Tha Chang 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 Tha Chang plotted against Chanthaburi and Thailand. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Tha Chang's incremental SNDi rose from 5.05 to 6.87 between 1991-2005 and 2006-2020. In terms of the aggregate network, Tha Chang ranked 1st out of 1 cities in Chanthaburi and 30th out of 54 in Thailand as of 2020.

In new street additions, Tha Chang built increasingly disconnected streets over time, while Suifenhe fluctuated in its street-construction patterns and Jinxiang built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Tha Chang and Suifenhe both became progressively more disconnected, while Jinxiang became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Tha Chang and Suifenhe have been growing further apart in their street-network character since 1975.
