array[object]
Searches based on departure time. Leave departure location at no earlier than given time. You can define a maximum of 10 searches.
string
You will have to reference this id in your searches. It will also be used in the response body. Must be unique among all locations.
object
The coordinates of the locations.
float
Latitude.
float
Longitude.
integer
Maximum journey time (in seconds). Maximum value is 14400 (4 hours) as standard. To discuss increasing this, please contact hello@traveltime.com.
date in extended ISO-8601 format
Leave departure location at no earlier than given time. In ISO 8601 format. For example:
2025-05-29T09:00:00Z (representing UTC)
2025-05-29T09:00:00-05:00 (representing New York on Standard Time: UTC-05:00)
Transportation mode and related parameters. The default parameters are sensible and it is usually enough to only specify the type.
cycling, driving, driving+train (only in Great Britain), driving+public_transport (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). Similarly, driving+public_transport search is for driving then taking any kind of public transportation.driving+public_transport is not supported on postcode endpoints. The maximum drive time can be configured using the driving_time_to_station parameter
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.
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).
integer | optional
Time in seconds needed to board public transportation vehicle.
Default is 0.
Cannot be higher than travel_time.
Used in public_transport, coach, bus, train, driving+train, driving+public_transport and cycling+public_transport transportation modes.
object | optional
Upper limit for the number of changes between public transit legs in a journey.
Used in public_transport, coach, bus, train, driving+train, driving+public_transport and cycling+public_transport transportation modes. For other modes the max_changes parameter is ignored.
Enable transit leg change limit?
Maximum number of changes between transit legs in a journey. Must be at least 0.
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.
Used in public_transport, coach, bus, train, driving+train, driving+public_transport and cycling+public_transport transportation modes.
integer | optional
Maximum time (in seconds) allowed for driving from the origin to the train station.
Default value is 1800.
Cannot be higher than travel_time.
Used only in driving+train and driving+public_transport transportation mode.
integer | optional
Maximum time (in seconds) allowed for cycling (including any ferry transfers) from the origin to the first stop/station.
Default value is 900.
Cannot be higher than travel_time.
Used only in cycling+public_transport transportation mode.
integer | optional
Time in seconds required to park a car or a bicycle.
Default value is 300.
Cannot be higher than travel_time.
Used in driving+train, driving+public_transport and cycling+public_transport transportation modes.
integer | optional
Time in seconds required to board a ferry.
Default value is 0.
Cannot be higher than travel_time.
Used in ferry, driving+ferry, driving+public_transport, cycling+ferry and cycling+public_transport transportation modes. For public_transport mode, pt_change_delay is used instead.
array[string]
Properties to be returned about the postcodes. Possible values: travel_time, distance
object | optional
When enabled, range adds a departure window to the departure time, and results are returned for any journeys that depart during this window.
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, driving+public_transport and cycling+public_transport transportation modes. For other modes range search parameters are ignored.
boolean
Enable range search?
integer
Maximum number of results to return. Limited to 5 results.
integer
The width of the range window (in seconds).
The window is applied 'backwards' from the arrival time. For example, with an arrival_time of 9am and a range width of 1 hour, all journeys arriving between 8am and 9am will be included. If no journeys are possible that arrive within the window, journeys that arrive earlier than the start of the window (before 8am in the example) are permitted.
Maximum value is 43200 (12 hours).
object | optional
Adjusts the process of looking up the nearest roads from the departure / arrival points.
string | optional
enabled(default) - walking time and distance from the departure location to the nearest road and from the nearest road to the arrival location are added to the total travel time and distance of a journey.disabled- these walking times and distances are not added to the total reported values (i.e the journey effectively starts and ends at the nearest points on the road network).
string | optional
both_drivable_and_walkable(default) - journey can only start or end on roads that are accessible by both: cars and pedestrians. This effectively means journeys can not start / end on motorways.any_drivable- journey can start or end on any road accessible by a car (including motorways).
