District of Columbia Moving Violations Summary for 2015

A 2015 summary of parking and moving violations issued by the District of Columbia's Metropolitan Police Department and partner agencies. The data is aggregated by week, time of day, and over 50 violation types to show spatial patterns across 26 distinct street segments per half-year.

Use Cases

• Create street segment heat maps using weekly aggregated data to visualize spatial patterns of violations.
• Analyze the frequency of specific violation types across the 26 weekly street segments to identify enforcement hotspots.
• Query data by week to examine temporal trends in violation categories across different times of day.
• Compare violation counts across the defined time-of-day ranges to understand peak enforcement periods.

Strengths

• Covers over 50 different combinations of violation types for detailed analysis.
• Provides a weekly perspective with data aggregated across 26 distinct street segments per half-year.
• Data is sourced from authoritative District agencies including the Metropolitan Police Department and DMV.

Limitations

• Records not associated with a street centerline segment or lacking a time of day were excluded, potentially omitting some violations.
• The data is summarized and aggregated, not raw incident-level data, limiting granular analysis.
• Temporal coverage is limited to the year 2015, which may not reflect current patterns.
