For the full network, Arzuiyeh and Pyoksong both became progressively more connected, while Ambad became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Arzuiyeh had a more sprawly network than Pyoksong in 1975 but the two have since reversed their relative ranking.
