Pingnan 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 Pingnan plotted against Guangxi and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Pingnan's incremental SNDi rose from 1.49 to 2.26 between 1991-2005 and 2006-2020. In terms of the aggregate network, Pingnan ranked 4th out of 63 cities in Guangxi and 231st out of 1843 in China as of 2020.

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