The massive parking lots around malls and big box stores could be converted to condo's. Go stations could be communities.
Imagine commuters coming into Milton from the west in the morning, exiting from the ramp to a parking garage attached to the Go station. Half the system capacity could be on the other side of the 401, and on the return journey commuter drives right on to the ramp headed in the direction home. Of course a skybridge would be needed, but imagine the gasoline and time saved. A network of Go parking built around the 400 series highways could eliminate gridlock.
