Famenin 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 Famenin plotted against Hamadan and Iran. The SNDi of new construction in Famenin was at its lowest in 1991-2005, compared to Hamadan which was at its lowest in 1976-1990 and Iran which rose steadily. Most recently, Famenin's incremental SNDi rose from 2.27 to 2.62 between 1991-2005 and 2006-2020. In terms of the aggregate network, Famenin ranked 2nd out of 5 cities in Hamadan and 41st out of 169 in Iran as of 2020.

In new street additions, Famenin built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Cangnan built increasingly disconnected streets over time and Zhaotong built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Famenin became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Cangnan became progressively more disconnected and Zhaotong grew more disconnected from 1975 through 1991-2005, then improved. Notably, Famenin had a more sprawly network than Cangnan in 1975 but the two have since reversed their relative ranking.
