Baduria 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 Baduria plotted against West Bengal and India. The SNDi of new construction in Baduria was at its lowest in 1976-1990, compared to West Bengal which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Baduria's incremental SNDi rose from 5.61 to 6.02 between 1991-2005 and 2006-2020. In terms of the aggregate network, Baduria ranked 99th out of 140 cities in West Bengal and 1652nd out of 1868 in India as of 2020.

In new street additions, Dili and Xuanwei both fluctuated in street-construction patterns, while Baduria built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Baduria became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Dili became progressively more disconnected and Xuanwei grew more disconnected from 1975 through 1976-1990, then improved. Baduria and Dili have been converging in their street-network character since 1975.
