Hutou 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 Hutou plotted against Fujian and China. The SNDi of new construction in Hutou peaked in 1991-2005, compared to Fujian which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Hutou's incremental SNDi fell from 3.92 to 3.62 between 1991-2005 and 2006-2020. In terms of the aggregate network, Hutou ranked 38th out of 75 cities in Fujian and 1210th out of 1843 in China as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

What about similarly populated cities?

• Kheragarh, India
• Itacoatiara, Brazil
• Amber, India
• Điện Biên Phủ, Vietnam
• Cuamba, Mozambique
• Xiuwen, China

While Kheragarh and Điện Biên Phủ both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, Hutou built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full network, Hutou grew more disconnected from 1975 through 1991-2005, then improved, while Kheragarh became progressively more connected and Điện Biên Phủ became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Hutou and Kheragarh have been converging in their street-network character since 1975.
