THE USE OF THE VEHICLE DEFORMATION INDEX AND COLLISION SPEED

The reasons for recording vehicle damage and the need for accurate estimates of collision and accident severity will be discussed at first. A review of the various methods that have been used for describing and recording vehicle damage will be made. The VDI will be shown to be an effective method of indexing vehicle damage so that vehicles with similar damage can be selected from a larger sample of accidents for further analysis. It will be stressed that the VDI cannot be used for meaningful analysis of accident severity. The limitations and consistency of the VDI assessments will be considered and illustrated by reference to a number of cases. A review of methods for describing accident severity will then be made. The concept of Equivalent Test Speed as a measure of accident severity will be discussed and the limitations of this method noted. Mention will be made of a method which is being developed by Peugeot/Renault for assessing accident severity. Finally it will be suggested that before more accurate assessments of collision speeds and accident severity can be made a considerable amount of experimental testing will have to be carried out to provide basic data. /Author/
