What about similarly populated cities?
- Bandar Lampung, Indonesia
- Bhubaneshwar, India
- Xiangyang, China
- Huizhou, China
- Cologne, Germany
- Maiduguri, Nigeria
While Bandar Lampung and Huizhou both built increasingly disconnected streets over time, Tbilisi 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. Tbilisi and Bandar Lampung have been growing further apart in their street-network character since 1975.
