新垵 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 新垵 plotted against Fujian and China. The SNDi of new construction in 新垵 was at its lowest in 1976-1990, compared to Fujian which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, 新垵's incremental SNDi rose from 2.84 to 3.19 between 1991-2005 and 2006-2020. In terms of the aggregate network, 新垵 ranked 33rd out of 75 cities in Fujian and 1054th 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?

• Battambang, Cambodia
• Bukan, Iran
• Chikkamagaluru, India
• Obihiro, Japan
• Sultan Bathery, India
• Lubuklinggau, Indonesia

While Battambang and Obihiro both built increasingly disconnected streets over time, 新垵 built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. Looking at the full network, Battambang and Obihiro both became progressively more disconnected, while 新垵 became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, 新垵 had a more sprawly network than Battambang in 1975 but the two have since reversed their relative ranking.
