The traffic sensors are usually installed by government agencies to check the volume and speed of traffic in real-time. The sheer number of drawbacks to predicting traffic from the sensors makes it a far less reliable option than using anonymized location data from users. This method is pretty dated and is increasingly less popular over the years. This method makes up most of Google’s knowledge of real-time traffic information. ![]() If many drivers using Google Maps converge at a specific area, Google deduces that it’s a traffic hold up, and that’s how they provide meaningful traffic data by crowdsourcing. Since you agree to this, Google is free to use your anonymized location data to provide real-time traffic information to drivers using Google Maps, and the traffic information you see is also a collection of traffic information from other drivers. By using Google Maps, you automatically agree to share your location services for diagnostic services and to improve the app. It’s common knowledge that you must turn on the location services on your smartphone to use Google Maps effectively how else is it going to know your location otherwise?īut Google Maps uses your location for things far more complicated than telling your real-time location.
