El Khroub 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 El Khroub plotted against Constantine and Algeria. The SNDi of new construction in El Khroub was at its lowest in 1976-1990, compared to Constantine which peaked in 1991-2005 and Algeria which followed a zig-zag trend with an overall decrease. Most recently, El Khroub's incremental SNDi rose from 3.55 to 3.74 between 1991-2005 and 2006-2020. In terms of the aggregate network, El Khroub ranked 2nd out of 4 cities in Constantine and 86th out of 109 in Algeria as of 2020.

• Bilqas, Egypt

While Daik-U and Shiling both fluctuated in its street-construction patterns, El Khroub built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. For the full network, El Khroub became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Daik-U became progressively more disconnected and Shiling fluctuated in connectivity. Notably, El Khroub had a more sprawly network than Daik-U in 1975 but the two have since reversed their relative ranking.
