Namialo 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 Namialo plotted against Nampula and Mozambique. The SNDi of new construction in Namialo peaked in 1991-2005, compared to Nampula which rose steadily and Mozambique which rose steadily. Most recently, Namialo's incremental SNDi fell from 5.1 to 4.41 between 1991-2005 and 2006-2020.

In new street additions, Namialo built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Mubende built increasingly disconnected streets over time and Tari built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Namialo and Mubende both became progressively more disconnected, while Tari became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Namialo had a more sprawly network than Mubende in 1975 but the two have since reversed their relative ranking.
