• Bou Saada, Algeria
• Alabama, South Africa
• Yopal, Colombia
• Lucerne, Switzerland
• Shangluo, China
• Dhamtari, India

In new street additions, Bou Saada and Lucerne both fluctuated in street-construction patterns, while Tarkeshwar built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Tarkeshwar and Bou Saada have been growing further apart in their street-network character since 1975.
