Nanbu in context: Street-network sprawl trends
Nanbu in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Nanbu plotted against Sichuan and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Nanbu's incremental SNDi rose from 3.97 to 5.02 between 1991-2005 and 2006-2020. In terms of the aggregate network, Nanbu ranked 85th out of 98 cities in Sichuan and 1690th out of 1843 in China as of 2020.

In new street additions, Nanbu fluctuated in its street-construction patterns, while Samundri built increasingly disconnected streets from 1975 through 1991-2005, then improved and Marugame built increasingly disconnected streets over time. Looking at the full network, Samundri and Marugame both became progressively more disconnected, while Nanbu fluctuated in connectivity. Nanbu and Samundri have been converging in their street-network character since 1975.
