Uzbekistan
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Uzbekistan as of 2014, the overall level of street-network sprawl is 3.41, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 3.25, 3.23, 4.06 and 4.18. The disconnectivity of new streets constructed in Uzbekistan fell, then rose. In 1976-1990, new street layouts were the most connected.
Quantity of street network construction: The street network in Uzbekistan spans a total of 84631 kilometers. The period with the greatest volume of street construction was 1976-1990. These roads have an SNDi of 3.23, which is in the 40th to 60th percentile of disconnectedness.
Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 3.25, 3.24, 3.31 and 3.41. The SNDi of the aggregate street network in fell at first, but Uzbekistan has worsened in disconnectivity since 1990.
The level of street-network sprawl in new development in Uzbekistan was at its lowest in 1976-1990. To get a sense of how street development has changed in Uzbekistan, we can consider three of its most populous regions: Tashkent, Ferghana and Kashkadarya. Out of the three regions, Tashkent does not follow the same trend as the country. The level of street-network sprawl in new development in Tashkent rose steadily.
How do development practices in Uzbekistan fare in comparison to others in the world? Most recently in 2001-2014, street construction in Uzbekistan was the 85th-most disconnected out of the 155 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, street construction in Uzbekistan has become more connected. Uzbekistan ranked 59th in 1975, 80th in 1976-1990, 75th in 1991-2000 and 85th in 2001-2014.
The largest city in Uzbekistan is Tashkent, with a population of 3157800 people. Taking into account the entire (i.e. aggregate) street network in Tashkent as of 2014, the overall level of street-network sprawl is 2.38, which is in the 40th to 60th percentile of disconnectedness. The level of street-network sprawl in new development in Tashkent peaked in 1991-2000.
As of 2014, the city with the most disconnected street network in Uzbekistan is Guzar with an SNDi of 4.99, which is highly disconnected. Conversely, the most connected city is Bukhara with an SNDi of 0.79, which is relatively well-connected. See trends for these cities: Bukhara, Guzar
