Kobakma 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 Kobakma plotted against Papua and Indonesia. The SNDi of new construction in Kobakma was at its lowest in 1991-2005, compared to Papua which was at its lowest in 1991-2005 and Indonesia which rose steadily. Most recently, Kobakma's incremental SNDi rose from 1.01 to 3.03 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kobakma ranked 10th out of 15 cities in Papua and 311th out of 366 in Indonesia as of 2020.

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

In new street additions, Kobakma built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Tiberias built increasingly disconnected streets from 1975 through 1976-1990, then improved and Shalaambood fluctuated in its street-construction patterns. For the full network, Kobakma became progressively more connected, while Tiberias became progressively more disconnected and Shalaambood fluctuated in connectivity. Notably, Kobakma had a more sprawly network than Tiberias in 1975 but the two have since reversed their relative ranking.
