Kamiji 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 Kamiji plotted against Lomami and Democratic Republic of the Congo. The SNDi of new construction in Kamiji was at its lowest in 1976-1990, compared to Lomami which rose steadily and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Kamiji's incremental SNDi rose from 1.08 to 1.35 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kamiji ranked 2nd out of 8 cities in Lomami and 3rd out of 186 in Democratic Republic of the Congo as of 2020.
