Norfolk in context: Street-network sprawl trends
Norfolk in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Norfolk plotted against Virginia and United States. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Norfolk's incremental SNDi fell from 5.59 to 5.45 between 1991-2005 and 2006-2020. In terms of the aggregate network, Norfolk ranked 4th out of 11 cities in Virginia and 268th out of 333 in United States as of 2020.

What about similarly populated cities?
In new street additions, Norfolk built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Londrina built increasingly disconnected streets over time and Taxila built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Norfolk and Londrina both became progressively more disconnected, while Taxila became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards.
