Xinhua: city in Hunan, 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.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Xinhua as of 2014, the overall level of street-network sprawl is 3.72, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 2.36, 2.65, 5.12 and 4.48. Street construction in Xinhua increased in disconnectivity initially but has since improved. The streets constructed in 1991-2000 were the most disconnected.
Quantity of street network construction: The street network in Xinhua spans a total of 63 kilometers. It is dominated by roads constructed in 1976-1990. These roads have an SNDi of 2.65, 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 2.36, 2.89, 3.52 and 3.72. Overall, the SNDi of the aggregate street network has risen: the street network in Xinhua has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.53 points, but between 1991-2000 and 2001-2014, it rose by just 0.21.
