Hiriyur 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 Hiriyur plotted against Karnataka and India. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Hiriyur's incremental SNDi rose from 3.25 to 4.1 between 1991-2005 and 2006-2020. In terms of the aggregate network, Hiriyur ranked 30th out of 96 cities in Karnataka and 367th 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, Hiriyur fluctuated in its street-construction patterns, while Sentani built increasingly disconnected streets from 1975 through 1991-2005, then improved and Risod built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Hiriyur and Sentani both became progressively more disconnected, while Risod fluctuated in connectivity. Hiriyur and Risod have been growing further apart in their street-network character since 1975.
