 note = {人や車いす利用者のためのナピゲーションを行うためには，従来の通路単位の位置推定ではなく，通路の両側の歩道単位の位置推定が必要である． しかし，屋外で利用する衛星測位は平均水平誤差が約 13m あり，特に高い建物が多い都心部 （アーバンキャニオン） では誤差が著しく増大し，測位結果のみから車道を挟む 2 つの歩道 （通路） のいずれを通行したかを判定することは難しい．そこで本論文では，進行方向に対する左右の衛星電波の受信状況から左右の建物状況を推定し，左右のいずれの通路を通行したのかを判定する方法を提案し，評価実験によりマップマッチングのみを用いる方法と比較して判定精度が 2 割向上することを示す．, In order to perform navigation for people and wheelchair users, it is necessary to estimate the location of the sidewalk units on both sides of the passage instead of the conventional location estimation of the passage unit. However, satellite positioning used outdoors has an average horizontal error of about 13 meter, and the error significantly increases in urban areas where there are tall buildings (urban canyons). In such a place, the accuracy of determining which of the two sidewalks (passages) sandwiching the road from the positioning results by satellites is greatly reduced. Therefore, in this paper, we propose a new method to estimate the state of the buildings on the left and right from the received signal strength of satellite on the left and right with respect to the traveling direction, and to determine which path on the left and right has passed. It shows that the determination accuracy is improved by 20% compared to the method using only map-matching.},
