Yongzhou in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Yongzhou plotted against Hunan and China. The SNDi of new construction in Yongzhou peaked in 1976-1990, compared to Hunan which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Yongzhou's incremental SNDi fell from 2.57 to 2.56 between 1991-2005 and 2006-2020. In terms of the aggregate network, Yongzhou ranked 43rd out of 89 cities in Hunan and 873rd out of 1843 in China as of 2020.

What about similarly populated cities?
In new street additions, Yongzhou built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Mahishadal built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Acarigua built increasingly disconnected streets over time. For the full network, Yongzhou grew more disconnected from 1975 through 1976-1990, then improved, while Mahishadal became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Acarigua became progressively more disconnected. Notably, Yongzhou had a more sprawly network than Acarigua in 1975 but the two have since reversed their relative ranking.
