External Human-Machine Interfaces can fail! An examination of trust development and misuse in a large CAVE-based pedestrian simulation environment

<b>Aim:</b> In this study, we aimed to investigate pedestrians’ trust, crossing behaviour, and misuse of an automated vehicle (AV) equipped with an external human-machine interface (eHMI). We hypothesized that participants’ trust would drop to a low level when the eHMI fails (i.e., the eHMI turns on, but the vehicle does not brake), followed by...

External HumanMachine Interfaces on Autonomous Vehicles: The Effects of Information Type on Pedestrian Crossing Decisions

Traffic is a self-organising, regulated system, but there are several ambiguous situations where no rules apply. In such situations, communication is important in order to achieve a smooth traffic flow and a safe situation. However, in the majority of traffic conflicts, adequate coordination between road users is lacking. Communication is...

The Detection of Pedestrian Crossing Behaviour

The pedestrian is regarded to be one of the most vulnerable road users. Non-verbal communication between drivers and pedestrians seems to play an important role in the mitigation of collisions. The emergence of autonomous vehicles in traffic in the near future presses the need to investigate objective measures related to pedestrian crossing...
