While Bingöl and Tandil both fluctuated in its street-construction patterns, Al Khalis 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, Al Khalis had a more connected network than Bingöl in 1975 but the two have since reversed their relative ranking.
