What about similarly populated cities?
In new street additions, Qikou built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Pianguan fluctuated in its street-construction patterns and Minusinsk built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Qikou became progressively more connected, while Pianguan fluctuated in connectivity and Minusinsk became progressively more disconnected. Qikou and Pianguan have been converging in their street-network character since 1975.
