The aim of STAIRS was the standardization of in-depth road accident data collection and methodologies. This objective focuses mainly on secondary safety or injury prevention and is divided into five Work Packages:
Work Package 1 involved developing a protocol for the collection and processing of injury and vehicle data from road crashes. It specifies the criteria required for data to be included in a harmonized European injury database. The Work Package concentrates on the systems and data required for the development of injury prevention methods, or for the evaluation of any new safety measures that may be introduced in the future. It includes the following topics:
- A review of existing studies,
- Values and variables,
- Data collection,
- Data accuracy,
- Validation
- Confidentiality and ethics.
Workpackage 2 is about the linking of in-depth accident databases to Regional, National accident databases. For the purposes of this document the methodological approach has only been applied to the 1st step of the linkage. Linkage between In-depth and Regional accident databases has been demonstrated for France, Germany and the UK. In all three countries it has been necessary to check the adequacy of the linking and weighting process, this has been illustrated by means of examples. For National levels, statistical requirements and sampling considerations have been proposed without examples.
Work Package 3: The processes of external consultation that members of the consortia developed are the main topic of this Work Package. These range from: conference papers at prestigious events throughout the world; presentations to interested groups and organizations involved in, or associated with, in-depth crash investigation; a workshop attended by a selection of delegates from the areas of research, government and manufacturing; and the development of a World Wide Web site (
www.ice.co.uk/stairs) in order to disseminate the group's work and findings to as large an audience as possible.
Work Package 4 : This is a full report on the workshop mentioned above. The idea of the workshop was to begin a two-way discussion between the interested parties and the STAIRS partners. It was hoped that from these discussions the protocols developed could better reflect the wants and needs of a wider target audience. Presentations were given on all of the areas in Work Packages 1 and 2 to a selection of delegates from the differing areas of research, government and vehicle manufacturing. Discussion and feedback was encouraged at key points throughout the day. The workshop was discussed by the group and it was agreed that the outcome was extremely positive. The feedback was helpful, and areas identified for further work or clarification.
