Abstract:This study explores the potential safety implications of two heavy-truck platooning concepts. The findings summarized in this final report are intended to assist with identifying and assessing potential safety hazards and risks associated with concept heavy truck platooning systems. This study reviewed heavy truck platooning systems and concepts under development. After the market assessment, two “reference” (or prototypical) systems representing alternative platooning concepts were identified as a basis for hazards analysis. The study included creating a list of potential hazards, and then categorizing them according to their risks as specified by the ISO 26262 Road Vehicles – Functional Safety standard. A safety of the intended function analysis was also performed guided by the ISO 21448 Road Vehicles – Safety of the Intended Functionality standard. Finally, a fault tree analysis was performed on selected hazards identified in the hazards analysis.
