In Seattle we have and are currently expanding a system of "RapidRide" buses. These appear to have an average stop distance of around 0.3 miles (~500 meters) Wikipedia claims that RapidRide routes have on average 40% fewer stops than the 'regular' line that they replaced, which would mean the 'regular' buses have stops about every 300 meters. Anecdotally, I lived in London for a few years and now live in Seattle, and I would say these number's all roughly match my experience. Seattle's stops are spaced quite a bit further apart, but Seattle is also much less dense :) see https://www.theurbanist.org/2018/03/26/rainier-rapidride-metro-seeks-streamlined-route-7/ https://www.theurbanist.org/2018/03/26/rainier-rapidride-met... and https://en.wikipedia.org/wiki/RapidRide https://en.wikipedia.org/wiki/RapidRide
