MarromeuVotkinskKazerun

In new street additions, Marromeu built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Votkinsk built increasingly disconnected streets over time and Kazerun fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Marromeu had a more connected network than Votkinsk in 1975 but the two have since reversed their relative ranking.
