Traffic Accident Risk Factors in Fortaleza, Brazil (2004-2008)

Rosa Lívia Freitas de Almeida from Universidade Federal do Ceará created a dataset of 118,830 traffic accidents in Fortaleza, Brazil, from 2004 to 2008. The data integrates multiple administrative systems and was used to investigate risk factors for fatal outcomes, identifying specific accident types and driver characteristics associated with higher odds of death.

Use Cases

• Modeling the odds of fatal outcomes based on accident type (e.g., bicycle, pedestrian, fixed obstacle collisions).
• Analyzing temporal risk patterns based on time of day (e.g., early morning) and day of week (e.g., Sundays).
• Investigating demographic and driver skill risk factors (e.g., male gender, unskilled drivers).
• Assessing the impact of road jurisdiction (e.g., federal roads) on accident severity.

Strengths

• Integrates data from four administrative systems (Traffic Accidents, Mortality, Hospital, and Vehicle databases).
• Contains 118,830 accident records over a 5-year period (2004-2008).
• Analysis provides specific odds ratios (OR) for key risk factors like bicycle accidents (OR=21.2).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the final integrated dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias specific to Fortaleza, Brazil, from 2004-2008.
