What about similarly populated cities?
In new street additions, Yangcheng built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Sinpho built increasingly disconnected streets from 1975 through 1991-2005, then improved and Dajindian built increasingly disconnected streets over time. For the full network, Yangcheng became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Sinpho grew more disconnected from 1975 through 1991-2005, then improved and Dajindian became progressively more disconnected. Yangcheng and Sinpho have been growing further apart in their street-network character since 1975.
