In this paper, the walkability of a pedestrian moving past an autonomous mobile wheelchair is evaluated based on pedestrian measurements. In the past, the mainstream method was to use a subjective impression of a questionnaire to evaluate after an experiment. By evaluating the time series of the pedestrian's ease of walking, it is possible to reflect it on the appropriate control timing of the wheelchair. From the measured trajectory of the pedestrian, the temporal variation of the moving velocity vector is used as an index of the ease of passing, and the validity of the index is evaluated. An experiment was performed under three conditions with different predictability of the behavior of a pedestrian in a wheelchair, and the evaluation method based on the walking trajectory was verified. It was confirmed that became smaller. In addition, as a result of investigating the relationship with subjective walkability, a negative correlation was found, indicating the possibility that it was useful as an index of walkability.
