Dear all,
As I am conducting a research on road network/density at the global level. I found it is very hard to locate data of this kind. I find some second-hand data from 1960-1980, which is a bit outdated. Therefore, I was wondering where I can find this kind of data?
For samples, capital cities like London, Paris, Bucharest, Prague, West/East Berlin, Munich and etc. are highly appreciated.
Thank you very much.
Best,
Chris
