Suji 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 Suji plotted against Sichuan and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Suji's incremental SNDi rose from 3.3 to 4.76 between 1991-2005 and 2006-2020. In terms of the aggregate network, Suji ranked 66th out of 98 cities in Sichuan and 1448th out of 1843 in China as of 2020.

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

In new street additions, Suji fluctuated in its street-construction patterns, while Daulatpur built increasingly disconnected streets over time and Al-Minya built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Suji fluctuated in connectivity, while Daulatpur became progressively more disconnected and Al-Minya became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Suji had a more sprawly network than Daulatpur in 1975 but the two have since reversed their relative ranking.
