“…This study of preventing collision uses the CEDATU (Central Database for In-Depth Accident Study) road accident database [40,41] as a source of data. The CEDATU includes about 4500 accidents that resulted in either personal injury (fatal, severe or minor) or property damage only.…”

With the increasing complexity of automated driving features, it is crucial to adopt innovative approaches that combine hardware and software to validate prototype vehicles in the early stages of development. This article demonstrates the effectiveness of a Vehicle-in-the-Loop (ViL) testbed in conducting dynamic tests of vehicles equipped with highly automated driving functions. The tests are designed to replicate critical driving scenarios from real-world environments on the ViL testbed. In this study, the Apollo platform is utilized to develop an automated driving function that can perceive the surrounding traffic in a virtual environment and generate feasible trajectories. This is achieved with the help of a multibody simulation platform. The control commands from the simulated driving function are then transmitted to the real vehicle to execute the planned action. The results demonstrate that critical traffic scenarios can be replicated more safely and repeatedly on the ViL testbed. Meanwhile, the Apollo-based driving function can effectively and comfortably cope with critical scenarios. Importantly, this study marks a significant milestone for the Apollo platform as it is implemented in a real-time system and tested on a ViL testbed.

“…The accident analysis conducted within the rISEr project [1] highlights for example that even though only 10% of the total number of accidents are single vehicle accidents (typically associated to rOr crashes), the proportion of single vehicle events increase up to 45% when only fatal accidents are considered. The segment of fatalities resulting from this accident type varies from within European countries, but single vehicle accident fatalities constitute approximately one third of annual road fatalities [2].…”

collisions between vehicles leaving the road and unforgiving roadside objects such as trees, poles, road signs, etc. constitute a major road safety issue. On the Austrian road network, approximately 7.500 injury crashes occur every year due to run-off-road (rOr) manoeuvres (i.e. 20% of all injury crashes on public roads), contributing 35% to fatalities and 25% to serious injuries. Vehicle restraint systems (VrS) such as guardrails, concrete barriers, terminals or crash attenuators play a decisive role in mitigating the consequences of rOr crashes. unfortunately, most national road administrations (NrA) do not have a centralized data management, while geo-referenced information on VrS and their safety-related attributes are also not available as digitized data. researchers from the AIT have developed a novel approach to investigate, classify and evaluate VrS by means of image data processing, towards providing a comprehensive VrS inventory. The information obtained can be used for benefit-cost-analyses, road safety inspections and the evaluation of the effectiveness of different vehicle restraint systems.

“…The guardrail is a protective element that is placed at the sides of roads to ensure the safety of persons in case of loss of control of the vehicle. Today the design and the placement of guardrails on the roads are carried out taking into account several factors such as the potential crash severities, traffic exposure, and costs of treatment [19,35].…”
