Moshi 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 Moshi plotted against Kilimanjaro and Tanzania. The SNDi of new construction in Moshi peaked in 1976-1990, compared to Kilimanjaro which followed a zig-zag trend with an overall decrease and Tanzania which was at its lowest in 1976-1990. Most recently, Moshi's incremental SNDi fell from 3.6 to 3.3 between 1991-2005 and 2006-2020. In terms of the aggregate network, Moshi ranked 1st out of 1 cities in Kilimanjaro and 36th out of 45 in Tanzania as of 2020.

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

• Volzhskiy, Russia
• Akita, Japan
• Mossoró, Brazil

In new street additions, Moshi built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Pangkalpinang built increasingly disconnected streets over time and Volzhskiy built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Moshi and Pangkalpinang both became progressively more disconnected, while Volzhskiy became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Moshi and Pangkalpinang have been growing further apart in their street-network character since 1975.
