Grid of the Gods
I like grid hellscapes that operate optimally. If you do as well, this is a great layout for it.
For just the Traffic Trident intersection, go here http://steamcommunity.com/sharedfiles/filedetails/?id=409590909
-6 lane one way trunk in the center
-Completely lightless with massive throughput
-Two lane vertical streets permit ease of access on side streets with no blind/weak spots for service.
-Central road perfect for plopping services down.
-For small optimization of traffic, you can put walking paths along the six lane segments, it makes a little difference, if you place 3 in a row, you almost certainly want to do this.
Have successfully testing plopping two of these cutouts in a row and have had 0 traffic issues with either commercial or industrial. 3 in a row causes some backup, but nothing extreme. 4 is too much.
IMPORTANT: IF YOU PUT A SECOND LINE PARRALEL TO THE CITY IN THE OPPOSING DIRECTION, DO NOT CONNECT THE TWO LINES EXCEPT VIA HIGHWAY, IT WILL JAM!
If you lay things out like this

Do NOT connect the left/right two lane one way roads like I did on first test of this. All traffic will jam itself at a single exit point.
