Washington DC Taxi Trip Data with Airport Assignment

District of Columbia taxi trip data processed by the Department of For Hire Vehicles (DFHV) and the Office of the Chief Technology Officer (OCTO). Pick-up and drop-off locations are assigned to city blocks using a 250-meter radius tolerance from the DC Master Address Repository, and trips are also assigned to Reagan, BWI, or Dulles airports using locator polygons. Trip times are rounded to the nearest hour.

Use Cases

• Analyze trip volume patterns by the rounded pick-up and drop-off hour to identify peak demand periods.
• Map taxi activity by assigned block locations to study neighborhood-level transportation flows.
• Identify airport-bound trips using the airport assignment feature to assess ground transportation usage at Reagan, BWI, and Dulles.

Strengths

• Data is processed with spatial precision, assigning trips to city blocks using a defined 250-meter radius tolerance from official coordinates.
• Includes specific enrichment for airport trips using locator polygons for three major airports (Reagan, BWI, Dulles).
• Publicly released under a CC-BY license by the District of Columbia government, supporting transparency and reuse.

Limitations

• Trip times are rounded to the nearest hour, which reduces temporal granularity for precise time-series analysis.
• The spatial assignment of locations to blocks or airports may introduce inaccuracies due to the 250-meter tolerance and polygon boundaries.
• Data accuracy is disclaimed by the provider, as it is derived from electronic sources and provided for informational purposes only.
