Renk 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 Renk plotted against Upper Nile and South Sudan. The SNDi of new construction in Renk was at its lowest in 1991-2005, compared to Upper Nile which was at its lowest in 1991-2005 and South Sudan which followed a zig-zag trend with an overall increase. Most recently, Renk's incremental SNDi rose from 0.89 to 1.13 between 1991-2005 and 2006-2020. In terms of the aggregate network, Renk ranked 1st out of 2 cities in Upper Nile and 1st out of 16 in South Sudan as of 2020.

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

In new street additions, Renk built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Dhaka fluctuated in its street-construction patterns and Zhoukoudian built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Renk became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Dhaka grew more disconnected from 1975 through 1976-1990, then improved and Zhoukoudian became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Renk and Dhaka have been growing further apart in their street-network character since 1975.
