Samaguri 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 Samaguri plotted against Assam and India. The SNDi of new construction in Samaguri peaked in 1976-1990, compared to Assam which rose steadily and India which followed a zig-zag trend with an overall increase. Most recently, Samaguri's incremental SNDi fell from 2.61 to 1.15 between 1991-2005 and 2006-2020. In terms of the aggregate network, Samaguri ranked 13th out of 67 cities in Assam and 325th out of 1868 in India as of 2020.

In new street additions, Samaguri built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Aykel built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Choluteca built increasingly disconnected streets over time. For the full network, Samaguri grew more disconnected from 1975 through 1976-1990, then improved, while Aykel became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Choluteca became progressively more disconnected. Notably, Samaguri had a more connected network than Aykel in 1975 but the two have since reversed their relative ranking.
