Covè in context: Street-network sprawl trends
Cove in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Covè plotted against Zou and Benin. The SNDi of new construction in Covè rose steadily, compared to Zou which peaked in 1991-2005 and Benin which followed a zig-zag trend with an overall increase. Most recently, Covè's incremental SNDi rose from 2.18 to 3.0 between 1991-2005 and 2006-2020. In terms of the aggregate network, Covè ranked 1st out of 3 cities in Zou and 1st out of 24 in Benin as of 2020.

In new street additions, Covè and Voinjama both built increasingly disconnected streets over time, while Sanana built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Covè had a more sprawly network than Voinjama in 1975 but the two have since reversed their relative ranking.
