Presentation of modern accident reconstruction procedures - Case study

Abstract

Nowadays, the reconstruction of traffic accidents utilizing current vehicle technology presents new challenges for professional accident analysis. The downloading and reading of data stored in vehicles and the professional interpretation of these data is becoming important for full interpretation of the accident reconstruction. But this data cannot be interpreted without the use of separate mathematical analysis and comparison to the physical scene data for the analysis of traffic accidents. In this paper, the process is discussed of an accident resulted by a Toyota Yaris passenger car’s stability loss of control that resulted in a traffic accident. During the analysis, we will use data from the electronic EDR (Event Data Recorder) placed in the vehicle, as well as data recorded by in the auxiliary equipment (on-board camera). In determining the most likely accident process, account should be taken of the data obtained from other accident related devices as well as the GIS data for the environment. The paper details how data from different sources can be evaluated, how conflicting data can be reconciled and, how to resolve contradictions.
