District of Columbia Moving Violation Summaries for 2009

District of Columbia data summarizes parking and moving violation ticket counts based on time of day, week of year, and violation category. The dataset supports queries for over 50 different violation combinations and provides aggregated street segment data for up to 26 weeks. It was created by the District of Columbia's Metropolitan Police Department and partner agencies from a DMV database.

Use Cases

• Analyze spatial patterns of violation types aggregated by street segment on a weekly basis.
• Create street segment heat maps to identify which parking violations occurred most frequently during specific time-of-day ranges.
• Query weekly data to get a DC-wide perspective on over 50 different combinations of violations.

Strengths

• Supports analysis of over 50 different violation combinations.
• Provides aggregated data for up to 26 distinct street segments, representing weekly summaries.
• Data is summarized by multiple temporal dimensions: time of day, week of year, and year.

Limitations

• Records without a time of day or those that could not be associated with a street centerline segment were excluded, potentially introducing selection bias.
• The dataset is a temporal crosstab summary, limiting access to raw, individual violation records.
• Temporal coverage is limited to the year 2009, which may not reflect current traffic patterns.
