In the SF Bay Area, commuting by car over the past 15 years, I've found that there are no generalizations I can safely make about traffic during a particular time of day, which applies to all routes and all directions. I became an early riser for a particular job and have stayed on that sleep schedule for (arguably indirectly related) health reasons, so I'm awake by 13:00 UTC every day, which is 6am or 5am, depending on Daylight Silly Time. However, I tend to adjust my commute departure time such that I get a good overlap of being in the office with my cow-orkers.
