KoboShindandLeku

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