Afuze 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 Afuze plotted against Edo and Nigeria. The SNDi of new construction in Afuze rose steadily, compared to Edo which rose steadily and Nigeria which followed a zig-zag trend with an overall increase. Most recently, Afuze's incremental SNDi rose from 2.68 to 4.2 between 1991-2005 and 2006-2020. In terms of the aggregate network, Afuze ranked 3rd out of 12 cities in Edo and 138th out of 422 in Nigeria as of 2020.

In new street additions, Afuze built increasingly disconnected streets over time, while As Saddah fluctuated in its street-construction patterns and Nagahama built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Afuze became progressively more disconnected, while As Saddah grew more disconnected from 1975 through 1976-1990, then improved and Nagahama became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Afuze and As Saddah have been growing further apart in their street-network character since 1975.
