Sattahip 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 Sattahip plotted against Chon Buri and Thailand. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Sattahip's incremental SNDi rose from 5.43 to 6.26 between 1991-2005 and 2006-2020. In terms of the aggregate network, Sattahip ranked 3rd out of 4 cities in Chon Buri and 39th out of 54 in Thailand as of 2020.

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

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