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