Traffic accident analysis using EDR data: a case study of a multicollision event

Abstract

This paper focusses on the importance of using Event Data Recorder (EDR) data in the reconstruction of traffic accidents. It presents a case study of a highway accident in which aggressive overtaking led to a series of collisions between three vehicles. Although the speed recorded at certain moments was not accurate due to vehicle skidding, the EDR data allowed confirmation of key manoeuvres and movements of the vehicles prior to the collision. The paper highlights the importance of EDRs in accident analysis, where they helped reconstruct the drivers’ manoeuvres and decisions, contributing to the elucidation of the causes of the accident. The mandatory introduction of EDRs in new vehicles from 2024 is an important step towards better crash analysis and improved road safety.
