Suez 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 Suez plotted against As Suways and Egypt. The SNDi of new construction in Suez peaked in 1976-1990, compared to As Suways which peaked in 1976-1990 and Egypt which followed a zig-zag trend with an overall increase. Most recently, Suez's incremental SNDi fell from 2.55 to 2.26 between 1991-2005 and 2006-2020. In terms of the aggregate network, Suez ranked 1st out of 1 cities in As Suways and 19th out of 213 in Egypt as of 2020.

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

What about similarly populated cities?

• Pietermaritzburg, South Africa
• Huzhou, China
• Longyan, China
• Santiago de Cuba, Cuba
• Sambhal, India
• Irkutsk, Russia

In new street additions, Suez built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Pietermaritzburg built increasingly disconnected streets over time and Santiago de Cuba built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Suez and Pietermaritzburg have been growing further apart in their street-network character since 1975.
