Weiqiao in context: Street-network sprawl trends
Weiqiao in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Weiqiao plotted against Shandong and China. The SNDi of new construction in Weiqiao was at its lowest in 1991-2005, compared to Shandong which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Weiqiao's incremental SNDi rose from 1.26 to 1.51 between 1991-2005 and 2006-2020. In terms of the aggregate network, Weiqiao ranked 9th out of 124 cities in Shandong and 53rd out of 1843 in China as of 2020.

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