In new street additions, Gerlingen built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Masrif Shinu built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Aguié built increasingly disconnected streets over time. For the full network, Gerlingen and Aguié both became progressively more disconnected, while Masrif Shinu became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Gerlingen had a more sprawly network than Aguié in 1975 but the two have since reversed their relative ranking.
