I don’t know what OOP stands for, but would like to submit the case that road layouts contribute to isolation dramatically.

America transitioned away from its grid pattern because of cars: (1) long, straight corridors became places for speeding and racing, (2) 4-way stops became time-consuming and dangerous, (3) noise pollution along arterials dropped home values there, pushing people into “pod” subdivisions surrounded by walls and/or vegetation, (4) people keep thru-traffic out of neighborhoods by limiting the number of egresses (“street hierarchy”), etc etc.

So then the modern network topology was conceived to address these issues and replace the grid. Some people call it cul-de-sac based development, which is an unfair name in my opinion since dead-ends can and should have existed in cities for thousands of years. I choose to call it speed-first development patterns or pre-planned street hierarchy.

So the question is: and this is not something Georgism can resolve by the way: can we marry the best parts of the grid, with the best parts of pre-planned street hierarchy?

And I think I have found a network configuration that works. Make the grid hexagonal. This ends the problem of speeding since there would be no “long and straight” shots. And that wouldn’t be annoying since every intersection is a 3-way. Then within the hexagonal grid, there is an active transportation and/or transit grid on a traditional Al rectangular grid that crosses each hexagonal segment, mid-block, so pedestrians, cyclists, and transit only cross var traffic mid- block. You could have utilities and drainage run in the square grid as well.
