absent in autonomous vehicles, concerns arise regarding insufficient communication between the vehicle and pedestrians, leading to overtrust or distrust and hindering safe and smooth traffic flow. To address this, we propose estimating the trust level of pedestrians towards vehicles by observing pedestrian behavior and adjusting this trust level through vehicle control and information presentation. Following experiments conducted in VR environments to estimate trust levels, this study aims to estimate trust levels in real-world settings. In a scenario simulating a single-lane, unsignalized pedestrian crossing, vehicles approach while decelerating, and pedestrians record their trust levels towards the approaching vehicles in three levels at various intervals, both before and during the crossing. Pedestrian and vehicle behaviors are captured using ground and onboard cameras. Deep learning (LSTM) is employed to estimate trust levels using features such as distances between pedestrians and vehicles extracted by YOLOv5 and pedestrian skeletal coordinates extracted by OpenPose. Results show overall accuracies of 77% and 64% for pre-crossing and crossing phases, respectively, revealing discernible trends in pedestrian behavior for both correct and incorrect estimations.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告知能システム（ICS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2024-ICS-214"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233582,"links":{}}
