Abstract
A confident interaction between pedestrians and automated vehicles will be a milestone in the acceptability of the use of these new vehicles. The automated vehicle should be able to offer the pedestrian a safe and non-uncertain street-crossing situation. The aim of the study was to perform an analysis of the activity of street-crossing, focusing on the decision-making in a natural environment.
The study was carried out with a sample of 20 participants A triangulation of Ergonomics methods (explicitation interview, video recordings and questionnaires) was conducted. Immediately after each last crossing, participants were invited to participate to an elicitation interview. In total, 73 street-crossings were described. Cognitive, perceptive activities and emotional feelings were identified, classified and analyzed.
The results highlight some different patterns of perceptive and cognitive activities between risky and non-risky decision-making. They show the complexity of the decision-making that cannot be reduced to a specific moment but constitutes a continuously updated process containing perception, action, cognition and social aspects. Moreover, a strong link with the emotional feelings is highlighted. In the context of the future interaction between the pedestrian and the automated vehicle, this study is a first step toward AVs which will have to anticipate and react appropriately to the street-crossing behavior of the pedestrians.
