Very interesting, but I’m not sure I agree with him fully. We’re talking about cities here, and they tend to be big. Sure, encouraging people to walk a Mile is nice, but anything longer and people will look for some kind of transportation, no matter how walkable the city is.
I mean used to walk home from the trainstation after work, just to get some exercise and fresh air, but not everybody has time for this.
the solution is subways.
Sure, and I love subways. They tend to be very expensive though and digging the tunnels might harm the stability of earth and buildings above them.
But good point.
1 mile is definitely too far for sure. This researcher recommends 400m as the default between metro stops. https://humantransit.org/2011/04/basics-walking-distance-to-transit.html
You can combine a traditional city with a train system, to get the best of both worlds. It’s not either/or.
