Ikole 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 Ikole plotted against Ekiti and Nigeria. While Ekiti and Nigeria both followed a zig-zag trend with an overall increase, Ikole's new street additions followed a zig-zag trend with an overall increase. Most recently, Ikole's incremental SNDi rose from 2.95 to 5.19 between 1991-2005 and 2006-2020. In terms of the aggregate network, Ikole ranked 6th out of 17 cities in Ekiti and 173rd out of 422 in Nigeria as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

• Idiofa, Democratic Republic of the Congo
• Bagan Siapi-api, Indonesia
• Arjawinangun, Indonesia
• Manbij, Syria

In new street additions, Ikole fluctuated in its street-construction patterns, while Bến Tre built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Bagan Siapi-api built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Ikole and Bagan Siapi-api have been growing further apart in their street-network character since 1975.
