Curicó 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 Curicó plotted against Maule and Chile. While Maule and Chile both followed a zig-zag trend with an overall increase, Curicó's new street additions followed a zig-zag trend with an overall increase. Most recently, Curicó's incremental SNDi rose from 3.28 to 3.44 between 1991-2005 and 2006-2020. In terms of the aggregate network, Curicó ranked 3rd out of 3 cities in Maule and 25th out of 38 in Chile as of 2020.

What about similarly populated cities?

• Bonao, Dominican Republic
• Kuala Tungkal, Indonesia
• Wudu, China
• Méagui, Côte d'Ivoire
• Barawa, Somalia
• Tangyan, Myanmar

In new street additions, Curicó and Méagui both fluctuated in its street-construction patterns, while Bonao built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Curicó had a more sprawly network than Bonao in 1975 but the two have since reversed their relative ranking.
