Egbe 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 Egbe plotted against Kogi and Nigeria. The SNDi of new construction in Egbe rose steadily, compared to Kogi which rose steadily and Nigeria which followed a zig-zag trend with an overall increase. Most recently, Egbe's incremental SNDi rose from 3.95 to 4.4 between 1991-2005 and 2006-2020. In terms of the aggregate network, Egbe ranked 6th out of 11 cities in Kogi and 206th out of 422 in Nigeria as of 2020.

In new street additions, Egbe built increasingly disconnected streets over time, while Pweto built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Lakhai fluctuated in its street-construction patterns. For the full network, Egbe became progressively more disconnected, while Pweto became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Lakhai fluctuated in connectivity. Egbe and Pweto have been growing further apart in their street-network character since 1975.
