Try this link for NYT on Mediaeval mapping at various sites, it basically just gives a background for the Cambridge map and mentions some other sites. If not, I can download a copy. Mostly it was the Cambridge map site that was important. It has other cities than London. There is also some site that gives main road routes in Continental Europe from about 1000 to 1500,,, but I couldn't get the site to do much.
