I built a city in Sim City 3 exactly like this and it was pretty stellar. The entire city was split into 8 wedges, between each wedge was a continuous span of parks, trails, and water features, which all ran to a grand central park. Light rail and subway connected radially and tangentially. Roads were small and limited mostly to connecting blocks (a quasi-necessary feature due to the way SimCity simulates traffic, though later I learned I could construct without any roads).
How did Sims react to this hyper-planned city? Massively booming commerce, health, longevity and education through the roof. The only downside was the insane upfront cost to build in such a structured way (though interestingly, a huge chunk of that cost was subway. If I were in Sim City 4, there are more raised rail options).
I actually tried an annular highway (beltway) around the whole city (as is found in many real-world cities), and much to my chagrin, it was a headache that largely made traffic worse, just like real-world beltways.
