London congestion pricing, then and now
It’s already Sunday and I’ve exhausted my cache of unread blog posts from the week, so I went in search of new blogs to read and can across this really good one: Spatial Analysis. A post from December has this set of maps – private turnpikes in 18th century London and the congestion zone map in the 21st:
It looks to me like the old map is skewed and that they are actually quite similar, but I’m having trouble aligning them – maybe someone who knows London better than me could compare them for us?
Again, that’s from spatialanalysis.co.uk.
They’re fairly well aligned. The apparent differences are accounted for by a) the expense then and now of creating a map that exactly corresponds to survey data; and b) that the maps cover different areas. The old map extends further east, north, and south, although the western extent of both is about the same.
