Vladivostok 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 Vladivostok plotted against Primor'ye and Russia. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Vladivostok's incremental SNDi rose from 2.51 to 2.57 between 1991-2005 and 2006-2020. In terms of the aggregate network, Vladivostok ranked 1st out of 5 cities in Primor'ye and 23rd out of 252 in Russia as of 2020.

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