用法說明

RouteParameters.travelMode函數(或屬性)的定義如下：

travelMode TravelMode

出行方式代表一種交通工具，例如駕車或步行。出行模式定義了車輛或行人的物理特征。

travelMode 參數的值是 JSON 對象，其中包含您的服務支持的出行模式的設置。要獲得支持的出行模式，請執行retrieveTravelModes 操作。您可以使用以下表單請求檢索出行模式：https://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World/retrieveTravelModes?f=json

例子：

// Display the fastest walking time route between two existing graphics.
const apiKey = "<your-api-key>";
const url = "https://route-api.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World";

// Obtain the routing service's description. The description contains all preset travel modes.
const serviceDescription = await networkService.fetchServiceDescription(url, apiKey);

// Find the named travel mode called "Walking Time".
const { supportedTravelModes } = serviceDescription;
const travelMode = supportedTravelModes.find((mode) => mode.name === "Walking Time");

// Construct the route parameter object.
const routeParameters = new RouteParameters({
  apiKey,
  stops: new FeatureSet({
    features: view.graphics.toArray()
  }),
  returnDirections: true,
  travelMode
});

// Solve the route and add the path representing the fastest walk path to the map.
const routeContainer = await route.solve(url, routeParameters);
for (const routeResult of routeContainer.routeResults) {
  const { routeLayer } = routeResult;
  routeLayer.symbol = {
    type: "simple-line",
    color: [5, 150, 255],
    width: 3
  };
  view.graphics.add(routeLayer);
}
