In new street additions, Lancaster built increasingly disconnected streets over time, while 巴虎屯村 built increasingly disconnected streets from 1975 through 1976-1990, then improved and Osijek built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns.
