However, passengers who use the bus usually feel the stress when the bus is crowded by Irregular events. Moreover, it is necessary for a bus driver to check location of passengers for safety in the bus without preventing driving operation. The camera image analysis is usually used for checking crowded bus situation, however, the method has a problem about the privacy. In this study, we have used BLE and sound as feature of crowded situation because BLE and sound are shielded to the body of the people. In this paper, we evaluated the accuracy of these methods by the experiment for estimating crowded situation in the room of assuming the bus.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-12-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"14","bibliographicVolumeNumber":"2015-DPS-165"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":146472,"updated":"2025-01-20T17:57:30.548108+00:00","links":{},"created":"2025-01-19T00:21:55.971817+00:00"}
