Udalguri 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 Udalguri plotted against Assam and India. The SNDi of new construction in Udalguri rose steadily, compared to Assam which rose steadily and India which followed a zig-zag trend with an overall increase. Most recently, Udalguri's incremental SNDi rose from 3.15 to 7.81 between 1991-2005 and 2006-2020. In terms of the aggregate network, Udalguri ranked 9th out of 67 cities in Assam and 216th out of 1868 in India as of 2020.

In new street additions, Udalguri built increasingly disconnected streets over time, while Chester built increasingly disconnected streets from 1975 through 1991-2005, then improved and Pouytenga built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Udalguri and Chester both became progressively more disconnected, while Pouytenga became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Udalguri and Pouytenga have been converging in their street-network character since 1975.
