Digri 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 Digri plotted against Sindh and Pakistan. The SNDi of new construction in Digri was at its lowest in 1976-1990, compared to Sindh which followed a zig-zag trend with an overall increase and Pakistan which followed a zig-zag trend with an overall increase. Most recently, Digri's incremental SNDi rose from 1.4 to 6.88 between 1991-2005 and 2006-2020. In terms of the aggregate network, Digri ranked 1st out of 50 cities in Sindh and 2nd out of 292 in Pakistan as of 2020.

In new street additions, Digri built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Sant Andreu de la Barca fluctuated in its street-construction patterns and Shahbazpur built increasingly disconnected streets over time. Looking at the full network, Sant Andreu de la Barca and Shahbazpur both became progressively more disconnected, while Digri became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Digri and Sant Andreu de la Barca have been growing further apart in their street-network character since 1975.
