Kotabaru in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Kotabaru plotted against Kalimantan Selatan and Indonesia. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Kotabaru's incremental SNDi rose from 4.86 to 6.27 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kotabaru ranked 6th out of 9 cities in Kalimantan Selatan and 200th out of 366 in Indonesia as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

• Guangrao, China
• Thuringowa Central, Australia

While Pyu and Wengyuan both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Kotabaru built increasingly disconnected streets over time in new street additions. For the full network, Kotabaru and Wengyuan both became progressively more disconnected, while Pyu grew more disconnected from 1975 through 1991-2005, then improved. Kotabaru and Pyu have been converging in their street-network character since 1975.
