I Really Like Wheel Style Cities But They Are Not Efficient For Pedestrian Traffic

The city I've been working on today is shaping up nicely, but I'm very quickly going to start having issues with traffic. I've managed to mitigate a lot with public transportation, but even so my intersections are BARELY handling the traffic I have. Once I fill out the rest of my skyscrapers and start adding in the further out apartments, I feel traffic becoming NIGHTMARISH.
