Methodological Study of the Driving Reliability and error Analysis Method (DREAM) (En metodologisk Studie av Ullykesgransking med Driving Reliability an Error Analysis Methods (DREAM))

摘要

The Driving Reliability and Error Analysis Method (DREAM) was used for further analyses of possible causes of 15 fatal road accidents that had been investigated by the Norwegian Public Roads Administration. It is concluded that DREAM is a useful supplement to currently used investigation methods for a thorough analysis of the precrash phase of road accidents. A complete analysis of road accidents requires that the DREAM be used in combination with methods for barrier analysis and for analyses of factors in the crash and postcrash phases, which may influence the severity of an accident. An important advantage of DREAM is the use of taxonomy of predefined general causal factors, which enables easy aggregation of results and comparisons across transport modes. Some modifications of the taxonomy were suggested on the basis of the analyses.
