What about similarly populated cities?
In new street additions, Xinyi fluctuated in its street-construction patterns, while Anji fluctuated in its street-construction patterns and Shimla built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Xinyi fluctuated in connectivity, while Anji became progressively more disconnected and Shimla became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Xinyi and Anji have been converging in their street-network character since 1975.
