What about similarly populated cities?
In new street additions, Taixing and Kirov both built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Saki built increasingly disconnected streets over time. Looking at the full network, Kirov and Saki both became progressively more disconnected, while Taixing grew more disconnected from 1975 through 1991-2005, then improved. Notably, Taixing had a more sprawly network than Saki in 1975 but the two have since reversed their relative ranking.
