De forma predeterminada, el método Compute Routes de la API de Routes calcula una ruta a través de varias paradas, llamadas puntos de referencia de parada, en el orden en que las proporcionas.
Puedes hacer que la API de Routes optimice la ruta proporcionada reordenando las paradas en un orden más eficiente. La optimización de puntos de referencia optimiza el tiempo de viaje, pero también considera otros factores, como la distancia y la cantidad de giros, cuando decide qué ruta es la más eficiente.
Cómo optimizar los puntos de referencia
Asegúrate de que ninguno de los puntos de referencia de la ruta tenga via establecido en true, por ejemplo: {"address": "Clare,SA", "via": true}. Para obtener más información sobre los puntos de referencia intermedios, consulta Cómo especificar puntos de referencia intermedios.
Asegúrate de que routing_preference no esté configurado como TRAFFIC_AWARE_OPTIMAL.
Establece optimize_waypoint_order en true. Por ejemplo:
"optimizeWaypointOrder":"true",
Especifica el campo routes.optimizedIntermediateWaypointIndex en la máscara de campo:
Así es como la API de Routes optimiza el orden de las paradas intermedias en una ruta:
Indexa automáticamente los puntos de referencia según el orden en que los proporcionas en la solicitud, comenzando con el 0.
Optimiza el orden de los puntos de referencia con los números de índice que asignó a los puntos de referencia en la solicitud.
Devuelve el orden optimizado de los puntos de referencia en el objeto routes, en el campo waypoint_order, en routes.optimizedIntermediateWaypointIndex.
Ejemplo
Esta solicitud pide optimización para una ruta desde Adelaide, Australia Meridional, a cada una de las principales regiones vinícolas de Australia Meridional y, luego, el regreso a Adelaide.

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nBy default, the Routes API `Compute Routes`\nmethod calculates a route through multiple stops, called stopover waypoints, in\nthe order that you provide them.\n\nYou can have the Routes API optimize the provided route by rearranging\nstops in a more efficient order. Waypoint optimization optimizes for travel\ntime but also considers other factors such as distance and number of turns when\ndeciding which route is the most efficient.\n\nTo optimize waypoints\n---------------------\n\n1. Make sure none of the waypoints in the route have `via` set to `true`, for\n example: `{\"address\": \"Clare,SA\", \"via\": true}`. For more information about\n intermediate waypoints, see\n [Specify intermediate waypoints](/maps/documentation/routes/intermed_waypoints).\n\n2. Make sure the `routing_preference` is not set to `TRAFFIC_AWARE_OPTIMAL`.\n\n3. Set `optimize_waypoint_order` to `true`. For example:\n\n ```json\n \"optimizeWaypointOrder\": \"true\",\n ```\n4. Specify the `routes.optimizedIntermediateWaypointIndex` field in the field\n mask:\n\n **REST** \n\n ```json\n -H X-Goog-FieldMask: routes.optimizedIntermediateWaypointIndex\n ```\n\n **RPC** \n\n ```gdscript\n const (fieldMask = \"routes.optimizedIntermediateWaypointIndex\")\n ```\n\n### Understand how waypoint order is optimized\n\nHere's how the Routes API optimizes the order of waypoints in a route:\n\n1. Automatically indexes the waypoints based on the order you provide\n them in the request, starting with 0.\n\n2. Optimizes the order of the waypoints using the index numbers it\n assigned to the waypoints in the request.\n\n3. Returns the optimized waypoint order in the `routes` object, in the\n `waypoint_order` field, under `routes.optimizedIntermediateWaypointIndex`.\n\n### Example\n\nThis request asks for optimization for a route from Adelaide, South Australia,\nto each of South Australia's main wine regions, and then returning to Adelaide. \n\n```json\ncurl -X POST -H 'content-type: application/json' -d ' {\n \"origin\": {\n \"address\": \"Adelaide,SA\"\n },\n \"destination\": {\n \"address\": \"Adelaide,SA\"\n },\n \"intermediates\": [\n {\"address\": \"Barossa+Valley,SA\"},\n {\"address\": \"Clare,SA\"},\n {\"address\": \"Coonawarra,SA\"},\n {\"address\": \"McLaren+Vale,SA\"}\n ],\n \"travelMode\": \"DRIVE\",\n \"optimizeWaypointOrder\": \"true\"\n }' \\\n-H 'Content-Type: application/json' \\\n-H 'X-Goog-Api-Key: YOUR_API_KEY' \\\n-H 'X-Goog-FieldMask: routes,geocodingResults.intermediates.intermediateWaypointRequestIndex' \\\n'https://routes.googleapis.com/directions/v2:computeRoutes'\n```\n\nThe Routes API indexes the intermediate waypoints provided in the\nrequest, starting at 0. For example: \n\n```json\n0 {\"address\": \"Barossa+Valley,SA\"},\n1 {\"address\": \"Clare,SA\"},\n2 {\"address\": \"Coonawarrav,SA\"},\n3 {\"address\": \"McLaren+Vale,SA\"}\n```\n\nUsing the index numbers for the four waypoints provided in the request, the\nservice then returns the optimized order: \n\n```json\n\"optimizedIntermediateWaypointIndex\": [\n 3,\n 2,\n 0,\n 1\n ]\n```\n| **Caution:** Requests using waypoint optimization are billed at a higher rate on the SKU for Compute Routes Pro.
