Dawei 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 Dawei plotted against Tanintharyi and Myanmar. The SNDi of new construction in Dawei was at its lowest in 1991-2005, compared to Tanintharyi which rose steadily and Myanmar which followed a zig-zag trend with an overall increase. Most recently, Dawei's incremental SNDi rose from 1.57 to 1.99 between 1991-2005 and 2006-2020. In terms of the aggregate network, Dawei ranked 1st out of 4 cities in Tanintharyi and 2nd out of 113 in Myanmar as of 2020.

In new street additions, Dawei and Wajid both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Wegeda fluctuated in its street-construction patterns. For the full network, Dawei became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Wegeda became progressively more disconnected and Wajid became progressively more connected. Dawei and Wegeda have been growing further apart in their street-network character since 1975.
