What about similarly populated cities?
In new street additions, Quanpu and Suichuan both built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Twante fluctuated in its street-construction patterns. For the full network, Quanpu and Suichuan both grew more disconnected from 1975 through 1976-1990, then improved, while Twante became progressively more disconnected. Notably, Quanpu had a more sprawly network than Twante in 1975 but the two have since reversed their relative ranking.
