Access is a pretty vague word. I don’t think I could succinctly define it and I suspect no one else could either as it regards discussions about transit and transportation. Still, we can imagine a transit line that makes no stops at all and say that it would provide no access whatsoever. It would be useless. Similarly, a line with infinite stops where the bus moves infinitesimally after each stop before stopping again also has an access value of 0; it would also be useless.1
Somewhere in the middle is the Goldilocks stop spacing arrangement. Where does the m+ fall on this spectrum? Where do the other lines in the system? Might there be an ideal middle ground or are both either too crowded or sparse? Is there room for …lets call it ‘schedule diversity’ within a corridor? What effect does that have on effective frequency and average wait times at the skipped-over stops?
I’d like to hear SORTA’s and TANK’s official positions, or perhaps not positions but perspectives, on these questions as they move forward with their discussions of adding more rapid-transit-like lines to their systems. It’s not evident to me as an outsider that they’ve weighed the issue at all, at least publicly. Transit planners? Can you weigh in please? I’ve made my opinion clear in the above chart but I’m curious how SORTA and TANK would re-draw it and what they might add to it.
