While Pavlovo and Atamanovo both built increasingly disconnected streets over time, Arezzo built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Notably, Arezzo had a more sprawly network than Pavlovo in 1975 but the two have since reversed their relative ranking.
