Zliten 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 Zliten plotted against Al Marqab and Libya. The SNDi of new construction in Zliten peaked in 1991-2005, compared to Al Marqab which peaked in 1991-2005 and Libya which peaked in 1976-1990. Most recently, Zliten's incremental SNDi fell from 5.26 to 5.24 between 1991-2005 and 2006-2020. In terms of the aggregate network, Zliten ranked 1st out of 2 cities in Al Marqab and 10th out of 13 in Libya as of 2020.

In new street additions, Zliten and Myan Aung both built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Bamian built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Zliten and Myan Aung both became progressively more disconnected, while Bamian became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Zliten and Bamian have been converging in their street-network character since 1975.
