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?

Aggregate data collected over a period of time. Google maps receives position and time info from your (and everybody else’s) phone. Using all that data, Google can predict how long it will take you to reach your destination. Because the data is updated so frequently, it can see traffic jams or other hold ups and update it’s prediction accordingly.
