The aim of this study is to investigate the differences in car occupant injury severity recorded in AIS 2005 compared to AIS 1990 and to outline the likely effects on future data analysis findings. Occupant injury data in the UK Cooperative Crash Injury Study Database (CCIS) were coded for the period February 2006 to November 2007 using both AIS 1990 and AIS 2005. Data for 1,994 occupants with over 6000 coded injuries were reviewed at the AIS and MAIS level of severities and body regions to determine changes between the two coding methodologies. Overall there was an apparent general trend for fewer injuries to be coded at the AIS 4+ severity and more injuries to be coded at the AIS 2 severity. When these injury trends were reviewed in more detail it was found that the body regions which contributed the most to these changes in severity were the head, thorax and extremities. This is one of the first studies to examine the implications for large databases when changing to an updated method for coding injuries.
This paper describes the methodology for the assessment of the socio-economic impact of SAFESPOT applications. The applications selected for the assessment cover vehicle to vehicle (v2v) as well as vehicle to infrastructure (v2i) communication systems. The applications address main problem areas of road safety: accidents at intersections, accidents due to hazardous road and weather conditions and accidents due to over speeding and inappropriate distance. The assessment methodology relies in its core on cost-benefit analysis (CBA) as the most widespread tool to assess the profitability of applications form the society point of view. The assessment is however not limited to CBA but also considers the economic effects for particular stakeholder groups such as users, public authorities and the like. Their individual cost and benefits can be investigated in stakeholder analyses. Both elements, CBA and stakeholder analysis, form an integrated assessment approach which is applied here. The assessment makes use of the sound methodological base which was provided by projects such as SEiSS and eIMPACT. Some characteristics of co-operative systems however call for special attention within the assessment. Most prominently, the assessment will concentrate on a bundle of applications. The impact of this bundle will be assessed under the conditions of different business and service models. These issues will be addressed in the paper. Moreover, this paper also provides insight in likely patterns of results and first results of socio-economic impact assessment itself.
Die Griffigkeit ist die maßgebende Größe für die Übertragung der Langs- als auch der Seitenkräfte von Reifen auf die Straßenoberfläche und hat somit einen erheblichen Anteil an der Straßensicherheit. In Deutschland erfolgt die Erfassung der Straßengriffigkeit im Rahmen von Bauverträgen sowie der Zustandserfassung und -bewertung (ZEB) mit dem Seitenkraftmessverfahren (SKM). Mit der Veröffentlichung der Technischen Prüfvorschriften für Griffigkeitsmessungen im Straßenbau (TP Griff-StB) (SKM) durch die Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV) am 29.04.2008 ist derzeit das aktuellste Dokument für Griffigkeitsmessungen im Rahmen von Bauverträgen sowie der Zustandserfassung und -bewertung von Bundesfernstraßen mit dem Seitenkraftmessverfahren (SKM) herausgegeben worden. Dieses Dokument löst die TP Griff-StB (SCRIM) mit ihren drei Allgemeinen Rundschreiben ab und fasst die Ergebnisse aus verschiedenen Forschungsprojekten und Erfahrungen aus den regelmäßigen Messungen der Messgerätebetreiber zusammen.
In September 2004 the first international symposium called ESAR (Expert Symposium on Accident Research) was carried out at the University of Hannover (Germany). The idea for such international conference was to bring together experts from the fields of accident investigation teams worldwide to present their results for a common audience of people from government, industry and other universities. The first conference was a really sufficient one and followed by the second symposium also at the Hannover Medical School two years later in 2006. This two year rhythm was now continued with the third conference in Hannover again in 2008. It is planned to carry out ESAR every two years also in the future. ESAR is a scientific colloquium and can be seen as a platform for exchange of information on accident research issues based on methodologies of investigation, injury mechanisms and injury assessment, accident causation and other issues of statistical accident data analysis. Representatives from authorities as well as from medical and technical institutions come together to discuss new research issues and exchange experiences on accident prevention and the complex field of accident reconstruction. Special focus was given to the target the European Union set for itself in 2000 which stipulates that within 10 years the number of person killed in road traffic accidents must be cut in half. To reach this goal, optimized measures, comprehensive research and analysis are necessary. A key hurdle comes from the European Union extension to 27 member states, each featuring different levels of traffic safety standards and different accident scenarios. Existing results from long term research projects in Europe, the USA, Australia and Japan including analyses of infrastructure, population, vehicle fleet and driver behaviour offer an excellent basis for understanding and improving countermeasures and research support needs in underdeveloped countries. ESAR's goal is to bring together researchers from all parts of the world, who will report on their methods and recommendations to improve traffic safety based on "In-Depth-Investigations" of real world accidents. These In-depth-investigations of accidents require thorough documentation and an accident data analysis on multidisciplinary levels which must be carried out immediately after it occurs. ESAR presents scientists the opportunity to present their studies on a common basis of research level.
