Fatal Crashes from Signal and Stop Sign Violations, 1999-2000

1999 and 2000 Fatality Analysis Reporting System data was analyzed to understand fatal crashes involving light vehicles violating traffic signals or stop signs. The report covers 9,951 vehicles in fatal crashes at signals and 13,627 at stop signs, analyzing crash scenarios, contributing factors, and infrastructure. It was authored by B N Campbell.

Use Cases

• Analyze crash scenario patterns based on single, two-vehicle, and multi-vehicle crash categories.
• Study the relationship between alcohol involvement and crash type based on the reported rates.
• Model the prevalence of speeding and inattention as contributing factors across different crash categories.
• Investigate infrastructure characteristics where fatal signal and stop sign violations occurred.

Strengths

• Analysis covers two years of national fatal crash data (1999 and 2000).
• Provides specific counts of involved vehicles: 9,951 at signals and 13,627 at stop signs.
• Reports detailed violation percentages, such as 20% failing to obey signals and 23% failing to yield at stop signs.
• Compares factors like alcohol involvement and speeding rates across three distinct crash categories.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data may reflect temporal bias inherent to the 1999-2000 collection period.
