Guardian visualises London buses' slowdown
Reasonably balanced but inexplicably fails to consider the impact of ever-larger cars, which surely must be relevant especially when you see how declining bus speeds are so international. www.theguardian.com/uk-news/ng-i...
Looking at the map, the biggest slow downs are at the edges of London, supporting your larger car theory.
"And if you’re putting in more cycle lanes, it means it’s harder for bus passengers to travel. Dance resists this interpretation. “Mainly there are just too many cars. So moving people out of cars to more efficient spaces such as public transport, buses and bikes is part of that solution,” he says."
The international comparison is slightly complicated by the fact that it shows London bus speeds haven't actually decreased! Purely anecdotally from cycling round London I'd say the increase in smaller supermarkets with no loading yard must also be a big factor.
