TravelDistance

TravelDistance[{loc1,loc2,…}]

loc1から loc2，…までの移動がどれほどの距離になるかを返す．

詳細とオプション

例題

すべて開く すべて閉じる

例  (1)

推定総移動時間を計算する：

Wolfram Language code: TravelDistance[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]

スコープ  (4)

2つの地理位置間の移動距離：

Wolfram Language code: TravelDistance[{Entity["City", {"London", "GreaterLondon", "UnitedKingdom"}], Entity["City", {"Berlin", "Berlin", "Germany"}]}]

GeoPositionオブジェクトを使って場所を定義する：

Wolfram Language code: TravelDistance[{GeoPosition[{40.11, -88.24}], GeoPosition[{41.84, -87.69}]}]

いくつかの場所を通る移動距離を計算する：

Wolfram Language code: TravelDistance[{Entity["City", {"Lima", "Lima", "Peru"}], GeoPosition[{-14.06, -75.75}], Entity["City", {"Arequipa", "Arequipa", "Peru"}], Entity["City", {"Cusco", "Cusco", "Peru"}]}]

場所を住所として指定する：

Wolfram Language code: TravelDistance[{"100 Trade Center Drive, Champaign, Illinois, US", Entity["City", {"Chicago", "Illinois", "UnitedStates"}]}]

オプション  (2)

TravelMethod  (1)

TravelDistanceは，デフォルトの移動メソッドして"Driving"を使う：

Wolfram Language code: TravelDistance[{Entity["Building", "EmpireStateBuilding::h583b"], Entity["Museum", "MuseumOfModernArt::nfkn8"]}, TravelMethod -> "Driving"]

代りに"Walking"を使う：

Wolfram Language code: TravelDistance[{Entity["Building", "EmpireStateBuilding::h583b"], Entity["Museum", "MuseumOfModernArt::nfkn8"]}, TravelMethod -> "Walking"]

UnitSystem  (1)

デフォルトの単位系は$UnitSystemで与えられる．これには，通常はユーザの所在地によって決定される．この場合は"Imperial"が使われる：

Wolfram Language code: TravelDistance[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]

結果の単位系を指定する：

Wolfram Language code: TravelDistance[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}, UnitSystem -> "Metric"]

特性と関係  (2)

2つの場所の間の推定移動距離を計算する：

Wolfram Language code: TravelDistance[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]

これは，TravelDirectionsを使って計算することもできる：

Wolfram Language code: TravelDirections[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}, "TravelDistance"]

TravelDirectionsDataオブジェクトの特性としても計算できる：

Wolfram Language code: TravelDirections[{Entity["City", {"Miami", "Florida", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]
Wolfram Language code: %["TravelDistance"]

連続する位置のペア間の距離を計算する：

Wolfram Language code: list = {Entity["City", {"Madrid", "Madrid", "Spain"}], Entity["City", {"Paris", "IleDeFrance", "France"}], Entity["City", {"Vienna", "Vienna", "Austria"}], Entity["City", {"Berlin", "Berlin", "Germany"}]};
Wolfram Language code: TravelDistanceList[list]//Normal

上記はPartitionとTravelDistanceを計算して得ることもできるが，そうすると効率が悪い：

Wolfram Language code: TravelDistance@@@Partition[list, 2, 1]
