Zusammenfassung: | To put a higher priority on presenting a target point which is more likely to be a target point when there are a plurality of target points as candidates.SOLUTION: When there are a plurality of extracted points extracted from a point database 1 by a search point 5 as target points F which satisfy a search condition, a search result output unit 4 sets an output priority on the basis of set route information stored in a route length database 2 and outputs information on the extracted points. The set route information includes information on a route length index which is larger when a length L of a set route previously set by a plurality of mobile bodies 10 is large than when the length L is small. The output priority is set to be higher in an extracted point with a higher route length index than in an extracted point with a lower route length index when the extracted point with a higher route length index and the extracted point with a lower route length index satisfy the search condition to the same degree.SELECTED DRAWING: Figure 1
【課題】候補となる対象地点が複数存在する場合に、目標地点となる可能性が高い対象地点が提示される優先度を高くする。【解決手段】検索条件に適合する対象地点Fとして検索部5により地点データベース1から抽出された抽出地点が複数存在する場合、検索結果出力部4は、経路長データベース2に記憶された設定経路情報に基づき出力優先度を設定して抽出地点の情報を出力する。設定経路情報は、複数の移動体10により過去に設定された設定経路の長さLが長い方が短いよりも高くなる経路長指標の情報を少なくとも含み、出力優先度は、検索条件への適合度が同じである場合に経路長指標の高い抽出地点の方が経路長指標の低い抽出地点よりも優先度が高くなるように、設定されている。【選択図】図1 |
