Qianxi in context: Street-network sprawl trends
Qianxi in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Qianxi plotted against Hebei and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Qianxi's incremental SNDi rose from 2.95 to 3.77 between 1991-2005 and 2006-2020. In terms of the aggregate network, Qianxi ranked 50th out of 120 cities in Hebei as of 2020.

What about similarly populated cities?
In new street additions, Qianxi fluctuated in its street-construction patterns, while Ponda built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Gembu built increasingly disconnected streets over time. For the full network, Qianxi and Gembu both became progressively more disconnected, while Ponda became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards.
