C-ITS Relevant Critical Vehicle-to-Vehicle Accident Scenarios for Accident Analysis

Abstract

The relevance of scientific investigations, whether simulative or empirical, is strongly related to the environment used and the scenarios associated with it. Within the field of cooperative intelligent transport systems, use-cases are defined to describe the benefits of applications. This has already been conducted in the available safety-relevant Day 1 applications longitudinal and intersection collision risk warning through the respective technical specifications. However, the relevance of traffic scenarios is always a function of accident severity and frequency of a retrospective consideration of accident databases. In this study, vehicle-to-vehicle scenarios with high frequency and/or severe personal injuries are therefore determined with the help of the CISS database and linked to the use-cases of the safety-relevant Day 1 applications. The relevance of the scenarios thus results on the one hand from the classical parameters of retrospective accident analysis and on the other hand from the coverage by the named vehicle-to-x applications. As a result, accident scenarios with oncoming vehicles are the most relevant scenarios for investigations with cooperative intelligent transport systems. In addition, high coverage of the most critical scenarios within the use-cases of longitudinal and intersection collision risk warning is already apparent.

Impact of Partially Automated Driving Functions on Forensic Accident Reconstruction: A Simulator Study on Driver Reaction Behavior in the Event of a Malfunctioning System Behavior

“…It can be assumed this leads to a significant change in the driver's reaction behavior. In [11], the period from 15 s to the recurring request to touch the steering wheel also varied, which is inconsistent with actual system behavior [36]. At the same time, an increasing "out-of-the-loop" effect can decrease the driver's attention to the driving situation.…”

“…This allows for realistic driving scenarios with all six degrees of freedom to be dynamically simulated with the aid of four projectors. The technical data of the simulator and details on the hardware and software setup can be found in [42]. The suitability of the driving simulator for conducting scientific studies has often been demonstrated in recent years [43][44][45].…”

“…The study lasted approximately 60 min for each subject. Since another study was conducted in parallel to this study with the same subjects [42], the test blocks were conducted alternately with randomly assigned subjects to avoid a systematic bias of the results due to the study design. The University of Žilina ethics committee reviewed and approved the study before it was conducted.…”
