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