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