JSON API /v4/time-filterCreate a distance matrix with the travel times and distances between thousands of locations in one go.
Supports two HTTP request types:
- GET - for simple requests using basic parameters only
- POST - for more complex requests using advanced parameters
With both request types, to create a many-to-many matrix you will need to use multiple searches.
For example given three points A, B, C you would need three arrival searches - one for each point.
- A -> { B, C }
- B -> { A, C }
- C -> { A, B }
Access URL: https://api.traveltimeapp.com/v4/time-filter
A POST request should be used for any of the following use cases:
- Using advanced parameters not available in the GET request
- Calculating a many-to-many matrix
The access URL is the same as the GET request format, but the differences are:
- Authentication is included in the request Headers
- Parameters are included in the request Body

2025-07-11T10:00:00-05:00 (representing New York on Standard Time: UTC-05:00)
integer
Maximum journey time (in seconds). Maximum value is 14400 (4 hours) as standard. To discuss increasing this, please contact hello@traveltime.com.
array[string]
Properties to be returned for each arrival location. Possible values:
travel_time,
route,
distance (driving, walking and cycling modes only),
distance_breakdown (driving, walking and cycling modes only),
fares (UK only. public_transport, coach, bus, train, driving+train and driving+public_transport modes only)

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.
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
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.
integer | optional
Maximum time (in seconds) allowed for driving from the origin to the train station.
Default value is 1800.

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.
string | optional
Specifies how traffic conditions are accounted for in driving modes. The full impact depends on the typical traffic conditions for the specific area and time of day - when congestion is higher (e.g in more urban areas, and at busier times of the day) the parameter will have a bigger impact.
balanced (default) - uses typical traffic conditions for the chosen time of day.
optimistic - uses lighter traffic conditions for the chosen time of day, resulting in shorter travel times.
pessimistic - uses heavier traffic conditions for the chosen time of day, resulting in longer travel times.
Used in driving, driving+ferry, driving+train, and driving+public_transport transportation modes.
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.

The window is applied 'forwards' from the departure time. For example, with a departure_time of 9am and a range width of 1 hour, all journeys departing between 9am and 10am will be considered. If no journeys are possible that depart within the window, journeys that depart later than the end of the window (after 10am in the example) are permitted.
