Chandigarh in context: Street-network sprawl trends
Chandigarh in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Chandigarh plotted against Punjab and India. The SNDi of new construction in Chandigarh peaked in 1976-1990, compared to Punjab which rose steadily and India which followed a zig-zag trend with an overall increase. Most recently, Chandigarh's incremental SNDi fell from 3.69 to 3.64 between 1991-2005 and 2006-2020. In terms of the aggregate network, Chandigarh ranked 15th out of 41 cities in Punjab and 666th out of 1868 in India as of 2020.

In new street additions, Chandigarh built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Coimbatore built increasingly disconnected streets over time and Phoenix built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Chandigarh had a more connected network than Phoenix in 1975 but the two have since reversed their relative ranking.
