Chizhou: city in Anhui, 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 Chizhou as of 2014, the overall level of street-network sprawl is 0.93, which is relatively well-connected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 0.8, 0.31, 1.0 and 2.01. The disconnectivity of new streets constructed in Chizhou fell, then rose. In 1976-1990, new street layouts were the most connected.
Quantity of street network construction: The street network in Chizhou spans a total of 149 kilometers. The period with the greatest volume of street construction was 1991-2000. These roads have an SNDi of 1.0, which is relatively well-connected.
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 0.8, 0.7, 0.82 and 0.93. The SNDi of the aggregate street network in fell at first, but Chizhou has worsened in disconnectivity since 1990.
