Hello. How can we help you?

The API endpoints and what they do

An overview of the different API endpoints available through TravelTime, covering isochrones, routes, journey time matrices, geocoding and more

The endpoints of the TravelTime API are split into 4 core tools, and then a range of ancillary tools.

Core Tools

Time Map

  • Create 'isochrones' showing the reachable catchment area in a given travel time (also known as trade areas)
  • Return individual isochrones, or unions of multiple isochrones, or intersections of multiple isochrones
  • Compatible with all methods of transport, including public transport
  • Use cases:
    • Real estate investment analysis
    • Retail store catchment areas
    • Public services accessibility 
    Retail-site-competition-analysis

Time Filter

  • Create origin-destination matrices of the journey times, distances, or public transport fares between 1000's of points in one go
  • Calculate a matrix of up to 10 x 2,000 in a single API call
  • Set a maximum travel time cut-off to automatically label points as reachable or unreachable
  • Compatible with all methods of transport, including public transport
  • Use cases:
    • Office relocation commute analysis
    • Customer market segmentation
    • SLA management

      Large-Matrix

Routes

  • Create A to B routes including turn-by-turn directions
  • Visualise the response on a map, or as a set of door-to-door instructions
  • Compatible with all methods of transport, including public transport
  • Use cases:
    • Transport network analysis
    • Employee commute visualisation
    • Infrastructure planning

Time Filter (Fast)

  • A stripped down, incredibly fast version of the standard Time Filter endpoint 
  • Calculate a matrix of up to 10 x 100,000 in a single API call
  • Compatible with driving and public transport modes
  • Use cases:
    • Consumer-facing sites where large volumes of data need to be searched / sorted / filtered by travel time with optimum performance - for example, here
    • Creation of large origin-destination matrices such as between all postcodes or LSOAs

Time Filter (Fast) is only currently supported in the UK & Ireland

Ancillary Tools

Time Filter Postcodes / Sectors / Districts

  • Find reachable postcodes, postcode sectors, and postcode districts based on travel time from an origin or destination
  • Compatible with driving and public transport modes
  • Use cases:
    • Targeted marketing mailshots
    • Logistics planning
    • Public services provisioning 

Geocoding

  • Convert addresses (e.g postcodes) into lat-long coordinates
  • These coordinates can then be used to display the addresses on a map, or as inputs for one of the other TravelTime API endpoints
  • Limit results to a single country if required

 

Reverse Geocoding

  • Convert lat-long coordinates into readable addresses (i.e street addresses)
  • Return multiple matches or simply the best match for each

 

Map Tiles

  • Add base maps to a project using raster tiles 

map_tile

 

Map Info

  • Receive information about currently supported countries
  • Includes the dates for the available window of public transport data for each country 

Supported Locations

  • Based on lat-long coordinates, find out whether a location is currently supported
  • For locations that are supported, the id of the map which contains that location is also returned
