What about similarly populated cities?
In new street additions, Avellino built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Anchal built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Thuraiyur built increasingly disconnected streets over time. For the full network, Avellino and Thuraiyur both became progressively more disconnected, while Anchal became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Avellino and Anchal have been converging in their street-network character since 1975.
