Chirala 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 Chirala plotted against Andhra Pradesh and India. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Chirala's incremental SNDi rose from 3.78 to 3.79 between 1991-2005 and 2006-2020. In terms of the aggregate network, Chirala ranked 63rd out of 91 cities in Andhra Pradesh and 862nd out of 1868 in India as of 2020.

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

In new street additions, Chirala fluctuated in its street-construction patterns, while Chizhou built increasingly disconnected streets over time and Bangarmau built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Chirala and Chizhou both became progressively more disconnected, while Bangarmau grew more disconnected from 1975 through 1991-2005, then improved. Chirala and Chizhou have been converging in their street-network character since 1975.
