Saen Suk 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 Saen Suk plotted against Ubon Ratchathani and Thailand. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Saen Suk's incremental SNDi rose from 4.47 to 6.82 between 1991-2005 and 2006-2020. In terms of the aggregate network, Saen Suk ranked 1st out of 2 cities in Ubon Ratchathani and 6th out of 54 in Thailand as of 2020.

In new street additions, Saen Suk built increasingly disconnected streets over time, while Xingtang built increasingly disconnected streets from 1975 through 1991-2005, then improved and Ksar El Boukhari built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Saen Suk and Xingtang both became progressively more disconnected, while Ksar El Boukhari grew more disconnected from 1975 through 1976-1990, then improved. Notably, Saen Suk had a more connected network than Ksar El Boukhari in 1975 but the two have since reversed their relative ranking.
