departure_searches.travel_distance

integer

Maximum journey distance (in meters).
Maximum value is 800000 (800km) as standard. Minimum value is 75 meters. Although travel distance is limited, computations are still performed by considering fastest journeys (minimizing travel time). To discuss increasing this, please contact hello@traveltime.com.

Transportation mode and related parameters. type is a mandatory field, but all other fields are optional and default values are used if not specified.

Show child attributes

departure_searches.transportation.type

string

driving, walking, cycling, driving+ferry,, cycling+ferry, ferry.

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.boarding_time

integer | optional

Time in seconds required to board a ferry.
Default value is 0.
Cannot be higher than 1h.
Used in driving, walking, cycling, driving+ferry, cycling+ferry and ferry transportation modes.

object | optional

Specifies level of detail of returned shape.

Show child attributes

departure_searches.level_of_detail.scale_type

string

simple - level of detail is specified using a simple enumeration.

Can either be a string or an integer depending on scale_type used.

Available options when using string: lowest, low, medium, high, highest. Used with simple scale type. Returned shape will be the least detailed with the lowest setting, and the most detailed with the highest setting.
Available options when using integer are between -20 and 2. Used with simple_numeric scale type. The lower the number, the less detailed the returned shape will be. Values from -2 to 2 are equivalent to the lowest to highest values of the simple scale type.
