Shunqing in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Shunqing plotted against Sichuan and China. The SNDi of new construction in Shunqing was at its lowest in 1976-1990, compared to Sichuan which followed a zig-zag trend with an overall increase and China which followed a zig-zag trend with an overall increase. Most recently, Shunqing's incremental SNDi rose from 2.24 to 3.35 between 1991-2005 and 2006-2020. In terms of the aggregate network, Shunqing ranked 29th out of 98 cities in Sichuan and 713th out of 1843 in China as of 2020.

In new street additions, Shunqing built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Fushun built increasingly disconnected streets from 1975 through 1991-2005, then improved and Jerusalem built increasingly disconnected streets over time. Looking at the full network, Fushun and Jerusalem both became progressively more disconnected, while Shunqing became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Shunqing and Jerusalem have been growing further apart in their street-network character since 1975.
