The same issue and basically the same spatial pattern shows up on walk accessibility.
Interestingly, there is a frequency-based transit line along Blue Hill Avenue, which is the center of that image.
Ah, and frequency-based lines are boarded using a monte carlo simulation, so random variation between runs is not unexpected - the variation is small here (we're talking about changes of access to a few hundred jobs out of the entire Boston job market). Retrying without frequency-based lines, which should be deterministic.
Without the frequency service, increasing the walk distance causes three decreases in accessibility in Boston. Of course it shouldn't cause any, but that's a lot better than it was.
For bike distance, it's perfectly clean.
That probably shouldn't happen.
