PyeongtaekDurameQihe

In new street additions, Pyeongtaek fluctuated in its street-construction patterns, while Durame built increasingly disconnected streets over time and Qihe built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Notably, Pyeongtaek had a more sprawly network than Durame in 1975 but the two have since reversed their relative ranking.
