I'm not sure if those would lead to really major changes to congestion, specially once you consider that there will be increased demand for driving once self-driving cars are ubiquitous. The only approach to truly reducing congestion is to switch towards denser public transit. BTW, I suspect that the bigger impact of self-driving cars would actually be the reduced need for parking space.
