Questions tagged [google-roads-api]

The Google Roads API identifies the roads a vehicle was traveling along and provides additional metadata about those roads, such as speed limits.

The Google Roads API allows you to map GPS coordinates to the geometry of the road, and to determine the speed limit along those road segments. The API is available via a simple HTTPS interface, and exposes the following services:

  • Snap to roads This service returns the best-fit road geometry for a given set of GPS coordinates.
  • Nearest roads This service returns individual road segments for a given set of GPS coordinates.
  • Speed limits This service returns the posted speed limit for a road segment.

The Roads API is also available with the Java Client, Python Client, Go Client and Node.js Client for Google Maps Services.
