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.
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.
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.
