Safety Case for Autonomous Trucks (SCAT)

• To aim for market introduction and sustainability of automated vehicles requires technology innovation towards safe products and policy innovation to enable testing on open roads and type approvals. Further, it needs an enabling infrastructure to provide reliable connectivity, business models and increased public acceptance of this new technology. The project SCAT – Safety Case for Autonomous Trucks contributed to this transmission by looking at new policy strategies and system tests to prove how to handle vehicles when introducing this new technology safely. Main objective of the project was to investigate more systematically – from a legal and technical perspective – how to safely operate remote controlled vehicles in mixed traffic and with higher velocity. A safety case for the selected traffic environment has been described and explorative tests have been performed at the AstaZero test site in Sweden. This allowed us to investigate limiting parameters and stress testing the system's boundaries under real conditions with higher velocity – before the actual demo will be run. With regards to policy, we addressed which obligations drivers and road users have according to today's regulations and which of those may need to be handled through technological development, but also through adaptation of legislation in terms of new roles, tasks, and liability when a vehicle is driven automatically. We looked also at if and how these issues are treated in national and international legislation, in Sweden, France and the USA. What we learned from exploring the safety case contributes to practical improvement, theory building and recommendations on how to safely operate the vehicles. Together the partners have developed an approach to advanced argumentation for safety. In our approach, we combined policy lab methodology and an investigation of the technical safety aspects that helped to identify gaps and tests for improved safety. The approach provides step-by-step guidance before future trials. The project was running from October 2020 until September 2022. The consortium consisted of the partners AstaZero, Einride, Ericsson, RISE (coordinator), Telia as well as reference partners in France and the USA.
