No idea. The traffic system is pretty fucking bi-polar in SC4. If you have the NAM, I suspect it has something to do with traffic from neighboring cities appearing and disappearing in numbers of over a thousand from border roads. If you don't… it could be any number of things.
Interesting fractal city layout, btw. I prefer extremely organic cities when I can get away with it (also helps to give those idiot Sims as few choices as possible to get where they need to go), but sometimes angular designs can be nice.
