Panshi 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 Panshi plotted against Jilin and China. The SNDi of new construction in Panshi peaked in 1991-2005, compared to Jilin which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Panshi's incremental SNDi fell from 2.63 to 1.57 between 1991-2005 and 2006-2020. In terms of the aggregate network, Panshi ranked 5th out of 47 cities in Jilin and 103rd out of 1843 in China as of 2020.
