Ahoada 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 Ahoada plotted against Rivers and Nigeria. The SNDi of new construction in Ahoada rose steadily, compared to Rivers which rose steadily and Nigeria which followed a zig-zag trend with an overall increase. Most recently, Ahoada's incremental SNDi rose from 4.22 to 6.11 between 1991-2005 and 2006-2020. In terms of the aggregate network, Ahoada ranked 10th out of 28 cities in Rivers and 279th out of 422 in Nigeria as of 2020.

In new street additions, Ahoada built increasingly disconnected streets over time, while Mustafa Kemal built increasingly disconnected streets from 1975 through 1976-1990, then improved and Samandağ built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Ahoada became progressively more disconnected, while Mustafa Kemal fluctuated in connectivity and Samandağ became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Ahoada had a more connected network than Samandağ in 1975 but the two have since reversed their relative ranking.
