Again, how is a roundabout going to help this?

The morning’s traffic pattern clearly shows the real issue: Drakes Creek Road is at full capacity, with a steady line of cars. Meanwhile, Countryside Drive has no traffic, and Anderson Road has only a few cars trickling through. If the roundabout is designed primarily for these lesser-used streets, how can it fix the traffic congestion on Drakes Creek?

Wouldn’t this roundabout only make the situation worse, pushing more vehicles into the bottleneck without addressing the actual problem? Let's consider solutions that focus on the roads that really need them.
