Purpose and goal

To become widely used on public roads, automated vehicles (AVs) will need to be trusted and gain societal acceptance - something that will be greatly affected by the ability of the AVs to safely and efficiently interact with other road users. These external interactions have until recently been largely unexplored, even though a few studies have been conducted during the last 3-4 years, solely focusing on passenger cars. The project will investigate how trust and acceptance of heavy AVs can be created and maintained via design of interaction principles between AVs and other road users.

Expected results and effects

The expected results include: a) knowledge on how heavy AVs interact with other road users, b) guidelines on what, how and when to communicate to/from heavy AVs, c) interface prototypes of different fidelity levels, d) a mixed methodology framework for evaluation of external interactions in different settings, and e) one licentiate thesis focusing on safety, efficiency and experience. The project is the first to address the topic in the context of heavy AVs and will provide unique knowledge to industry and research community.

Planned approach and implementation

The project will create a holistic perspective and consider interactions with different road users and in various scenarios. A series of design and user studies will be conducted utilizing a mixed-methodology approach. The work is divided in six work-packages: 1) Project lead, dissemination, standardization, 2) Selection and specification of use cases, 3) Understanding current and future interactions, 4) Design and implementation of external interaction concepts, 5) Development of evaluation methodology, 6) Evaluations of concepts and analysis.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
