Overview

API functionality

The Travel Time Matrix API calculates travel times and distances between multiple locations.

Built for high performance needs, a single request can process 100,000 locations in a few hundred milliseconds.

The API supports a range of transport modes including Driving, Public Transport, Walking, and Cycling.

Use cases

Typical use cases for a Travel Time Matrix include:

  • Adding travel times to a search application (e.g property portals, job boards, hotel booking sites) to improve relevancy of results and user experience
  • Route optimisation to increase scheduling efficiency
  • Last mile logistics to optimise deliveries
  • Ad serving to drive up CTRs
Choosing an Endpoint

The Travel Time Matrix API is accessible through 3 different endpoints. When choosing which endpoint is most suitable for your use case, the main criteria to consider are configurability of the request parameters vs scale and performance.

Usage limits

The following usage limits apply to the Travel Time Matrix API:

Concurrency

Maximum 250 matrices per minute

*A matrix is a single request which can include multiple origins and destinations.
Matrix Size

The maximum matrix size that can be included in a single request differs by endpoint:

Endpoint NameTravel Time MatrixTravel Time Matrix FastTravel Time Matrix Fast (Protobuf)
Matrix Size10 x 2,00010 x 100,0001 x 200,000
Travel Time

The maximum travel time support is different for each endpoint. Any origin-destination pairs outside of this limit will be returned as Unreachable.
