I understand mapping the shortest routes, tollways vs non tollways, ect but how is programming like google maps able to determine the amount of time your commute will take due to traffic patterns and congestion?

The simplest way is to just take the distance divided by the speed limit on each segment to get a best case, then multiply it by a factor of 0.5-0.9 based on how much of the rout features things like traffic lights and stop signs.
That won’t take into account congestion and traffic, but it gives you a baseline.
Things like google maps are connected to the internet, where they have a database on current traffic built by other Android phones with location services/Google maps running and just normal traffic condition reporting data.
