Sanhur 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 Sanhur plotted against Al Fayyum and Egypt. The SNDi of new construction in Sanhur peaked in 1991-2005, compared to Al Fayyum which peaked in 1976-1990 and Egypt which followed a zig-zag trend with an overall increase. Most recently, Sanhur's incremental SNDi fell from 5.29 to 5.2 between 1991-2005 and 2006-2020. In terms of the aggregate network, Sanhur ranked 10th out of 13 cities in Al Fayyum and 162nd out of 213 in Egypt as of 2020.

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