“…The risk of death at each road crossing is rather small (1 in 300 million) 6 , and thus it is difficult for any study to claim it fully addresses the potential danger. We acknowledge that our participant sample size and demographic distribution may limit generalizability of our findings (prior work identified location-based differences in road crossing behaviour [8]).…”

“…Context also plays a role in crossing behaviour. Currano et al [8] highlight the effect of location: pedestrians in a large city are more likely to cross in front of oncoming vehicles than in a smaller city. The impact of other pedestrians has also been studied [14,27].…”

“…Over recent years, there have been several high-profile studies which have utilised a Wizard-of-Oz (WoZ) approach to simulate an AV [13][14][15]. In these on-road studies, the so-called 'Ghost Driver' [13] is typically concealed within a bespoke seat-suit thereby ensuring they cannot be seen by pedestrians and other road users if they make a cursory glance.…”

We employed the 'Ghost Driver' methodology to emulate an autonomous vehicle (AV) and explored pedestrians' (n=520) crossing behaviour in response to external human-machine interfaces (eHMIs). Three eHMI designs were created to replace absent pedestrian-driver communication; each had different anthropomorphic elements and were identified as 'explicit', 'implicit' and 'low' to reflect the conspicuity of anthropomorphism. They were displayed on an LED matrix and strip mounted to the front of a Nissan Leaf vehicle, which was driven around the University campus over 5 days. Video analysis highlighted differences in pedestrians' behaviour, with the explicit anthropomorphism eHMI extending crossing time and attracting more visual attention. Additionally, some pedestrians continued to use gestures, ostensibly to indicate their intention to cross or to thank the vehicle, despite the absence of a visible driver. While preliminary findings support the application of anthropomorphism in AV-pedestrian communications, further research will explore designs in more controlled, experimental settings.

“…[9]. On-screen guidance should furthermore be scalable and work in urban traffic scenarios, given that a majority of pedestrian-related accidents happen in urban areas [73] and pedestrians tend to be less patient in bigger cities [14]. We created several design sketches and evaluated them in a focus group with four human-computer interaction experts (all male, 25 to 32 years, mean: 29.25 years, SD: 2.98).…”

Using a smartphone while walking in urban traffic is dangerous. Pedestrians might become distracted and have to split their attention between traffic, walking and using the mobile device. The increasing level of automation in vehicles introduces novel challenges and opportunities for pedestrian-vehicle interaction, e.g external displays attached to automated vehicles. However, these approaches are hardly scalable and fail to provide clear information in a multiuser environment. We investigate whether a smartphone app could provide individual guidance to enhance pedestrian safety in future traffic. To this end, we tested three app concepts in a user study (N=24) and found that on-screen guidance increases the frequency of successful crossing decisions significantly. In addition, all participants indicated that they would use the proposed system, preferably with an unobtrusive colored bar indicating the safest crossing decision in real-time.
