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