Since its beginning in 1999, the German In-Depth Accident Study (GIDAS) evolved into the presumably leading representative road traffic accident investigation in Europe, based on the work started in Hanover in 1973. The detailed and comprehensive description of traffic accidents forms an essential basis for vehicle safety research. Due to the ongoing extension of demands of researchers, there is a continuous progress in the techniques and systematic of accident investigation within GIDAS. This paper presents some of the most important developments over the last years. Primary vehicle safety systems are expected to have a significant and increasing influence on reducing accidents. GIDAS therefore began to include and collect active safety parameters as new variables from the year 2005 onwards. This will facilitate to assess the impact of present and future active safety measures. A new system to analyse causation factors of traffic accidents, called ACASS, was implemented in GIDAS in the year 2008. The whole process of data handling was optimised. Since 2005 the on-scene data acquisition is completely conducted with mobile tablet PCs. Comprehensive plausibility checks assure a high data quality. Multi-language codebooks are automatically generated from the database structure itself and interfaces ensure the connection to various database management systems. Members of the consortium can download database and codebook, and synchronize half a terabyte of photographic documentation through a secured online access. With the introduction of the AIS 2005 in the year 2006, some medical categorizations have been revised. To ensure the correct assignment of AIS codes to specific injuries an application based on a diagnostic dictionary was developed. Furthermore a coding tool for the AO classification was introduced. All these enhancements enable GIDAS to be up to date for future research questions.
The levels of continuous vehicle automation have become common knowledge. They facilitate overall understanding of the issue. Yet, continuous vehicle automation described therein does not cover "automated driving" as a whole: Functions intervening temporarily in accident-prone situations can obviously not be classified by means of continuous levels. Continuous automation describes the shift in workload from purely human driven vehicles to full automation. Duties of the driver are assigned to the machine as automation levels rise. Emergency braking, e.g., is obviously discontinuous and intensive automation. It cannot be classified under this regime. The resulting absence of visibility of these important functions cannot satisfy " especially in the light of effect they take on traffic safety. Therefore, in order to reach a full picture of vehicle automation, a comprehensive approach is proposed that can map out different characteristics as "Principle of Operation" at top level. On this basis informing and warning functions as well as functions intervening only temporarily in near-accident situations can be described. To reach a complete picture, levels for the discontinuous, temporarily intervening functions are proposed " meant to be the counterpart of the continuous levels already in place. This results in a detailed and independent classification for accident-prone situations. This finally provides for the visibility these important functions deserve.
Anforderungen, Zielkonflikte
(2019)
Um Sicherheit und Umweltverträglichkeit von Straßen- bzw. Kraftfahrzeugen zu gewährleisten, werden an die Gestaltung der Fahrzeuge technische Anforderungen gestellt. Es gibt Anforderungen durch den Gesetzgeber, die erfüllt werden müssen, um ein Fahrzeug in den Verkehr bringen zu dürfen. Darüber hinaus bestehen herstellerinterne Anforderungen an das Produkt, die über das vom Gesetzgeber geforderte Maß hinausgehen, um den Kundenwünschen und der Firmenphilosophie zu genügen. Und als dritter Punkt stellen auch Verbraucherschutz-Organisationen Kriterien auf, anhand derer sie die Eigenschaften der auf dem Markt befindlichen Fahrzeuge bewerten und die Fahrzeuge eingruppieren, was dann der Kundeninformation dient. Auch diese Anforderungen gehen über die des Gesetzgebers hinaus. Das Setzen der gesetzlichen Mindestanforderungen ist für die Fahrzeugtechnik mittlerweile jedoch nicht mehr einzelnen Staaten überlassen. Vielmehr sind die für die Genehmigung von Fahrzeugtypen einzuhaltenden Bedingungen international harmonisiert: Für die EU sind dies EU-Richtlinien oder EU-Verordnungen, die von der Europäischen Kommission in Brüssel vorgeschlagen werden. Für über die EU hinausgehende Staaten bzw. Regionen sind dies unter anderem Regelungen der UN, erstellt von der UN-Wirtschaftskommission für Europa (UNECE) in Genf.
