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