Rubaya 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 Rubaya plotted against Nord-Kivu and Democratic Republic of the Congo. The SNDi of new construction in Rubaya was at its lowest in 1991-2005, compared to Nord-Kivu which followed a zig-zag trend with an overall increase and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Rubaya's incremental SNDi rose from 4.9 to 5.21 between 1991-2005 and 2006-2020. In terms of the aggregate network, Rubaya ranked 12th out of 16 cities in Nord-Kivu and 165th out of 186 in Democratic Republic of the Congo as of 2020.

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

In new street additions, Rubaya and Chakia both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Tongnan fluctuated in its street-construction patterns. For the full network, Rubaya became progressively more connected, while Tongnan grew more disconnected from 1975 through 1976-1990, then improved and Chakia became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Rubaya and Tongnan have been converging in their street-network character since 1975.
