Car ADR/EDR recorders – uncertainty of vehicle’s speed and trajectory determination
Journal Title: Archives of Transport - Year 2010, Vol 22, Issue 2
Abstract
One of the basic tasks of the accident reconstruction is to define values of parameters of participants of the accident before its actual occurrence. The assessment of correct behaviours is made and the court decides whether the accident participants are guilty or innocent. Therefore, the credibility of specific values is essential. The use of socalled accident recorders – EDR/ADR type of devices, as an alternative compared to classical methods for accidents reconstruction – has become more common over the past years. The paper includes basic notions related to his type of devices, describes potential sources of uncertainty of the car motion reconstruction results obtained on the basis of their records. The examples presented confirm their usefulness, however, they also indicate possible significant errors in the motion parameters assessment if simplified devices are used (where vehicle body lean movements in motion are not analysed).
