Kuhdasht 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 Kuhdasht plotted against Lorestan and Iran. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Kuhdasht's incremental SNDi rose from 1.87 to 2.78 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kuhdasht ranked 3rd out of 6 cities in Lorestan and 15th out of 169 in Iran as of 2020.

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

In new street additions, Kuhdasht built increasingly disconnected streets over time, while Kattappana built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Hongtong fluctuated in its street-construction patterns. For the full network, Kuhdasht became progressively more disconnected, while Kattappana became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Hongtong grew more disconnected from 1975 through 1976-1990, then improved. Kuhdasht and Hongtong have been converging in their street-network character since 1975.
