What about similarly populated cities?
In new street additions, Yên Bái built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Warora fluctuated in its street-construction patterns and Kodada built increasingly disconnected streets over time. Looking at the full network, Warora and Kodada both became progressively more disconnected, while Yên Bái became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Yên Bái and Warora have been converging in their street-network character since 1975.
