Research question: In pursuit of Vision Zero towards traffic-related fatalities and injuries in Europe, the SECUR project (Safety Enhancement through Connected Users on the Road) was initiated in a Euro NCAP context. SECUR aims to study the potential of V2X communications to improve road safety. This paper illustrates the main European crash cases involving Passenger Cars as ego vehicles and their parameters. The following opponents were considered: Passenger Cars, Powered Two-Wheelers, Bicyclists and Pedestrians. Methods and Data Sources: An initial study of crashes at a high level was done to draw a general picture based on German (DESTATIS), French (BAAC) and European (CARE) crash databases. Then, an in-depth study was performed to select and define the SECUR crash cases and their characteristics. As part of this in-depth analysis a generic scenario catalog was developed, covering traffic crash situations, that the driver of a passenger might encounter. The most relevant scenarios regarding accidentology were determined providing the baseline to develop a test environment for a useful V2X-system. Based on the German Insurance Association crashes classification (GDV) and the German in-depth crash database (GIDAS), this catalog clusters all the GDV crash types in 28 categories, each crash being analysed from the perspectives of both participants and considering all different opponent types. The data of the most relevant 15 crash scenarios were provided through a GIDAS-based in-depth study, considering a set of 16 parameters. Results: According to the in-depth crash analysis, 15 out of 112 crash scenarios were identified as the most relevant ones regarding the number of Killed and Severely Injured (KSI) and the relevance of V2X. These 15 scenarios consider the 4 types of road users and cover 71% of all the KSI crashes from the catalog. Among them Straight Crossing Paths, Left Turn Across Path and Rear-End crash situations. The parameters study has shown that the most significant crash blackspot is at intersections with structural view obstruction. Discussion and Limitations: This study is subject to certain limitations. First, it is expected to be European representative, so the study was based on GIDAS and complemented with analyses of CARE and the in-depth database (IGLAD). However, the European representativity is still limited by the GIDAS-weighting upon CARE. Moreover, it is complex to draw conclusions for new vehicles as the current databases naturally include old information and are representative of a past context (vehicle without state-of-the-art safety systems). Therefore, in order to have a dataset more representative of the current context, crashes involving a vehicle without ESC were filtered out. Conclusion: The main crash cases to be ruled out for a significant road safety improvement through V2X are illustrated in this paper. The results have shown that significant white spots that are not addressed by ADAS due to physical sensor limitations (e.g., obstruction) remain. And it is precisely where V2X benefits sit, standalone or fused with current systems. SECUR results will feed Euro NCAP V2X introduction into the protocols and also further NCAP developments in other regions.
