In new street additions, Baiquan built increasingly disconnected streets over time, while Banjaran fluctuated in its street-construction patterns and Wilkes-Barre 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, Baiquan had a more connected network than Wilkes-Barre in 1975 but the two have since reversed their relative ranking.
