This caught my eye when I was citing some unrelated stats about travel distances in the NTS (PDF). I must have seen it before, but perhaps just skipped over it and didn't notice what it was saying. Or perhaps others have already commented on it and I've forgotten this one amongst all the other noise about cycling revolutions. It looks even worse than this. The volatility, of course, gives plenty of opportunity to claim year-on-year booms. Still, could be worse. Could be a walking revolution.
The next graph in the document — showing the massive increase in rail travel over the same period — is far more familiar…
