传单路由机器没有给出最佳路线（到目前为止）

Question

尝试在传单地图上显示路线时遇到问题：

  L.Routing.control({
  router: L.Routing.mapbox(''),
  profile:"mapbox/driving",
  addWaypoints:false,
  waypointMode:'snap',
  routeWhileDragging: true,
  show:false,
  fitSelectedRoutes:false,
  plan:false,
  draggableWaypoints:false,
  lineOptions:{
    styles:[ {color: 'black', opacity: 0.8, weight: 6}, {color: 'red', opacity: 1, weight: 2}]
      },
  waypoints: [
    L.Routing.waypoint(L.latLng(28.6114741,77.2112497),"New Dehli"),
    L.Routing.waypoint(L.latLng(30.7304186,76.7789926),"Chandigarh"),
    L.Routing.waypoint(L.latLng(31.1047637,77.1717752),"Shimla"),
    L.Routing.waypoint(L.latLng(31.4493988,77.629702),"Rampur"),
    L.Routing.waypoint(L.latLng(31.9755409,78.5961753),"Changoa"),
    L.Routing.waypoint(L.latLng(32.2251899,78.0610693),"Kaza"),
    L.Routing.waypoint(L.latLng(32.4513357,77.860656),"Hanse"),
    L.Routing.waypoint(L.latLng(32.4386919,77.7497997),"losar gompa"),
  ],

}).addTo(map);

在第 7 个航路点（Hanse），路线正在掉头，增加一千公里到达距离只有几公里的第 8 个点。

这里发生了什么？我想不通。欢迎任何帮助！

欢迎来到 SO！

这可以通过 OSMR 服务而不是 Mapbox 重现：

var map = L.map("map").setView([32.4513357, 77.860656], 10);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

L.Routing.control({
  //router: L.Routing.mapbox(''),
  //profile: "mapbox/driving",
  addWaypoints: false,
  waypointMode: 'snap',
  routeWhileDragging: true,
  show: false,
  fitSelectedRoutes: false,
  plan: false,
  draggableWaypoints: false,
  lineOptions: {
    styles: [{
      color: 'black',
      opacity: 0.8,
      weight: 6
    }, {
      color: 'red',
      opacity: 1,
      weight: 2
    }]
  },
  waypoints: [
    /*L.Routing.waypoint(L.latLng(28.6114741, 77.2112497), "New Dehli"),
    L.Routing.waypoint(L.latLng(30.7304186, 76.7789926), "Chandigarh"),
    L.Routing.waypoint(L.latLng(31.1047637, 77.1717752), "Shimla"),
    L.Routing.waypoint(L.latLng(31.4493988, 77.629702), "Rampur"),
    L.Routing.waypoint(L.latLng(31.9755409, 78.5961753), "Changoa"),

    L.Routing.waypoint(L.latLng(32.4513357, 77.860656), "Hanse"),
    L.Routing.waypoint(L.latLng(32.4386919, 77.7497997), "losar gompa"),
  ],

}).addTo(map);

#map {

OSM 数据库似乎认为您的到达点附近存在“障碍”障碍物（“losar gompa”）：

如果这种类型的障碍物不能被汽车穿越，那就可以解释为什么路由器会选择另一条（很长的……）路线。

如果您认为这个障碍不再存在，请随时在 OpenStreetMap 上创建一个帐户并编辑地图！ Mapbox 路由器很有可能使用 OSM 数据，因此您的修改将在一段时间后反映在 Mapbox 中。
