TravelDistanceList

TravelDistanceList[{loc1,loc2,…,locn}]

リスト{TravelDistance[loc1,loc2],…,TravelDistance[locn-1,locn]}を返す．

詳細とオプション

  • TravelDistanceList[{loc1,…,locn}]における位置 lociは，度を単位とした{lat,lon}ペア，GeoPositionオブジェクト，地理Entityオブジェクト，あるいは他の任意の位置指定で与えることができる．
  • 結果は長さを単位としたQuantityArrayオブジェクトとして返される．
  • 位置の入力リストの長さが n のとき，結果の距離のリストの長さは n-1である．
  • TravelDistanceListは，以下のオプションを取る．
  • TravelMethod "Driving"想定される移動手段
    UnitSystem $UnitSystem出力に使用する単位系

例  (1)

都市間の連続する走行距離のリスト：

Wolfram Language code: TravelDistanceList[{Entity["City", {"MexicoCity", "DistritoFederal", "Mexico"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"Toronto", "Ontario", "Canada"}]}]

QuantityArrayオブジェクトを標準形に変換する：

Wolfram Language code: Normal[%]

スコープ  (2)

入力はGeoPositionオブジェクトのリストとして与えることができる：

Wolfram Language code: TravelDistanceList[{GeoPosition[{-12.04, -77.03}], GeoPosition[{-33.46, -70.64}], GeoPosition[{-34.61, -58.37}]}]//Normal

異なる位置指定を混ぜることができる：

Wolfram Language code: TravelDistanceList[{Entity["City", {"Lima", "Lima", "Peru"}], GeoPosition[{-33.46, -70.64}], Entity["City", {"BuenosAires", "BuenosAires", "Argentina"}]}]//Normal

オプション  (2)

TravelMethod  (1)

返される距離は特定の移動方法に最適化された道順に対応する．TravelDistanceListはデフォルトで"Driving"を使う：

Wolfram Language code: Table[{tm, TravelDistanceList[{Entity["City", {"NewYork", "NewYork", "UnitedStates"}], Entity["City", {"Philadelphia", "Pennsylvania", "UnitedStates"}], Entity["City", {"Washington", "DistrictOfColumbia", "UnitedStates"}]}, TravelMethod -> tm]//Normal}, {tm, {"Driving", "Biking", "Walking"}}]//Grid

UnitSystem  (1)

結果のデフォルトの単位は$UnitSystemの値で決定される：

Wolfram Language code: $UnitSystem
Wolfram Language code: TravelDistanceList[{Entity["City", {"SanFrancisco", "California", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]//Normal

別の単位系に変える：

Wolfram Language code: TravelDistanceList[{Entity["City", {"SanFrancisco", "California", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}, UnitSystem -> "Metric"]//Normal

特性と関係  (3)

TravelDistanceListは，基本的に（はるかに高速ではあるが），SubsequencesとTravelDistanceを組み合せたものに等しい：

Wolfram Language code: locs = {Entity["City", {"SanFrancisco", "California", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}
Wolfram Language code: TravelDistance@@@Subsequences[locs, {2}]
Wolfram Language code: % == TravelDistanceList[locs]

TravelDistanceListで返される距離の和はTravelDistanceが返す距離の和と同じである：

Wolfram Language code: TravelDistance[locs] == Total[TravelDistanceList[locs]]

TravelDistanceListは道路の距離を返す．GeoDistanceListは測地距離を返す：

Wolfram Language code: TravelDistanceList[{Entity["City", {"SanFrancisco", "California", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]//Normal
Wolfram Language code: GeoDistanceList[{Entity["City", {"SanFrancisco", "California", "UnitedStates"}], Entity["City", {"Chicago", "Illinois", "UnitedStates"}], Entity["City", {"NewYork", "NewYork", "UnitedStates"}]}]//Normal

TravelDistanceList[{loc}]は空リストを返す：

Wolfram Language code: TravelDistanceList[{Here}]

TravelDistanceList[{}]は定義されない：

Wolfram Language code: TravelDistanceList[{}]
