Can I pass multiple travel modes when using The Google Maps Distance Matrix API

Question

I need to calculating times and distances with multple travel modes, I try to pass multiple travel modes separated with | like this:

https://maps.googleapis.com/maps/api/distancematrix/json?origins=E149AQ&destinations=UB83PH|NW14SA|WC1E7HU|N78DB&mode=walking|bicycling|driving&language=en-GB&key=myKey

But it doesn't work as I expected.

Answer 1

Only a single travel mode is supported per request. To get results for multiple travel modes, make multiple requests.

The documentation implies that but doesn't state it explicitly:

Optional parameters

mode (defaults to driving) — 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.

Travel Modes

For the calculation of distances, you may specify the transportation mode to use. By default, distances are calculated for driving directions. The following travel modes are supported:

• driving (default) indicates distance calculation using the road network.

• walking requests distance calculation for walking via pedestrian paths & sidewalks (where available).

• bicycling requests distance calculation for bicycling via bicycle paths & preferred streets (where available).

• transit requests distance calculation via public transit routes (where available). This value may only be specified if the request includes an API key or a Google Maps API for Work client ID. If you set the mode to transit you can optionally specify either a departure_time or an arrival_time. If neither time is specified, the departure_time defaults to now (that is, the departure time defaults to the current time). You can also optionally include a transit_mode and/or a transit_routing_preference.

Note: Both walking and bicycling directions may sometimes not include clear pedestrian or bicycling paths, so these directions will return warnings in the returned result which you must display to the user.
