Generally speaking, speed limits on Google Maps are used to warn the user that they have exceeded the speed limit and that it threatens safety. Does Google Maps inform the user about speed limits? The fact is that the speed limits are not always a guide for Google Maps, as many drivers exceed the maximum allowed speed, or reduce it for safety reasons, or because of the difficult situation on the road. Adjustment of the route happens all the time. Google Maps requires a GPS connection with satellites, and the app actively uses the user's location to understand at what speed he is moving and to correct the route. As a result, the app corrects the time of overcoming the distance and the time of reaching the finish line. This is usually due to the situation on the road: traffic jams, road accidents, repair work.

The current average speed of the vehicle.

Using the average speed, Google Maps displays an estimated time of arrival for the driver.Īdditional factors that affect the estimated arrival time: These readings have a fixed value and do not change that often. The main source for ETA calculation is the average speed. What data does Google Maps use to calculate ETA? The same ETA methodology is also used by other navigation apps. Google Maps uses this data to adjust your speed every few seconds. When you drive, the current position changes relative to satellites. Quick answer: To answer briefly, Google uses for its calculations not only the speed limit set on a particular stretch of road, but also the user's GPS.
