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