District of Columbia Moving Violation Summaries for 2014

Over 50 different violation combinations are aggregated by week and time of day for street segments in Washington, D.C. The dataset provides a temporal crosstab to analyze spatial patterns of parking and moving violations issued by the Metropolitan Police Department and partner agencies. Records without associated street segments or times were excluded.

Use Cases

• Create weekly street segment heat maps using aggregated violation counts to identify spatial patterns of traffic enforcement.
• Analyze the frequency of specific violation types across defined time-of-day ranges to understand temporal enforcement trends.
• Query data by week to compare DC-wide yearly and weekly perspectives on over 50 violation combinations.

Strengths

• Covers over 50 distinct combinations of moving and parking violations.
• Data is aggregated into 26 distinct street segments, representing each week of a half-year period.
• Summarized by multiple temporal dimensions: week of year, year, and time of day.

Limitations

• Records lacking a geocoded street segment or an associated time of day were excluded, potentially introducing selection bias.
• The data is aggregated and summarized, limiting analysis to pre-computed crosstabs instead of raw incident records.
• Temporal coverage is limited to the year 2014, which may not reflect current traffic patterns or enforcement policies.
