Boende 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 Boende plotted against Tshuapa and Democratic Republic of the Congo. The SNDi of new construction in Boende peaked in 1991-2005, compared to Tshuapa which followed a zig-zag trend with an overall increase and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Boende's incremental SNDi fell from 3.65 to 3.52 between 1991-2005 and 2006-2020. In terms of the aggregate network, Boende ranked 1st out of 1 cities in Tshuapa and 87th out of 186 in Democratic Republic of the Congo as of 2020.

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

• Amarillo, United States

In new street additions, Boende built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Mejia built increasingly disconnected streets over time and Yangsan fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Boende and Mejia have been converging in their street-network character since 1975.
