First impression: Ahhh! I can feel the very chaotic nature of that area from here! So much signage, cars, everything... :-)
Artistic: A very nice capture of a very busy scene. With so many signs etc competing for the eye all the time, I can't help but wonder why there isn't a huge pileup at every corner. But as you said in your title, it's peaceful chaos. The b/w works well and helps to capture the shapes and forms. In colour it would probably be too overwhelming.
Technical: Looks very crisp and not noisy at all, as can be Nikon's bugaboo. You did a good job of exposing for the scene, esp with a high ISO, and the light is just enough to illuminate the scene in all its madness without too much glare or punchy dark areas. Composition is a little drab, shot from lower down or higher up may have given you a more interesting angle. (Just don't get killed, is all)
Overall: A good shot of what is clearly par for the course for you in terms of your daily travel. Keep up the good work and keep shooting!
