Google has shed some light on the process that allows them to accurately detect the movement of traffic
. When a person uses Google Maps to navigate they are shown whether the traffic along their route is heavy or light, an estimated travel time, and the estimated time of arrival (ETA).
How does Google know about traffic?
Here’s how it works:
All iPhones that have Google Maps open and Android phones that have location services turned on send anonymous bits of data back to Google
. This allows the company to analyze the total number of cars, and how fast they’re going, on a road at any given time.
How accurate is the speed on Google Maps?
Google maps will usually show a more accurate value however even that is not 100% your true speed
. The reason for this is that there is a small delay between the signal traveling from your phone to Google’s satellites and back. While traveling at high speeds even a small delay can result in a 1-2% error.
Does Google Maps predict future traffic?
To predict what traffic will look like in the near future,
Google Maps analyzes historical traffic patterns for roads over time
. The software then combines this database of historical traffic patterns with live traffic conditions, using machine learning to generate predictions based on both sets of data.
How does Apple Maps know traffic?
Routing and Traffic: While you are in transit (for example, walking or driving),

How does Google Maps determine travel time?
The service estimates travel time
by looking at the distance between your current location and the destination
