What about similarly populated cities?

• Chandrapur, India
• Wuzhou, China
• Ranghulu, China
• Mannheim, Germany
• Kushtia, Bangladesh
• Bathinda, India

While Chandrapur and Mannheim both fluctuated in its street-construction patterns, Nganjuk built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Nganjuk and Mannheim have been growing further apart in their street-network character since 1975.
