In new street additions, Luxi built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Novy Urengoy fluctuated in its street-construction patterns and Aschaffenburg built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Luxi grew more disconnected from 1975 through 1976-1990, then improved, while Novy Urengoy became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Aschaffenburg became progressively more disconnected. Notably, Luxi had a more sprawly network than Novy Urengoy in 1975 but the two have since reversed their relative ranking.
