@Jnjoe Don't really know, but in that article there was a quote:
Early versions of Google Maps provided information to users about how long it would take to travel a particular road in heavy traffic conditions. Traffic information was based on historical traffic data and was not particularly accurate.[3]
In 2004 Google acquired ZipDash, a company specializing on realtime traffic analysis.[4] In 2007, Google integrated ZipDash's technology into Google Maps, offering traffic data based on information gathered anonymously from cellular phone users.[5][6]
There is more to that. Why am curious is. I navigated in a type of rural not too developed city, but the traffic was not showing and there was serious traffic. When I got to the city it work when there was traffic. Can you explain both?
That the most accurate way to do that , and it's 💯% accurate , those days nobody drive car without smart phone or let's say 90% have samrt phone and the new regulations for mobiles industry to have GPS
Yes I can and I will. Do you know the different types of GPS. If yes then you must know about coverage area and strength of those systems. In rural area (i.e. mean hilly regions) all devices which have GPS systems other than gnss can function properly. And many people don't have privileges to own such a device in "rural area". So there is no data for Google to process. And moreover even their devices are capable enough, they don't have access to economical Internet for the information to be updated real time.
And finally occasional traffic congestion might not be show in the Google maps.
