Single-vehicle collisions in Europe: analysis using real-world and crash-test data

Journal article, 2008

Many European road casualties result from vehicles leaving the road, often impacting roadside obstacles. As part of the European Commission-funded project RISER (Roadside Infrastructure for Safer European Roads), several activities were undertaken to collate the type of real world crash data which is needed to understand single vehicle crash situations and relate this to crash-test data mandated in the European Union. Accident data were collected and used to create databases exclusively for single-vehicle collisions on major rural roads, simulation software was used to further understand impacts with roadside structures, and an inventory of crash-test data was collected for impacts with poles and safety barriers. The combination of accident data, simulations and crash-test data has provided a unique insight into the characteristics of single-vehicle collisions, helping those involved in the design and evaluation of the roadside environment to understand them better and make recommendations for consideration when drafting design guidelines.
