In new street additions, Doha and Kaduna both built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Munich fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Doha and Kaduna have been growing further apart in their street-network character since 1975.
