What about similarly populated cities?
In new street additions, Hongjiang built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Khargone built increasingly disconnected streets over time and Bayda built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Khargone and Bayda both became progressively more disconnected, while Hongjiang grew more disconnected from 1975 through 1976-1990, then improved. Hongjiang and Khargone have been growing further apart in their street-network character since 1975.
