Bamberg 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 Bamberg plotted against Bayern and Germany. While Bayern and Germany both rose steadily, Bamberg's new street additions rose steadily. Most recently, Bamberg's incremental SNDi rose from 2.91 to 3.1 between 1991-2005 and 2006-2020. In terms of the aggregate network, Bamberg ranked 10th out of 14 cities in Bayern and 54th out of 99 in Germany as of 2020.
