EDR is the equivalent of a black box that records a range of data from safety systems fitted to the vehicle in the seconds before, during and after a collision. The data helps provide information on the actions taken before a crash – which TRL says will be vital in understanding what an autonomous vehicle or its safety driver were doing just before an accident, for example.
Dean Beaumont, accident reconstruction consultant for TRL’s expert witness team, says EDR provides a more accurate investigation into road collisions, specifically regarding “causation and liability”.
“In the UK and EU, manufacturers are slowly allowing access to this data, but this only applies to a very small number of vehicles,” he continues. “Sharing of EDR data should not be placed above lives in serious and fatal collisions.”
