Jinfeng in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Jinfeng plotted against Jiangsu and China. The SNDi of new construction in Jinfeng was at its lowest in 1991-2005, compared to Jiangsu which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Jinfeng's incremental SNDi rose from 3.76 to 4.69 between 1991-2005 and 2006-2020. In terms of the aggregate network, Jinfeng ranked 90th out of 101 cities in Jiangsu and 1555th out of 1843 in China as of 2020.

In new street additions, Jinfeng built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Nyaungdon built increasingly connected streets over time and Tshimbulu built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Jinfeng fluctuated in connectivity, while Nyaungdon became progressively more connected and Tshimbulu grew more disconnected from 1975 through 1976-1990, then improved. Notably, Jinfeng had a more connected network than Nyaungdon in 1975 but the two have since reversed their relative ranking.
