The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in India, for both new street additions (left) and the aggregate street network (right).
India in context: Street-network sprawl of new development
The level of street-network sprawl in new development in India followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in India, we can consider three of its most populous regions: Uttar Pradesh, Maharashtra and Bihar. Disconnectivity in the most populous cities in India follow the same country trend.
How do development practices in India fare in comparison to others in the world? Most recently in 2006-2020, street construction in India was the 119th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in India has become more disconnected. India ranked 126th in 1975, 115th in 1976-1990, 103rd in 1991-2005 and 119th in 2006-2020.
The largest city in India is New Delhi, with a population of 26513100 people. Taking into account the entire (i.e. aggregate) street network in New Delhi as of 2020, the overall level of street-network sprawl is 3.23, which is moderately connected. The level of street-network sprawl in new development in New Delhi rose steadily.
India in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in India is Chandanpur with an SNDi of 29.2, which is very sprawly. Conversely, the most connected city is Porsa with an SNDi of 0.46, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Porsa, Chandanpur.
The level of street-network sprawl in the aggregate network in India rose steadily. To get a sense of how the aggregate street network has changed in India, we can consider three of its most populous regions: Uttar Pradesh, Maharashtra and Bihar. Disconnectivity in the most populous cities in India follow the same country trend.
