Panaji 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 Panaji plotted against Goa and India. The SNDi of new construction in Panaji was at its lowest in 1976-1990, compared to Goa which was at its lowest in 1976-1990 and India which followed a zig-zag trend with an overall increase. Most recently, Panaji's incremental SNDi rose from 3.75 to 4.81 between 1991-2005 and 2006-2020. In terms of the aggregate network, Panaji ranked 1st out of 5 cities in Goa and 978th out of 1868 in India as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

What about similarly populated cities?

• Banyuwangi, Indonesia
• Dengfeng, China
• Yongnian, China
• Metallurgicheskiy District, Russia
• Riohacha, Colombia
• Guanghan, China

While Banyuwangi and Metallurgicheskiy District both built increasingly disconnected streets over time, Panaji built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. For the full street network, though, all three cities follow the same trend. Notably, Panaji had a more sprawly network than Banyuwangi in 1975 but the two have since reversed their relative ranking.
