We propose a new map retrieval method within a Snake-Shaped Region (SSR) along a driving route corridor. We considered four techniques. The first is by simplification of the SSR. The second is by dividing the SSR with cells of a spatial search index. The third is by split distributions for an efficent transfer. Finally, the forth is multilayer distributions for route deviations. We have developed a prototype based on these proposed methods. The prototype uses United States road map data, which amounts to approximately 12-million road features, and provides route guidance information. Even in an urban area, we managed to provide an approximately 200-mile route area of guide information within 10 seconds.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"103","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"93","bibliographicIssueDates":{"bibliographicIssueDate":"2007-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(TOD34)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
