Panna 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 Panna plotted against Madhya Pradesh and India. The SNDi of new construction in Panna was at its lowest in 1976-1990, compared to Madhya Pradesh which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Panna's incremental SNDi rose from 2.54 to 3.85 between 1991-2005 and 2006-2020. In terms of the aggregate network, Panna ranked 18th out of 98 cities in Madhya Pradesh and 295th out of 1868 in India as of 2020.

In new street additions, Panna built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Ban Phaeo built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Muroran fluctuated in its street-construction patterns. For the full network, Panna and Muroran both became progressively more disconnected, while Ban Phaeo became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards.
