The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Panvel plotted against Maharashtra and India. The SNDi of new construction in Panvel peaked in 1976-1990, compared to Maharashtra which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Panvel's incremental SNDi fell from 3.65 to 3.61 between 1991-2005 and 2006-2020. In terms of the aggregate network, Panvel ranked 111th out of 157 cities in Maharashtra and 837th out of 1868 in India as of 2020.

In new street additions, Panvel built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Florianópolis built increasingly disconnected streets over time and Morelia fluctuated in its street-construction patterns. Looking at the full network, Florianópolis and Morelia both became progressively more disconnected, while Panvel grew more disconnected from 1975 through 1991-2005, then improved. Notably, Panvel had a more sprawly network than Florianópolis in 1975 but the two have since reversed their relative ranking.
