I keep saying that vehicles need to be on a different layer than pedestrians and cyclists. I think what I'd prefer to see is a reduction in the total number of streets, but for each street that remains to be fully dedicated to vehicle traffic, with wide single direction entry/exit ports for buildings. Pedestrians would walk through and between buildings at non-vehicle level height (under them seems to be the best option); most likely beneath the roads that were removed (imagine skylights where the roadway was). Obviously the pedestrian areas would be insulated from the weather.
