District of Columbia Parking Violations Summary for 2009 Weeks 1-26

2009 data from Washington D.C. summarizes parking violation ticket counts by time of day, week of year, and violation category. The dataset provides a weekly, DC-wide perspective on over 50 different violation combinations, aggregated into 26 distinct weekly street segments.

Use Cases

• Analyze weekly patterns of specific violation types across 26 weeks to identify enforcement hotspots.
• Create street segment heat maps showing the distribution of violation categories by time of day ranges.

Strengths

• Covers over 50 different combinations of parking violation types.
• Provides 26 distinct weekly summaries for temporal analysis.
• Aggregated from enforcement data by the Metropolitan Police Department and partner agencies.

Limitations

• Records not associated with a street centerline segment or lacking a time of day were excluded, potentially biasing spatial coverage.
