Qambar 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 Qambar plotted against Sindh and Pakistan. The SNDi of new construction in Qambar 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, Qambar's incremental SNDi rose from 3.3 to 3.47 between 1991-2005 and 2006-2020. In terms of the aggregate network, Qambar ranked 7th out of 50 cities in Sindh and 16th out of 292 in Pakistan as of 2020.

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