Crimea: region in Ukraine
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 Crimea as of 2014, the overall level of street-network sprawl is 2.78, which is in the 40th to 60th percentile of disconnectedness.
Trends in street network construction: The SNDis of street construction for the respective time periods are 2.77, 2.53, 3.57 and 4.21. The disconnectivity of new streets constructed in Crimea fell, then rose. In 1976-1990, new street layouts were the most connected.
Quantity of street network construction: The street network in Crimea spans a total of 16091 kilometers. It is dominated by roads constructed in 1976-1990. These roads have an SNDi of 2.53, 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 2.77, 2.65, 2.73 and 2.78. The SNDi of the aggregate street network in fell at first, but Crimea has worsened in disconnectivity since 1990.
The level of street-network sprawl in new development in Crimea was at its lowest in 1976-1990. To get a sense of how street development has changed in Crimea, we can consider three of its most populous cities: Simferopol, Yevpatoriya and Kerch. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Simferopol was at its lowest in 1991-2000. The level of street-network sprawl in new development in Yevpatoriya followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Kerch was at its lowest in 1991-2000.
How do development practices in Crimea fare in comparison to others in Ukraine? Most recently in 2001-2014, street construction in Crimea was the 22nd-most disconnected out of the 27 regions in Ukraine. Its position in the ranks since 1975 has fallen; relative to other regions in Ukraine, street construction in Crimea has become more connected. Crimea ranked 17th in 1975, 24th in 1976-1990, 24th in 1991-2000 and 22nd in 2001-2014.
As of 2014, the city with the most disconnected street network in Crimea is Yalta with an SNDi of 3.4, which is highly disconnected. Conversely, the most connected city is Yevpatoriya with an SNDi of 0.88, which is relatively well-connected. See trends for these cities: Yevpatoriya, Yalta
