Danbei in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Danbei plotted against Jiangsu and China. The SNDi of new construction in Danbei 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, Danbei's incremental SNDi rose from 3.26 to 3.71 between 1991-2005 and 2006-2020. In terms of the aggregate network, Danbei ranked 77th out of 101 cities in Jiangsu and 1320th out of 1843 in China as of 2020.

What about similarly populated cities?
In new street additions, Danbei built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Shimen fluctuated in its street-construction patterns and Shizhu built increasingly disconnected streets over time. For the full network, Danbei became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Shimen fluctuated in connectivity and Shizhu became progressively more disconnected. Danbei and Shimen have been growing further apart in their street-network character since 1975.
