SiniloanChharodiEkero

In new street additions, Siniloan fluctuated in its street-construction patterns, while Chharodi built increasingly disconnected streets over time and Ekerö built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Siniloan and Ekerö have been converging in their street-network character since 1975.
