Are there rate limits for distance matrix service?
Note: Each query sent to the Distance Matrix service is limited by the number of allowed elements, where the number of origins times the number of destinations defines the number of elements. Note the following about rate limits on additional requests: The rate limit is applied per user session, regardless of how many users share the same project.

How does the distance matrix in Google Maps work?
The Distance Matrix API is a service that provides travel distance and time for a matrix of origins and destinations. The API returns information based on the recommended route between start and end points, as calculated by the Google Maps API, and consists of rows containing duration and distance values for each pair.

Certain parameters are required while others are optional. As is standard in URLs, all parameters are separated using the ampersand ( &) character. All reserved characters (for example the plus sign “+”) must be URL-encoded . The list of parameters and their possible values are enumerated below.
How to predict the value of a distance matrix?
While the training step–i.e., construcing the distance matrix–is straightforward, using it to predict the value of new data points is practically encumbered by the data retrieval–finding the closest 3 or 4 points from among several thousand or several million scattered in n-dimensional space.
How to use the distance matrix service in Google Maps?
