What about similarly populated cities?
In new street additions, Rijeka built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Poncowati built increasingly disconnected streets over time and Ambah fluctuated in its street-construction patterns. For the full network, Rijeka and Poncowati both became progressively more disconnected, while Ambah fluctuated in connectivity. Notably, Rijeka had a more sprawly network than Ambah in 1975 but the two have since reversed their relative ranking.
