In new street additions, Panjin built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Muscat built increasingly disconnected streets from 1975 through 1991-2005, then improved and Bakersfield built increasingly disconnected streets over time. Looking at the full network, Muscat and Bakersfield both became progressively more disconnected, while Panjin became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Panjin had a more sprawly network than Bakersfield in 1975 but the two have since reversed their relative ranking.
