Nice visualization! I made something similar a while back (refresh the page if it doesn't start properly): http://sinelaw.github.io/jammed/src/

It includes drivers with different personalities (buses accelerate slower, some drivers are daydreaming, etc.) and lane changing (people change lanes when it's beneficial)

Very nice, but since there is no transition the lane changing looks a bit too jerky so that at first I thought it was broken.

Right - that needs to be fixed. Besides the graphical issue, the lane changing is instantaneous, which is not realistic.
