User-centered design within the context of automated driving in trucks – guideline and methods for future conceptualization of automated systems

Abstract

The monotony of moving in queues enhances truckers´ sleepiness and the danger of micro sleep, which put a serious risk on traffic safety. The research project TANGO aims at overcoming these risks by developing an Attention and Activity Assistance system (AAA). The AAA shall enable truck drivers to engage in non-driving-related activities during automated driving phases (up to SAE level 3), but keep them alert for tasks (monitoring or take-over) nevertheless. Throughout the project, numerous user studies have led to a great gain of knowledge about the users’ needs and design requirements concerning an automated system. For the purpose of an easier accessibility of this knowledge for future research, a guideline will be developed that covers both design guidance as well as a review of applied methods. The main scope of this paper focuses on the methodical process of developing the guideline.
