What about similarly populated cities?
In new street additions, Guemar built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Ghammas built increasingly disconnected streets over time and Jesse built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Guemar became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Ghammas became progressively more disconnected and Jesse became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Guemar and Ghammas have been growing further apart in their street-network character since 1975.
