Durgachak 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 Durgachak plotted against West Bengal and India. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Durgachak's incremental SNDi rose from 5.47 to 8.4 between 1991-2005 and 2006-2020. In terms of the aggregate network, Durgachak ranked 96th out of 140 cities in West Bengal and 1641st out of 1868 in India as of 2020.

• Linzhou, China
• Badarpur, India
• Yuanjiang, China

In new street additions, Durgachak fluctuated in its street-construction patterns, while Xinhua built increasingly disconnected streets over time and Linzhou built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend.
