In Atlanta we have light traffic on Friday mornings but heavy traffic on Friday evening. My theory is that morning traffic is almost entirely people going to work, of whom there are slightly fewer on Fridays, but evening traffic is both people coming home from work and people going out for fun. The extra fun trips on Friday evening more than make up for the people not working on Friday.
