ChachoengsaoHaluaghatMedenine

In new street additions, Chachoengsao built increasingly disconnected streets over time, while Haluaghat built increasingly disconnected streets from 1975 through 1991-2005, then improved and Medenine fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Chachoengsao and Haluaghat have been growing further apart in their street-network character since 1975.
