District of Columbia Parking Violation Summaries for 2011 First Half

26 weeks of aggregated parking violation data from Washington D.C.'s Vision Zero initiative, summarized by week and time of day. The dataset provides a DC-wide perspective on over 50 different violation combinations, with records excluded if they lacked a street segment or time-of-day association.

Use Cases

• Analyze weekly patterns of over 50 violation types to identify enforcement hotspots for urban planning.
• Create street segment heat maps using the weekly aggregation to visualize spatial patterns of parking offenses.
• Query violation counts by week and time-of-day ranges to assess temporal trends in traffic enforcement.

Strengths

• Covers 26 distinct weeks of data, providing a half-year temporal perspective.
• Includes over 50 different combinations of parking violation types for analysis.
• Data is aggregated for spatial visualization, specifically for creating street segment heat maps.

Limitations

• Records without a time-of-day or a street centerline segment association were excluded, potentially biasing the sample.
• The data is a summary aggregation, not raw ticket-level records, limiting granular analysis.
• Temporal coverage is limited to the first 26 weeks of 2011, which may not reflect current patterns.
