Tanjung 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 Tanjung plotted against Kalimantan Selatan and Indonesia. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Tanjung's incremental SNDi rose from 4.66 to 7.44 between 1991-2005 and 2006-2020. In terms of the aggregate network, Tanjung ranked 8th out of 9 cities in Kalimantan Selatan and 298th 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, Tanjung built increasingly disconnected streets over time, while Periyakulam fluctuated in its street-construction patterns and La Rochelle built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Tanjung became progressively more disconnected, while Periyakulam grew more disconnected from 1975 through 1976-1990, then improved and La Rochelle grew more disconnected from 1975 through 1991-2005, then improved. Tanjung and Periyakulam have been growing further apart in their street-network character since 1975.
