Jinxiang 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 Jinxiang plotted against Shandong and China. The SNDi of new construction in Jinxiang was at its lowest in 1976-1990, compared to Shandong which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Jinxiang's incremental SNDi rose from 1.76 to 2.3 between 1991-2005 and 2006-2020. In terms of the aggregate network, Jinxiang ranked 34th out of 124 cities in Shandong and 196th out of 1843 in China as of 2020.

For the full network, Jinxiang became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Tha Chang became progressively more disconnected and Chakdara became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Jinxiang and Tha Chang have been growing further apart in their street-network character since 1975.
