Luohe in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Luohe plotted against Henan and China. The SNDi of new construction in Luohe peaked in 1991-2005, compared to Henan which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Luohe's incremental SNDi fell from 3.34 to 3.24 between 1991-2005 and 2006-2020. In terms of the aggregate network, Luohe ranked 107th out of 129 cities in Henan and 1158th out of 1843 in China as of 2020.

In new street additions, Luohe built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Changshu fluctuated in its street-construction patterns and Dagupan [Lingayen] built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Luohe and Changshu have been converging in their street-network character since 1975.
