Interface DistanceMatrixRequest

Type declaration

• Optionalarrival_time?: number | Date

  Specifies the desired time of arrival for transit requests, in seconds since midnight, January 1, 1970 UTC. You can specify either departure_time or arrival_time, but not both. Note that arrival_time must be specified as an integer.

• Optionalavoid?: TravelRestriction[]

  Introduces restrictions to the route. Valid values are specified in the Restrictions section of this document. Only one restriction can be specified.

• Optionaldeparture_time?: number | Date

  The desired time of departure. You can specify the time as an integer in seconds since midnight, January 1, 1970 UTC. Alternatively, you can specify a value of now, which sets the departure time to the current time (correct to the nearest second).

  The departure time may be specified in two cases:

  • For requests where the travel mode is transit: You can optionally specify one of departure_time or arrival_time. If neither time is specified, the departure_time defaults to now (that is, the departure time defaults to the current time).

  • For requests where the travel mode is driving: You can specify the departure_time to receive a route and trip duration (response field: duration_in_traffic) that take traffic conditions into account. This option is only available if the request contains a valid API key, or a valid Google Maps APIs Premium Plan client ID and signature. The departure_time must be set to the current time or some time in the future. It cannot be in the past.

    Note: Distance Matrix requests specifying departure_time when mode=driving are limited to a maximum of 100 elements per request. The number of origins times the number of destinations defines the number of elements.

• destinations: LatLng[]

  One or more locations to use as the finishing point for calculating travel distance and time. The options for the destinations parameter are the same as for the origins parameter, described above.

• Optionallanguage?: string

  The language in which to return results.

  • If language is not supplied, the API attempts to use the preferred language as specified in the Accept-Language header, or the native language of the domain from which the request is sent.
  • The API does its best to provide a street address that is readable for both the user and locals. To achieve that goal, it returns street addresses in the local language, transliterated to a script readable by the user if necessary, observing the preferred language. All other addresses are returned in the preferred language. Address components are all returned in the same language, which is chosen from the first component.
  • If a name is not available in the preferred language, the API uses the closest match.
  • The preferred language has a small influence on the set of results that the API chooses to return, and the order in which they are returned. The geocoder interprets abbreviations differently depending on language, such as the abbreviations for street types, or synonyms that may be valid in one language but not in another. For example, utca and tér are synonyms for street in Hungarian.

• Optionalmode?: TravelMode

  Specifies the mode of transport to use when calculating distance. Valid values and other request details are specified in the Travel Modes section of this document.

  Default

  TravelMode.driving
  Copy

• origins: LatLng[]

  The starting point for calculating travel distance and time. You can supply one or more locations separated by the pipe character (|), in the form of an address, latitude/longitude coordinates, or a place ID:

  • If you pass an address, the service geocodes the string and converts it to a latitude/longitude coordinate to calculate distance. This coordinate may be different from that returned by the Geocoding API, for example a building entrance rather than its center.

    origins=Bobcaygeon+ON|24+Sussex+Drive+Ottawa+ON

  • If you pass latitude/longitude coordinates, they are used unchanged to calculate distance. Ensure that no space exists between the latitude and longitude values.

    origins=41.43206,-81.38992|-33.86748,151.20699

  • If you supply a place ID, you must prefix it with place_id:. You can only specify a place ID if the request includes an API key or a Google Maps APIs Premium Plan client ID. You can retrieve place IDs from the Geocoding API and the Places SDK (including Place Autocomplete).

    origins=place_id:ChIJ3S-JXmauEmsRUcIaWtf4MzE

  • Alternatively, you can supply an encoded set of coordinates using the Encoded Polyline Algorithm. This is particularly useful if you have a large number of origin points, because the URL is significantly shorter when using an encoded polyline.

    • Encoded polylines must be prefixed with enc: and followed by a colon (:). For example: origins=enc:gfo}EtohhU:
    • You can also include multiple encoded polylines, separated by the pipe character (|). For example: origins=enc:wc~oAwquwMdlTxiKtqLyiK:|enc:c~vnAamswMvlTor@tjGi}L:|enc:udymA{~bxM:

• Optionalregion?: string

  The region code, specified as a ccTLD (country code top-level domain) two-character value. Most ccTLD codes are identical to ISO 3166-1 codes, with some exceptions. This parameter will only influence, not fully restrict, results from the geocoder. If more relevant results exist outside of the specified region, they may be included.

• Optionaltraffic_model?: TrafficModel

  Specifies the assumptions to use when calculating time in traffic. This setting affects the value returned in the duration_in_traffic field in the response, which contains the predicted time in traffic based on historical averages. The traffic_model parameter may only be specified for requests where the travel mode is driving, and where the request includes a departure_time, and only if the request includes an API key or a Google Maps APIs Premium Plan client ID.

  Default

  TrafficModel.best_guess
  Copy

• Optionaltransit_mode?: TransitMode[]

  Specifies one or more preferred modes of transit. This parameter may only be specified for requests where the mode is transit.

• Optionaltransit_routing_preference?: TransitRoutingPreference

  Specifies preferences for transit requests. Using this parameter, you can bias the options returned, rather than accepting the default best route chosen by the API. This parameter may only be specified for requests where the mode is transit.

• Optionalunits?: UnitSystem

  Specifies the unit system to use when expressing distance as text.
