We have rush hour trafic from 6 to 8 AM and 4 to 6 PM. Our rush hour is a lot lighter than most other areas of the USA.
The only consideration I give to relocation folk is look at where they are goiing to work. The St. Johns river runs through the city. If you work downtown, you are best to stay east of the river (between the ocean and the river). That way the bridge trafic does not get in the way, and that can be serious.
