Google Maps just added a benefit for commuters who use public transportation. Google announced that the latest update includes predictions on how crowded your bus or train might be. 

Starting in October, the company asked Google Maps users who traveled between 6 a.m. and 10 a.m. to give details on their commute, like the number of seats available. Google used this user reported data to create it's latest prediction technique, according to TechCrunch.

The update also includes real-time updates for bus delays based on traffic conditions. This is expanding on a feature already available in some cities. 

Think your commute is especially bad? Google compiled a list of the most crowded transit lines in the world — New York's L Train was the only U.S. line to crack the top 10, ranked last. Buenos Aires's Urquiza Line tops the list as the most crowded transit line. 

Me during my commute: MOVE. THAT. BUS.

Now you can see real-time delays and how crowded your bus is on your way to work
