Weihe in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Weihe plotted against Heilongjiang and China. The SNDi of new construction in Weihe peaked in 1976-1990, compared to Heilongjiang which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Weihe's incremental SNDi fell from 5.3 to 2.54 between 1991-2005 and 2006-2020. In terms of the aggregate network, Weihe ranked 56th out of 67 cities in Heilongjiang and 1172nd out of 1843 in China as of 2020.

What about similarly populated cities?
In new street additions, Weihe built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Kirovo-Chepetsk built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Unna built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Weihe grew more disconnected from 1975 through 1991-2005, then improved, while Kirovo-Chepetsk became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Unna became progressively more disconnected. Weihe and Kirovo-Chepetsk have been growing further apart in their street-network character since 1975.
