ROASta

ROASta, short for Road Accident Statistics Analysis, is a framework designed to standardize the collection, integration, and analysis of road accident data to support safety research and policy development. It seeks to enable comparability across jurisdictions by defining a common data model, harmonized taxonomies, and interoperable data exchange protocols, while emphasizing privacy and data protection.

Origin and governance: ROASta emerged from discussions among international safety and transportation stakeholders in the early 2010s, with contributions from government agencies, research institutions, and industry partners. A dedicated governance body oversees recommended definitions, release cycles, and best practices, while participation remains voluntary and varies by region and agency.

Technical core: The framework provides a core data model that covers accident identifiers, location and time, incident factors, vehicle types, vulnerable road users, injury outcomes, and environmental conditions. It establishes standardized codes for injury severity and crash types and includes a metadata registry, validation rules, and documentation. Data exchange supports common formats such as JSON and XML, with optional semantic layers to enable more advanced queries and interoperability.

Implementation and impact: ROASta is designed to enable data integration from police reports, hospital records, road weather datasets, and infrastructure sensors, improving the quality and comparability of road safety analyses. Potential benefits include faster insight generation, more consistent cross-border research, and better-informed policy interventions. Challenges include varying data quality, legacy information systems, resource limitations, and the ongoing need for privacy protections and ethical data use.
