To estimate a facility where a vehicle is parked more accurately.SOLUTION: A vehicle position analyzer 30 includes: a storage unit 32 that stores position information including shapes of a plurality of facilities; a receiving unit 311 that receives continuous position information from a plurality of vehicles together with time information; a parking determination unit 312 that determines that the vehicle has been parked when the position information does not change for a predetermined time or more; and a stay determination unit 313 that estimates that the vehicle has stayed at the facility when a parking position of the vehicle is located within the shape of one facility stored in the storage unit 32, and determines that the vehicle has stayed at the facility when the shape of the facility is included by calculating whether the shape consisting of a circle with a predetermined radius centered on the parking position includes the shape of the facility when the parking position of the vehicle is not located within the shape of one facility stored in the storage unit 32.SELECTED DRAWING: Figure 4

    【課題】車両の駐車した施設をより正確に推定する。【解決手段】車両位置分析装置30は、複数の施設について施設の形状を含む位置情報を記憶する記憶部32と、複数の車両からの連続した位置情報を時刻情報とともに受信する受信部311と、位置情報に所定時間以上変化が無い場合に車両が駐車したと判定する駐車判定部312と、車両の駐車位置が記憶部32に記憶される1つの施設の形状内に位置する場合は車両が施設に滞在したと推定し、車両の駐車位置が記憶部32に記憶される1つの施設の形状内に位置しない場合は駐車位置を中心とする所定半径の円からなる形状が施設の形状を含むかを計算して、施設の形状を含む場合には車両が当該施設に滞在したと判定する滞在判定部313と、を備える。【選択図】図4
