Why do buses bunch?
I commute in LA and observe (and am impacted) by this regularly; so much so, that I've been meaning to write the municipal operator about solving the issue, or at least reduce the tendency (attractor?).My mitigation idea: When the buses become bunched; the forward bus should switch to 'Disembark Only' mode. (Most modern buses I've seen have a preset to post this on the LED signage). This way it can pass all the stops with folks waiting and (we hope) will make enough time up to get far enough down the line to remain un-bunched.Then, by some condition (e.g.,"back to within 5 minutes of posted schedule") switch back to normal "pickup & drop-off" mode.It's very cool to see someone else noticing and thinking about this phenomena.To quote the great thinker Yogi Berra, "You can observe a lot just by watching."
