date in extended ISO-8601 format

Leave departure location at no earlier than given time. In ISO 8601 format. For example:
2024-11-20T09:00:00Z (representing UTC)
2024-11-20T09:00:00-05:00 (representing New York on Standard Time: UTC-05:00)

departure_searches.travel_time

integer

Maximum journey time (in seconds).
Maximum value is 14400 (4 hours) as standard. To discuss increasing this, please contact sales@traveltime.com.

departure_searches.transportation

string

Transportation mode and related parameters. The default parameters are sensible and it is usually enough to only specify the type.

Show child attributes

departure_searches.transportation.type

string

cycling, driving, driving+train (only in Great Britain), public_transport, walking, coach, bus, train, ferry, driving+ferry, cycling+ferry or cycling+public_transport (only in Netherlands).

Note - a driving+train search is for driving then train (i.e driving to a station and continuing by train). The maximum drive time can be configured using the driving_time_to_station parameter

departure_searches.transportation.include_roads

array[string] | optional

Additional road types to included when executing search. Only affects driving and driving+ferry transportation modes. Possible values:

track - unpaved roads that only allow very slow driving speed or even require an off-road capable vehicle.
restricted - roads that are not publicly accessible and may require a special permit. By default all of these roads are excluded from the search.

departure_searches.transportation.walking_time

integer | optional

Maximum time (in seconds) allowed for walking at the start and end of a public transport journey. i.e:

the maximum walking time from the origin to the first stop/station, and
the maximum walking time from the final stop/station to the destination

These limits are independent and not cumulative. They only apply to the first and last walking legs of the journey - all walking times between public transport legs are limited to 600s (10 minutes) each.

The default value is 900.

Cannot be higher than travel_time.

boolean | optional

If set to true, the crossing of country borders is disabled. Only available with the driving transportation mode, and is enabled by default (false).

departure_searches.transportation.max_changes

departure_searches.transportation.max_changes.limit

integer

Maximum number of changes between transit legs in a journey. Must be at least 0.

departure_searches.reachable_postcodes_threshold

float

A number between 0.0 and 1.0. For example, if 0.5 is used, only sectors that have at least 50% postcodes that can be reached within the given travel_time will be included in the response. 0 will return sectors that have at least a single reachable postcode

departure_searches.properties

array[string]

Properties returned about the sectors.

travel_time_reachable - travel time statistics calculated from reachable postcodes in the sector
travel_time_all - travel time statistics calculated from all postcodes in the sector

In the results array, the properties of these multiple alternative results are sorted by travel_time in ascending order.
Disabled by default.
Used in public_transport, coach, bus, train, driving+train and cycling+public_transport transportation modes. For other modes range search parameters are ignored.
