The development of automated vehicles (AVs) and their integration into traffic are seen by many vehicle manufacturers and stakeholders such as cities or transportation companies as a revolution in mobility. In future urban traffic, it is more likely that AVs will operate not in separated traffic spaces but in so-called mixed traffic environments where different types of traffic participants interact. Therefore, AVs must be able to communicate with other traffic participants, e.g., pedestrians as vulnerable road users (VRUs), to solve ambiguous traffic situations. To achieve well-working communication and thereby safe interaction between AVs and other traffic participants, the latest research discusses external human–machine interfaces (eHMIs) as promising communication tools. Therefore, this study examines the potential positive and negative effects of AVs equipped with static (only displaying the current vehicle automation status (VAS)) and dynamic (communicating an AV’s perception and intention) eHMIs on the interaction with pedestrians by taking subjective and objective measurements into account. In a Virtual Reality (VR) simulator study, 62 participants were instructed to cross a street while interacting with non-automated (without eHMI) and automated vehicles (equipped with static eHMI or dynamic eHMI). The results reveal that a static eHMI had no effect on pedestrians’ crossing decisions and behaviors compared to a non-automated vehicle without any eHMI. However, participants benefit from the additional information of a dynamic eHMI by making earlier decisions to cross the street and higher certainties regarding their decisions when interacting with an AV with a dynamic eHMI compared to an AV with a static eHMI or a non-automated vehicle. Implications for a holistic evaluation of eHMIs as AV communication tools and their safe introduction into traffic are discussed based on the results.

Automated vehicles (AVs) are sometimes considered a silver bullet for contemporary transport problems. For particular scenarios, the technology is believed to have many advantages, such as improving the accessibility of underserved populations. However, the technology may also lead to lesser consequences under other scenarios, with some simulations predicting increase in congestion as the modal split shifts towards automation. In any case, the mode choice shift will not be realised without the public acceptence of AVs. The public opinion towards the technology has not been fully explored, and particularly not in Iceland. This article focuses on the Icelandic results of a cross-national survey. 561 valid responses were recorded, considering attitudinal and stated-mode-choice questions and the responses then analysed as per the sample‘s socio-demographic attributes and compared to a similar survey performed in other european countries. The Icelandic public is generally more positive towards automated vehicles than other Europeans, however still skeptical. At the same time as AV passengers feel more safe than vulnerable road users in the vicinity of an AV, AV passengers also feel more safe with an AV supervisor inside the vehicle. It is uncertain whether people will use the vehicles for pick-up and drop-off of children. Respondents are generally more positive that their goods be transported in AVs instead of people. In spite of this, 70% of respondents were positive that the technology be tried in their neighborhood and 60% of respondents are positive towards trying the vehicles themselves. Further research is suggested in the outlook of the articles, based on indices and further metrics.
