Kani 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 Kani plotted against Gifu and Japan. While Gifu and Japan both followed a zig-zag trend with an overall increase, Kani's new street additions followed a zig-zag trend with an overall increase. Most recently, Kani's incremental SNDi rose from 2.24 to 2.79 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kani ranked 1st out of 2 cities in Gifu and 61st out of 135 in Japan as of 2020.
