Panruti 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 Panruti plotted against Tamil Nadu and India. The SNDi of new construction in Panruti was at its lowest in 1991-2005, compared to Tamil Nadu which rose steadily and India which followed a zig-zag trend with an overall increase. Most recently, Panruti's incremental SNDi rose from 3.5 to 3.81 between 1991-2005 and 2006-2020. In terms of the aggregate network, Panruti ranked 46th out of 121 cities in Tamil Nadu and 811th out of 1868 in India as of 2020.

In new street additions, Panruti built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Orsk built increasingly disconnected streets from 1975 through 1991-2005, then improved and Wegeda fluctuated in its street-construction patterns. Looking at the full network, Orsk and Wegeda both became progressively more disconnected, while Panruti became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Panruti and Wegeda have been converging in their street-network character since 1975.
