• Provides up to 26 distinct weekly street segment summaries for half a year.
• Data is aggregated for spatial and temporal pattern analysis, sourced from official District agencies.

Limitations

• Records without a time of day or that could not be associated with a street segment were excluded, potentially creating bias.
• Data is limited to weeks 27 through 52 of a single year (2011), offering a narrow temporal snapshot.
