District of Columbia Taxi Trip Data with Airport Assignment

District of Columbia taxi trip data processed by 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 and rounded to the nearest hour, with airport assignments for Reagan, BWI, and Dulles. The Department of For Hire Vehicles provides this data for public transparency.

Use Cases

• Analyze trip patterns by comparing rounded pick-up and drop-off times to identify hourly demand fluctuations.
• Map taxi activity by studying block location assignments derived from original latitude and longitude coordinates.
• Assess airport-related traffic volume using airport assignments based on locator polygons for Reagan, BWI, and Dulles.
• Study spatial accuracy of trip origins and destinations using the 250-meter radius tolerance applied to the DC Master Address Repository.

Strengths

• Data includes geographic assignment to city blocks using a defined 250-meter search radius.
• Locations are enriched with airport assignments for three major airports using locator polygons.
• Trip times are processed to the nearest hour, enabling aggregated temporal analysis.
• Provided under a CC-BY license by the District of Columbia government for public use.

Limitations

• Original coordinates are processed and rounded, reducing temporal and spatial precision.
• Data accuracy is disclaimed by the provider, with no guarantee of completeness or currentness.
• Sample data and specific row/column counts are unavailable for assessing dataset scale.
