boolean
將這個路線控點標示為里程碑，而不是停靠點。對於要求中的每個非透過路線控點，回應會在 legs 陣列中附加一個項目，提供行程中該路段的停靠站詳細資料。如果您想讓路線經過這個路線點而不停靠，請將這個值設為 true。透過路線控點，系統不會將項目加入 legs 陣列，但會讓路線經過路線控點。您只能在為中繼的路線控點設定此值。如果您在終端路線控點設定這個欄位，要求就會失敗。如果將 ComputeRoutesRequest.optimize_waypoint_order 設為 true，則這個欄位無法設為 true；否則要求失敗。

For each non-via waypoint in the request, the response appends an entry to the [`legs`](/maps/documentation/routes/reference/rest/v2/TopLevel/computeRoutes#Route.FIELDS.legs) array to provide the details for stopovers on that leg of the trip. Set this value to true when you want the route to pass through this waypoint without stopping over. Via waypoints don't cause an entry to be added to the `legs` array, but they do route the journey through the waypoint. You can only set this value on waypoints that are intermediates. The request fails if you set this field on terminal waypoints. If `ComputeRoutesRequest.optimize_waypoint_order` is set to true then this field cannot be set to true; otherwise, the request fails. |\n| `vehicleStopover` | `boolean` Indicates that the waypoint is meant for vehicles to stop at, where the intention is to either pickup or drop-off. When you set this value, the calculated route won't include non-`via` waypoints on roads that are unsuitable for pickup and drop-off. This option works only for `DRIVE` and `TWO_WHEELER` travel modes, and when the `locationType` is [`Location`](/maps/documentation/routes/reference/rest/v2/Location). |\n| `sideOfRoad` | `boolean` Indicates that the location of this waypoint is meant to have a preference for the vehicle to stop at a particular side of road. When you set this value, the route will pass through the location so that the vehicle can stop at the side of road that the location is biased towards from the center of the road. This option works only for `DRIVE` and `TWO_WHEELER` [`RouteTravelMode`](/maps/documentation/routes/reference/rest/v2/RouteTravelMode). |\n| Union field `location_type`. Different ways to represent a location. `location_type` can be only one of the following: ||\n| `location` | `object (`[Location](/maps/documentation/routes/reference/rest/v2/Location)`)` A point specified using geographic coordinates, including an optional heading. |\n| `placeId` | `string` The POI Place ID associated with the waypoint. |\n| `address` | `string` Human readable address or a plus code.
