In new street additions, Bogota and Suzhou both fluctuated in its street-construction patterns, while Taipei built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Bogota had a more sprawly network than Taipei in 1975 but the two have since reversed their relative ranking.
