AruAl KhorBudhana

In new street additions, Aru built increasingly disconnected streets over time, while Al Khor fluctuated in its street-construction patterns and Budhana built increasingly connected streets over time. For the full network, Aru became progressively more disconnected, while Al Khor became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Budhana grew more disconnected from 1975 through 1976-1990, then improved. Notably, Aru had a more connected network than Al Khor in 1975 but the two have since reversed their relative ranking.
