In new street additions, Ramnagar built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Leuven fluctuated in its street-construction patterns and Xingtang built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Leuven and Xingtang both became progressively more disconnected, while Ramnagar became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards.
