Ad-Damazin 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 Ad-Damazin plotted against Blue Nile and Sudan. The SNDi of new construction in Ad-Damazin peaked in 1991-2005, compared to Blue Nile which was at its lowest in 1991-2005 and Sudan which followed a zig-zag trend with an overall increase. Most recently, Ad-Damazin's incremental SNDi fell from 1.56 to 1.48 between 1991-2005 and 2006-2020. In terms of the aggregate network, Ad-Damazin ranked 1st out of 3 cities in Blue Nile and 23rd out of 78 in Sudan as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Ad-Damazin built increasingly disconnected streets from 1975 through 1991-2005, then improved, while 新华村 built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Zunhua fluctuated in its street-construction patterns. For the full network, Ad-Damazin and Zunhua both became progressively more disconnected, while 新华村 became progressively more connected. Ad-Damazin and 新华村 have been converging in their street-network character since 1975.
