In new street additions, Pingyi fluctuated in its street-construction patterns, while Swindon built increasingly disconnected streets from 1975 through 1976-1990, then improved and Tongliang built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Pingyi became progressively more disconnected, while Swindon grew more disconnected from 1975 through 1991-2005, then improved and Tongliang became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Pingyi and Swindon have been converging in their street-network character since 1975.
