Isochrones

Visualise where's reachable within a travel time catchment area.

Access URL: https://api.traveltimeapp.com/v4/time-map

Supports two HTTP request types:

  • GET - for simple requests using basic parameters only
  • POST - for more complex requests using advanced parameters
POST
GET

POST Request

A POST request should be used for any of the following use cases:

  • Using advanced parameters not available in the GET request
  • Creating multiple isochrones with one request
  • Calculating the Union or Intersection of multiple isochrones

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

Request Body

array[object]

Searches based on departure time. Leave departure location at no earlier than given time. You can define a maximum of 10 searches.

Hide child attributes

Used to identify each search in the results array. Must be unique among all searches.

Coordinates of the departure location.

Show child attributes

date in extended ISO-8601 format

Leave departure location at no earlier than given time. In ISO 8601 format. For example:
2024-12-05T07:00:00Z (representing UTC)
2024-12-05T07:00:00-05:00 (representing New York on Standard Time: UTC-05:00)

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

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

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.

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 and cycling+public_transport transportation modes.

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 and cycling+public_transport transportation modes.

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 transportation mode.

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.

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 and cycling+public_transport transportation modes.

Time in seconds required to board a ferry.
Default value is 0.
Cannot be higher than travel_time.
Used in ferry, driving+ferry, cycling+ferry and cycling+public_transport transportation modes. For public_transport mode, pt_change_delay is used instead.

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

Upper limit for the number of changes between public transit legs in a journey.
Used in public_transport, coach, bus, train, driving+train and cycling+public_transport transportation modes. For other modes the max_changes parameter is ignored.

Hide child attributes

Enable transit leg change limit?

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

object | optional

When enabled, range adds a departure window to the departure time, and a combined shape of all possible journeys departing within the window is returned.
Disabled by default.
Used in public_transport, coach, bus, train and driving+train transportation modes. For other modes range search parameters are ignored.

Show child attributes

Enable range search?

The width of the range window (in seconds).
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 included.
Maximum value is 43200 (12 hours).

array[string] | optional

Properties to be returned about the shapes.
Possible values: is_only_walking.
When selected, the is_only_walking parameter will return a value of True if a journey only involves walking (e.g for a public transport search in an area with no public transport available).

Specifies level of detail of returned shape.

Show child attributes
  • simple - level of detail is specified using a simple enumeration.
  • simple_numeric - level of detail is specified using integer numbers. This scale is an extension of simple scale.
  • coarse_grid - level of detail is specified as a number, used to simplify the generated shape to a set grid density.

Exact availability depends on the licence plan.

string | integer | optional

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.

Used with the coarse_grid scale type.
Specifies the side length (in metres) of the squares used to construct the shape. The larger the value, the less detailed the returned shape will be.
Minimum value is 600.

Specifies polygon filter of a single shape.

Show child attributes

At most this amount of largest polygons will be returned in a single shape. Must be greater than 0.

boolean | optional

Enable to remove holes from returned polygons.
Note that this will likely result in loss in accuracy.

  • approximate_time_filter (default) - the shape matches time-filter results as much as possible
  • road_buffering - the shape looks as if traversed roads of the search have been painted over with a wide brush
  • true (default) - returned shape will not cover large nearby water bodies
  • false - returned shape may cover nearby water bodies like large lakes, wide rivers and seas

object | optional

Adjusts the process of looking up the nearest roads from the departure / arrival points.

Show child attributes
  • 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).
  • 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).
