In new street additions, Oyo fluctuated in street-construction patterns, while Sitapur built increasingly disconnected streets over time and Abu Dhabi built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Sitapur and Abu Dhabi both became progressively more disconnected, while Oyo fluctuated in connectivity. Notably, Oyo had a more sprawly network than Sitapur in 1975, but the two have since reversed their relative ranking.
