What about similarly populated cities?
In new street additions, Zhuanghe built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Shucheng fluctuated in its street-construction patterns and Raigarh built increasingly disconnected streets over time. Looking at the full network, Shucheng and Raigarh both became progressively more disconnected, while Zhuanghe grew more disconnected from 1975 through 1991-2005, then improved. Zhuanghe and Shucheng have been converging in their street-network character since 1975.
