Generally, those traveling less than 30 minutes are probably commuting within the county, while those traveling 30+ minutes are most likely out-of-county commuters. Driving 10-19 minutes is the most typical commute time. Recently, however, percent of 10-19 minute commutes has sharply declined, while the percentage traveling for 60+ minutes has risen from 15% in 2012 to 20.3% in 2016. Time increases could indicate heavier traffic congestion and increased total vehicle miles traveled within San Joaquin county.
