Information Presentation in Autonomous Shuttle Busses: –What and How?

This paper addresses what kind of information users need when driving in an autonomously shuttle and how this information is communicated. This was investigated in two studies with participants in the age-range of 23–25 years using online focus groups. Results showed that both groups rely on the “safety driver” because it supports the feeling of security. Concerning the possibilities of transmission via different human-machine-interfaces, the participants agreed in both studies that the type of information and its transmission should be similar to that used in today's public transport. Differences between the two studies arose in the discussion about the presentation of technical information. One group preferred that technical information, including the explanation of how the shuttle works and real-time sensor data of what the autonomous shuttle is detecting, be shown by default. On the contrary, the other group only preferred this information on request by the passengers. Furthermore, participants explained that such information could increase insecurity as it could be too detailed and might overwhelm passengers. Both groups agreed that providing some extra information for reducing concerns is helpful. One aspect for overcoming negative feelings in the shuttle was the idea that more infotainment options, such as showing Points of Interest, can elicit positive feelings during the ride and this in turn can decrease potential fear or trust issues with autonomous shuttles.
