Many of these topics will be discussed in the scenario planning portion of the Metropolitan Transportation Plan we’re working on right now, Horizon 2040. Until we get there though, you may want to look at how Walker diagrams each of these options, noticing that for each choices, one option seems to trigger a positive-feedback loop, while the other option does not.
And at the center of the “positive” choices? What Walker calls a single, consistent goal: the greatest possible number of jobs and other destinations located within 30 minutes one way travel time of the greatest possible number of residents.
To see how that would look locally, go to the Mapnificent website and play with the map a little. Then read the rest of Walker’s blog post and weigh in on his idea of “abundant access.”
