District of Columbia Moving Violation Summaries for 2011

Moving violation data from Washington DC's Vision Zero initiative, aggregated by street segment, week, and time of day. The dataset provides a DC-wide perspective on over 50 different violation combinations, with summaries excluding records lacking location or time information.

Use Cases

• Analyze spatial patterns of violation types across 26 distinct street segments to identify high-risk corridors.
• Create weekly heat maps of ticket counts based on time of day and week of year for targeted enforcement planning.
• Query violation category frequency by week to determine the most common parking infractions during the half-year period.

Strengths

• Covers over 50 different combinations of moving violation types.
• Data is aggregated into 26 distinct street segments, providing weekly spatial granularity.
• Summaries exclude records without associated street segments or times, improving location and temporal data integrity.

Limitations

• Data is summarized and aggregated, losing individual ticket-level detail for analysis.
• Records without associated street centerline segments or times were excluded, potentially introducing selection bias.
• Temporal coverage is limited to a half-year period from 2011, which may not reflect current traffic patterns.
