The Matrix API returns travel times between many points.
For example, given three locations A, B, and C, the Matrix API will return a matrix of all travel times in seconds between the locations:
| A | B | C | |
|---|---|---|---|
| A | A → A | A → B | A → C |
| B | B → A | B → B | B → C |
| C | C → A | C → B | C → C |
The Matrix API will always return the duration or the distance on the fastest route for each element in the matrix, where an element is an origin-destination pair in the matrix. The Matrix API returns durations in seconds and distances in meters. It does not return route geometries.
Durations or distances between points may not be symmetric, since the routes may differ by direction due to one-way streets or turn restrictions. For example, A to B may have a different duration than B to A.
The Matrix API allows you to efficiently check the reachability of coordinates from each other, filter points by travel time, or run your own algorithms for solving optimization problems.
