Xinjiang Uygur: region in China
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.

Trends in street network construction: The SNDis of street construction for the respective time periods are 4.77, 3.53, 4.32 and 3.53. Disconnectivity in street construction in Xinjiang Uygur follows a zig-zag trend. In 2001-2014, street construction was most disconnected, while construction was most connected in 1975.
Quantity of street network construction: The street network in Xinjiang Uygur spans a total of 21304 kilometers. The period with the greatest volume of street construction was 2001-2014. These roads have an SNDi of 3.53, which is highly disconnected.
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 4.77, 4.4, 4.54 and 4.31. Disconnectivity in Xinjiang Uygur's street network follows a zig-zag trend. In 2001-2014, the region was most disconnected; while it was most connected in 1975.
