In urban areas, however, multipath propagation of GNSS signals degrades the accuracy of absolute positions and the deduced relative position. In our previous work, we suggested a cooperative relative positioning scheme to exploit correlated information, including reflected signals, in computing accurate relative position. In this paper, we evaluate the proposed scheme by using traffic simulation, with a case study of a right-turn scenario. Specifically, we evaluate both (i) its merit of improving relative positioning precision and (ii) its demerit due to the extra delay in exchanging measured information, and present its total effect in reducing the probability of collision accidents.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告高度交通システム（ITS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-02-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2014-ITS-56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":98777,"updated":"2025-01-21T12:19:17.784203+00:00","links":{},"created":"2025-01-18T23:44:57.263912+00:00"}
