Fengxian 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 Fengxian plotted against Jiangsu and China. The SNDi of new construction in Fengxian peaked in 1991-2005, compared to Jiangsu which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Fengxian's incremental SNDi fell from 3.27 to 2.26 between 1991-2005 and 2006-2020. In terms of the aggregate network, Fengxian ranked 31st out of 101 cities in Jiangsu and 458th out of 1843 in China as of 2020.

In new street additions, Fengxian built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Río Cuarto fluctuated in its street-construction patterns and Ryongchon built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Fengxian and Río Cuarto both became progressively more disconnected, while Ryongchon became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Fengxian and Río Cuarto have been growing further apart in their street-network character since 1975.
