About this presentation • Some basics about human (or interpersonal) communication Automated Driving and the effects on • Short information about a study on automated driving and the effects on communication in communication in road traffic road traffic with a special focus on VRU • Some selected results of expert interviews Karin Ausserer & Ralf Risser • Some questions to be tackled in oncoming research Signals What is communication? Different ways to communicate: = act and react Eye contact, hand signals, = observe and head movements, facial be observed expressions, gestures, …. � often an automatic & unreflected process “One cannot not communicate” (Watzlawik 1969) � The same signals may have different functions and meanings depending on the context Body language The meaning of signals Head movements and posture might stand for Hand signals by walkers might mean • I will move on • I stop • I will stop • I will move on • I have priority • thank you • … • … As well, without moving your hands With only slight differences in body posture, � One could write a Depending on the context dictionary

Study Approach What did the experts say • 15 expert interviews (thinking) • Literature study • 15 expert interviews (all over Europe) • Traffic observation in public spaces • 2 Focus Group Interviews • Online expert survey (n= 50) Experts` predictions How will communication change? • 78%: human “Automation is at the moment all about car drivers…you have to ensure that there are benefits or at least no threats to other groups.” communication will become less (Psychologist, Czech Republic) important • 58%: automated cars will be able to communicate with vulnerable road users • 44%: cars will be able to decode postures and gestures of vulnerable road users Effects according to experts Challenges & open questions Majority of experts say: • Labelling: Is it necessary to label automated cars? • traffic safety will increase (for healthy adults) due to • Information: What kind of information should be automation given? How to transfer information? • children and very old people will have more problems • Education: How are road users educated with • standardisation of digital communication important for respect to automated cars? traffic safety: e.g. light signals that indicate that car will stop at pedestrian crossing • Indicators: What kind of indicators are used to • pedestrians to be equipped with chips in order to be measure success or undesirable developments? detected by automated cars? Majority � not desirable! • Standards: What kind of standards should be • strict separation of pedestrians (e.g. fences) not desirable predefined? either but to be considered for traffic safety reasons
