Dataset Creation
Curation Rationale
This dataset was created to advance AI capabilities in road safety, automated navigation, and urban planning. It supports visual recognition of traffic elements specific to Brazil’s highway code and driving environments.
Source Data
- Contributors: Field data collection and publicly available road imagery under open licenses
- Collection Process: Images were captured from highways, urban streets, and rural areas across Brazil. Each sign was categorized by type (regulatory, warning, informational, or guide). Personally identifiable data (faces, license plates) was blurred or removed.
Other Known Limitations
- Bias: Overrepresentation of urban traffic signs compared to rural or regional variants
- Weather and Lighting Variability: Conditions may affect clarity and detection accuracy
- Geographical Coverage: Certain states or remote roads may have limited representation
Intended Uses
✅ Direct Use
- Training computer vision models for traffic sign recognition
- Research in autonomous driving and ADAS development
- Road infrastructure mapping and visual classification
- Traffic monitoring and safety compliance analysis
- Academic work on multilingual and symbolic sign understanding
❌ Out-of-Scope Use
- Real-time surveillance or tracking of individuals or vehicles
- Misuse for commercial mapping without authorization
- Use in law enforcement decision-making without human review
