What about similarly populated cities?
In new street additions, Delduar built increasingly disconnected streets over time, while 천리마구역 built increasingly disconnected streets from 1975 through 1976-1990, then improved and Sirjan built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns.
