Mambasa 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 Mambasa plotted against Ituri and Democratic Republic of the Congo. The SNDi of new construction in Mambasa was at its lowest in 1991-2005, compared to Ituri which was at its lowest in 1976-1990 and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Mambasa's incremental SNDi rose from 3.03 to 3.76 between 1991-2005 and 2006-2020. In terms of the aggregate network, Mambasa ranked 6th out of 8 cities in Ituri and 158th 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.
