Google Maps will soon show you real-time status updates on public transit — like trains or buses in your city — so you know exactly where they are, and if your bus or train is running a bit early or late. Google said it will be available in 80 regions around the world initially but will continue to roll out to more areas.

Google on Monday announced a few big changes coming to Google Maps on iPhone and Android that might help you save time during your commute.

The app also has a new "commuter" tab that will show you all the information you need about your commute. If Google knows that you tend to drive part of the trip and then ride a train for another part, it will show you information about the traffic and train schedules. If it knows your commute will take longer than normal, it will send alerts about alternate routes before you leave the office or house.

Google Maps will also let you control your music from Spotify, Apple Music and Google Play Music from within the app, so you don't have to switch back and forth to quickly change a song while driving.

Google said the update will roll out to Google Maps users on iPhone and Android this week.
