The API endpoints and what they do

The API endpoints and what they do

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

Core tools:
 

Ancillary tools:
 

 

Core Toolsanchor icon

Time Mapanchor icon

  • 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 

What the API endpoints do.png

Time Filteranchor icon

  • 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

Routesanchor icon

  • 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)anchor icon

  • 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 Toolsanchor icon

Time Filter Postcodes / Sectors / Districtsanchor icon

  • 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 

 

Geocodinganchor icon

  • 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 Geocodinganchor icon

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

 

Map Tilesanchor icon

  • Add base maps to a project using raster tiles 

map_tile

 

Map Infoanchor icon

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

 

Supported Locationsanchor icon

  • 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
