns to visualize geographic coverage gaps.
• Assess changes in service levels over time by comparing the 'servicelvl' field for specific 'City_State' locations between 2006 and 2021.
• Identify multi-modal hubs by filtering records where 'hub' indicates a location with multiple 'mode' types (air, bus, rail).
• Correlate transportation access with county-level data using the 'cntySrv' field for regional socioeconomic studies.

Strengths

• Contains data for four distinct years (2006, 2012, 2018, 2021), enabling longitudinal analysis.
• Includes 19 distinct columns providing geographic, categorical, and identifier data per facility.

Limitations

• The exact number of rows (facility records) is unknown, preventing assessment of dataset scale.
• Bus stop data is sourced from the Intercity Bus Atlas and is not intended for real-time use, indicating potential staleness for current routing.
• Commercial reuse of the bus stop data is prohibited under its CC-BY-NC 4.0 license.
