Baku in context: Street-network sprawl trends
Baku in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Baku plotted against Absheron and Azerbaijan. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Baku's incremental SNDi fell from 5.77 to 5.21 between 1991-2005 and 2006-2020. In terms of the aggregate network, Baku ranked 1st out of 2 cities in Absheron and 15th out of 20 in Azerbaijan as of 2020.

What about similarly populated cities?
In new street additions, Baku built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Phnom Penh built increasingly disconnected streets over time and Ponnani built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Baku and Phnom Penh both became progressively more disconnected, while Ponnani became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Baku and Phnom Penh have been converging in their street-network character since 1975.
