A Methodology for Building Simulation Files from Police Recorded Accident Data (for ADAS Assessment)

European Institutions have reached an agreement for a new General Safety Regulation (GSR) that mandates the implementation of certain ADAS systems into new vehicles from 2022. This includes advanced emergency braking (AEB) and emergency lane keeping system (ELK), among other systems. In order to assess the performance of such systems, it is required to analyse the pre-crash phase of accidents, which can be done by means of simulating crashes. One widespread database of simulation input data is the GIDAS-PCM, which contains around 10,000 accident reconstructions from two German investigation areas (Dresden, Hannover) since the year 1999. This paper focuses on developing a novel method for generating the pre-crash phase based on police recorded accidents. This allows generating simulations of a large number of accidents. The simulation results can later be used in combination with ADAS models to understand the effectiveness of those systems.
