Kisaran 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 Kisaran plotted against Sumatera Utara and Indonesia. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Kisaran's incremental SNDi rose from 5.74 to 5.99 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kisaran ranked 10th out of 21 cities in Sumatera Utara and 235th out of 366 in Indonesia as of 2020.

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