What about similarly populated cities?
In new street additions, Tacheng built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Suizhong fluctuated in its street-construction patterns and Jia fluctuated in its street-construction patterns. For the full network, Tacheng became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Suizhong became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Jia fluctuated in connectivity. Notably, Tacheng had a more sprawly network than Suizhong in 1975 but the two have since reversed their relative ranking.
