Lishui in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Lishui plotted against Jiangsu and China. The SNDi of new construction in Lishui was at its lowest in 1976-1990, compared to Jiangsu which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Lishui's incremental SNDi rose from 1.43 to 4.47 between 1991-2005 and 2006-2020. In terms of the aggregate network, Lishui ranked 58th out of 101 cities in Jiangsu and 976th out of 1843 in China as of 2020.

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