I’ve decided to give this interval thing a try. Main problem is reconciling it with the requirement that all route variants have a relation to themselves. My route has two ‘core’ variants, one of which is a short run of the other. The ‘1’ variant runs at 2 BPH, and the ‘2’ variant also runs at 2 BPH. This is obviously a total of 4 BPH for anyone wanting to travel both to and from points on the common section of route. However, they are engineered so that they interleave, and that the 4 BPH really is ‘one every fifteen minutes’, as opposed to four buses spread irregularly about within the hour.

This is one reason I’d like to have route segments; we could specify the interval for alternative routes, short-runnings, and telescopings without having to use heuristics to infer it by spotting common parts of routes.

This particular pair of examples (relations 8,257,900 and 8,265,640) are midday-only buses (‘midday’ within the definition of the interval tag). Can someone check I’ve done it right, please. The defining characteristic of this route/variant is that it serves a village, which is effectively inaccessible due to traffic congestion other than between 0900 and 1500. There is one other such trip, in the afternoon peak, but I’ve omitted that, as I’d rather understate the availability of buses on that route.
