Renhuai in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Renhuai plotted against Guizhou and China. The SNDi of new construction in Renhuai peaked in 1976-1990, compared to Guizhou which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Renhuai's incremental SNDi fell from 2.44 to 2.19 between 1991-2005 and 2006-2020. In terms of the aggregate network, Renhuai ranked 12th out of 41 cities in Guizhou and 457th out of 1843 in China as of 2020.

In new street additions, Renhuai built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Ambatolahy II built increasingly disconnected streets from 1975 through 1991-2005, then improved and Zalantun fluctuated in its street-construction patterns. For the full network, Renhuai grew more disconnected from 1975 through 1976-1990, then improved, while Ambatolahy II became progressively more disconnected and Zalantun fluctuated in connectivity. Notably, Renhuai had a more sprawly network than Zalantun in 1975 but the two have since reversed their relative ranking.
