Xining in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Xining plotted against Qinghai and China. The SNDi of new construction in Xining peaked in 1976-1990, compared to Qinghai which followed a zig-zag trend with an overall increase and China which followed a zig-zag trend with an overall increase. Most recently, Xining's incremental SNDi fell from 3.43 to 2.97 between 1991-2005 and 2006-2020. In terms of the aggregate network, Xining ranked 7th out of 10 cities in Qinghai and 1168th out of 1843 in China as of 2020.

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