What about similarly populated cities?
In new street additions, Salerno built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Gohana built increasingly disconnected streets from 1975 through 1976-1990, then improved and Acilia fluctuated in its street-construction patterns. For the full network, Salerno and Acilia both became progressively more disconnected, while Gohana grew more disconnected from 1975 through 1991-2005, then improved. Salerno and Acilia have been converging in their street-network character since 1975.
